Air purifiers are a common household equipment nowadays. With the onset of winters in Northern States, the demand for air purifiers has increased. The fast-approaching festive season is also a reason why homeowners concerned by rising air pollution are rushing to buy air purifiers.
The air purifier is a unique product in the list of white goods available in the market. It does not promise to provide cooler air or bring down the ambient temperature, albeit it promises fresher air. While our ancestors might have scoffed at the idea, living in a metro city today is akin to smoking a pack of cigarettes daily. The average life expectancy of people living in Delhi NCR and other major urban centres is 2 to 3 years less than people living in relatively cleaner urban and rural hinterlands. So, the promise of clean air definitely has an appeal for people who are environmentally aware and know about health issues that are caused by indoor air pollution.
Now, there are several technologies in use today for indoor air filtration. However, the most effective and widely used technology is High-efficiency Particulate Arrestance air filtration. We know that’s a mouthful so we will be using the popular acronym, HEPA, from now on. So, let’s understand how HEPA air filters work.
High-Efficiency Particulate Arrestance (HEPA)
The simplest form of filtration is to use a material with holes that are big enough to trap some particles and small enough to let through others. That is how a normal sieve works. An air filter is also like a sieve that traps particles in the ambient air. But how do you catch particles that are floating in the air? Well, by making a very fine filter with holes small enough to let air through but trap everything else. That’s what we call a HEPA filter. It can trap almost 99.97% of the dust particles and polluting agents in the air. But there is a catch.
The holes in a HEPA filter are so small that they will simply get clogged by larger dust particles that get pulled in by the air purifier’s fan. Therefore, for a HEPA filter to run efficiently, a pre-filter is needed. The pre-filter is a simple sieve that stops the larger dirt particles and hair from reaching the HEPA filter but allow the microscopic matter to escape.
Thence comes the HEPA filter. It has a paper-like look. The material is folded in a zig-zag fashion and looks like a concertina. However, the mat is actually a form of dense fibre glass which cleans the incoming air using three very different mechanisms.
- Particles that travelling at high speeds because they are lighter, get trapped as they smash into the fibre wall.
- Particles at travelling at moderate speeds are snagged by the fibres in the material as they rush by the fibre wall.
- Lastly, slow moving, relatively heavier dust particles wander around the filter for a time before sticking to the filter walls.
Together, these mechanisms enable the high efficiency of indoor air filtration we experience with HEPA air filters.
Fun Fact: HEPA filters were originally developed for the Manhattan Project, to capture the dangerous, radioactive dust produced by nuclear fission. Today, these filters are widely used for making indoor air filtration systems for factories and workplaces where dust is produced as an operational by-product.
Types of HEPA Filters
With adoption for commercial and home use, the HEPA technology has witnesses some further bifurcation in terms of quality and use-cases.
True HEPA: A high-quality HEPA filter that can trap 99.97% of dust particles that are 0.3 microns in diameter. For comparisons sake, a human hair is about 50 to 150 microns in diameter. So, a true HEPA filter is effectively trapping particles several hundred time smaller than the width of a human hair.
HEPA Filters in Breathing Masks: The second grade of HEPA filters is used in pollution masks and respiratory equipment. These are often graded in 9 different types and have three levels of efficiency (95, 99 and 99.97) combined with three levels of filter degradation resistance (N, R, and P). The higher the quality, the longer the mask with HEPA filtration can be worn.
Things to Look for When Buying an Air Purifier
Well, it goes without saying that an air purifier with a true HEPA filter is the one you want for your home. It is the most effective at filtering particulate matter which is the term used for extremely small air pollutants. A genuine HEPA filter can remove particles rated between 2.5 to 10 microns in diameter. These particles include the sooty pollutants from vehicular emissions, household dust, pet dander, fur and hair. Moreover, a true HEPA filter is also more hygienic and resistant to degradation and can filter certain types of microbes, including viral and bacterial elements and mould spores.
The second thing to look for in a home air purifier is the addition of activated carbon filters. These filters provide an extra layer of protection by removing volatile organic compounds like formaldehyde and gaseous elements like carbon monoxide from the air filtered by the HEPA filter. Activated carbon also neutralises odours, providing relief from pollutants like second-hand smoke, off-gassing from plastics, and harmful fumes produced by paints and varnishes.
Honeywell Air Purifiers for Home and Office
Now that you know what to look for in a home air filtration system, here is where you can look for it. Honeywell is one of the leading names in smart home products. Honeywell air purifiers are rated for their high-efficiency and inclusion of patented HiSivTM activated carbon filters. Moreover, our tool-free mechanism and child-safe air purifier designs ensure convenience and safety during day-to-day household use.
Now you can check the complete range of Honeywell air purifiers online at www.honeywellconnection.com or at your favourite online shopping portals like Amazon and Flipkart. Or, you can visit the nearest Chroma Store or Honeywell Air Purifier dealer for a live product demo.
Every home product requires regular maintenance to operate at full capacity. More so when you are using a product as critical as an Air Purifier, because these units are responsible for the health and well-being of your family and loved ones.
The filters in an air purifier are rated for up to 3,000 hours of operation. But that number may come down significantly when you are living in heavily polluted urban environments. For example, when using an air purifier in Delhi, you may have to replace air filters more frequently. Cities like Delhi and Gurgaon face constantly high air pollution during the winter months, which means you air purifier is working overtime to provide clean air; hence the air filters are deteriorating at a faster pace as well.
If you own an air purifier, you’ll have to think about air purifier filter replacement at one point or another. In today’s post, we will walk you through steps which can help you identify faulty filters and take action. We are also listing some steps for prolonging air filter life of your air purifier.
Do note that different air purifiers come with different mechanisms for air filter change and maintenance. Similarly, the life of the HEPA and activated carbon filters is subject to their quality.
Air Purifier HEPA Filter Replacement
The high resistance particulate air filter (HEPA) is the most advanced air filtration product in the world at the moment. It is used to filter dust particles as small as 0.03 microns. The HEPA filter offers protection from hazardous PM2.5 particles, making it a critical working part of your air purifier.
You can easily check the HEPA air filter health by opening the unit and visually inspecting it. If the filter has changed color from white to a yellowish hue or a dark grey color, then replacement is immediately needed. You should also check for any tears in the HEPA filter due to poor handling to make sure it is working at 100 percent.

Replacing the Activated Carbon Filter
The second most important part of your air filter setup is the activated carbon filter. It removes gaseous elements, odors and volatile organic compounds like formaldehyde, carbon monoxide, and nitrogen dioxide from the air. Usually, the activated carbon filter should be replaced after 3,000 hours of use. Mathematically it is about 125 days, depending on ambient air quality. But again, nowadays people are using air purifiers 24 hours a day to escape bad air quality in metro cities, so the actual service life can vary. Air purifiers with filter replacement indicators can help you identify an old filter and replace it promptly.
The pre-filter used in air purifiers is meant for extending the efficiency and life of the two main filters. Check the filter every 15 days for dust and debris to ensure smooth airflow inside the unit. In case the pre-filter gets damaged, you should get a replacement promptly to protect the HEPA and activated carbon filter.
So, that concludes the part on checking the air filters for age and damage. Now to the promised tips for extending the life of air purifier filters.
- Keep the area around the air purifier clean so that the unit does not need to do unnecessary air clean-ups.
- Clean the air inlets and insides of the unit with a dry microfiber cloth to keep debris from accumula1ting inside the air purifier.
- Place the purifier in an open area for free inflow and outflow of air.
- Make sure that the air purifier is used in a closed space, otherwise, the filters may get worn much sooner.
- Use mops for cleaning floors, instead of brooms. Wet and dry mops can drastically reduce the dust and hair particles floating in ambient air.
- Also, replace good quality dusting cloths to make sure the maximum amount is trapped and removed effectively.
Air pollution is increasing with every day in India’s urban centers like Delhi NCR, Bangalore and Mumbai. We see people wearing pollution masks and travelling in closed vehicles to be safe from the harmful effects of particulate matter or PM2.5/PM10 as they are popularly known. Some of us have gone even a step further and bought a car air purifiers to ensure maximum safety from air pollutants while travelling. But which one is the best solution of them all?
Here, we do a comparison of the protection offered by air pollution masks and car air purifiers, so that you can decide for yourself about the effectiveness of these popular products.
Car Air Purifiers
High-quality car air purifiers like our Move Pure and Move Pure 2 come with hybrid HEPA filters. These filters combine the particulate arrestance technology with activated carbon filtration to remove over 99 percent of air pollutants, like PM2.5, PM10, volatile organic compounds, cigarette smoke, and foul odors.
These portable air purifier units can be mounted on the dashboard or placed under the seats or in the rear parcel tray. The noise levels from a car air purifier are comparable to your car’s air blower and do not create any distractions while you are driving.
Comparing the Two Technologies
Where a car air purifier has higher filtration efficiency, a pollution mask is more portable and protects you even when you move out of the vehicle’s cabin. However, a car air purifier not only protects you from air pollution but also safeguards your fellow passengers. In addition, a car air purifier removes unwanted smells and dust from your car’s insides, keeping it smelling fresh.
In our opinion, it wouldn’t hurt to buy both the car air purifier and a pollution mask for all-around protection from air pollution. In the meanwhile, you can visit us at www.honeywellconnection.com to know more about the air purifiers and pollution masks.
Living in a mega city gives you access to many facilities and services which are not available in smaller towns. But on the flip side, such mega cities, and especially Indian mega cities are witnessing a rampant infrastructure growth which in some ways is affecting our environment. One of the biggest problems arising out of this situation is Air Pollution.
A recent survey concluded that India is home to 13 of the 20 most polluted cities in the world (Ref.). Many foreign embassies and government institutions have installed air filtration units for protection against the rising levels of hazardous pollutants. While this is pertinent to outdoor air quality, the air that we breathe indoors is no better. On one hand the ambient air quality adversely affects the indoor air quality, on the other hand there are multiple sources of pollution residing inside our home itself.
We live indoors, why should we buy a home air purifier?
According to a study, indoor air pollution is one of the leading causes of pollution related deaths in India. Also, in metro cities like Bangalore, almost 50% youth and children below 18 years are suffering from asthma (Ref.).
Contrary to the popular belief that we are safe from pollution inside our homes, there are several air pollutants that thrive indoors and can cause health issues for you and your newly born baby.
- Carbon Mono-oxide particles entering from outside
- Microbial growths like fungi and mould that develop in damp places
- Allergens such as dust, pollen, pet dander, and kitchen smoke, etc.
- Airborne germs and viruses that are carried by pets or people, causing fever, flu and other health issues
- Toxic compounds that can mix in the air such as pesticides, herbicides, etc.
This is worrying news for the common people, and more so for those soon to be parents or with new borns. Children and new born babies breathe almost 50 percent more air than adults do (Ref.).Since a baby’s lungs are still developing and are delicate, presence of airborne toxins and allergens can have a negative impact on his health.Sometimes unclean air in the home can have long term health effects on new born babies, hampering natural growth, causing respiratory problems like asthma and weaker immunity against flus.
Fortunately, home air purifiers have become much more easily available and affordable than they were a few years ago. The indoor air purifiers have a compact size and have low service & maintenance requirements. If you are living in an Indian city and have a new born baby in the house, it is imperative that you buy an air purifier for home. However do ensure that the products that your look up for come with a design that does not have sharp edges and the filters are not exposed from any side, for the safety of your children. Another important factor to keep in mind is that the device should not produce any ozone as a byproduct of air filtration.
What to look for when buying an air purifier for a baby?
- The air purifier must not emit Ozone, which is damaging for both infants and adults.
- The air purifier should effectively remove toxic chemical gases from your home environment. There are several gases which are generally present inside homes, such as Formaldehyde, Volatile Organic Compounds, Carbon Monoxide, Sulphur Dioxide, etc.
- The air purifier should also be effective againstultra-fine air pollutants such as pet dander, airborne bacteria and viruses, dust mites, cooking smoke and soot.
The reason why air pollution is such a dangerous thing for our health and well-being is its odourless and colourless nature. Fine dust particles and volatile organic compounds are not visible to the naked eye, thus making us oblivious to the effects of air pollution.
Did you know? Polluted air is not something that exists in remote industrial complexes. In fact, indoor air pollution in our homes can be 10 times higher than outdoor air pollution these days.
As almost 90 percent of our time is spend indoors, this polluted can have drastic effects on our health. In today’s post we are sharing a list of common air pollutants, and also how an air purifier can clean indoor air.
Common air pollutants found in homes
Here is why you need an air cleaner.
- Dust particles that can be as small as 0.3 microns, capable of entering the bloodstream through the respiratory system.
- Household chemiclas like insecticides, herbisides and pesticides which can release toxic fumes if not stored properly. These substances are often carcinogenic as well.
- Byproducts of chlorine like chloramines and trihelomethanes which are formed by reaction of chlorine with biological matter. If inhaled regularly these elements can cause damage to the lungs.
- Volatile organic compounds that are released by household cleaning agents, paints and other solvents. VOCs like formaldehyde are commonly used in adhesives and can manifest as fumes which are carcinogenic.
- Syenthetic fragrances from air fresheners, deodorants and perfumes can also contain highly or semi volatile chemical agents.
- Household linens can also contain a large amount of fine dust particles along with dry-cleaned clothes which may have traces of trichloroethlylene and perchloroethylene (both known carcinogens).
- Pet hair and dander are another major cause of indoor air pollution for homeowners with little furry friends. Pet hair, and fur are lightweight and can float about in the ambient air. Thus, frequently entering your repiratory system. Moreover, pet hair and dander can also trigger underlying conditions like asthma and repiratory allergies.
- Radon gas from kitchen activities is one of the leading causes of cancer in the world. It is released from certain types of kitchen counter tops and is also found in attics and basements.
- Second hand cigarette smoke is not only responsible for causing that pungent smell that hangs about for days but can also contains 43 known carcinogens.
But don’t worry, there is a veritable way of getting rid of these air pollutants and improving the indoor air quality of your home – Air Purifiers.
How our air purifiers work?
Our air purifiers use patented filtration technologies to secure your home from indoor air pollution. Let’s take a look at their air filtration technology.
3-Stage air filtration that removes 99.9% air pollution
An air purifier’s efficiency depends on the type and number of filters it uses. Our air purifiers use a 3-stage air filtration process to remove almost all types of dust particles, dander and volatile organic compounds from the air. Here is how the process works.
- A pre-filter removes PM10 and larger particles such as pet hair and dander from the air. It is washable & improves the life of the other filters as well.
- The high efficiency particulate air (HEPA) filter removes PM2.5 particles, virus, bacteria and other microscopic allergens from the air.
- Lastly, the patented HiSivTM filter absorbs VOCs (volatile organic compounds) and other harmful gaseous pollutants.
The HiSivTM air filtration technology consists of Zeolites which absorb organic compounds and certain mineral molecules in gaseous state. Used successfully in hundreds of commercial systems for drying & purifying liquids & gases, Zeolite molecular sieves are universally applicable adsorbents in the process industries.
Zeolite sieves are made from hydrated aluminosilicates which can absorb liquids and gases. Since these Zeolites are synthetically created, their pores can be adjusted for selective absorption of volatile organic compounds.
High clean air delivery rate (CADR)
We offer a range of air purifiers with CADR (Clean air delivery rate) of 210 to 700 cu m/ hr. that cover a room size anywhere between 250 sq. ft. to 1050 sq. ft. Courtsey a unique design, Our air purifiers have a 3D Air Flow – which allows air to enter from the sides and bottom – releasing purified air from the top to ensure optimum air circulation.
High-quality air filters that last up to 3,000 hours
The HEPA and HiSivTM filters used in our Air Purifiers last up to 3000 and can be easily replaced at home, without any professional expertise or tools. Considering 8 hours of usage in a day, the filters need to be replaced every 12 months, but these figures are subject to the ambient air quality in your city or home.
Child friendly, anti-fall design
Our air purifiers do not have any sharp edges and have an anti-fall design with zero exposure to filters that ensures there is no risk of injury to young children in home. The latches are also protected and cannot be opened by children. Moreover, there is a child-lock on the touch panel to minimise tampering by curious children.

Indoor air pollution is one of the leading causes of health issues in the Indian sub-continent. The deteriorating air quality inside homes is mostly affecting women and children as they spend most of their time indoors. In urban city centres, the problem is made severe by pollutants from vehicular exhaust and industrial emissions. These hazardous particles can stay indoors for long periods of time without getting noticed.
The thing about air pollutants is that they can be hiding in plain sight. The particles that causes air pollution are so small that it is almost impossible to see them with naked eyes. But this invisibility also makes them all the more harmful for unsuspecting homeowners and office goers.
If you are also concerned about the rise in air pollution, here’s a list of the top ten sources of air pollution inside your home or office.
Carpeting & Upholstery
Carpets, curtains and velvet upholstery in homes and offices are the most common hiding places for dust and particulate matter. In damp conditions, these materials can also become a haven for bacterial and fungal growths, often causing a persistent odour.
Electronic Equipment & Plastics
Products made from a certain type of plastics also emit harmful elements that can cause hormonal dysfunction. Generally, Polyvinyl Chloride based plastic is known to emit phthalates, which are not good for the health of children, young adults and the elderly. That’s why checking the products for plastic quality is always advised.
Kitchen Stove & Cooking Activities
While natural gas is a relatively cleaner fuel than burning coal or using kerosene stoves, there is still a slight chance of carbon monoxide emissions as a by-product. Prolonged exposure to CO can cause headaches and sustained fatigue. Sometimes, cooking activities can also produce nitrogen dioxide, which is an irritant and can trigger underlying respiratory problems like asthma.
Certain Paints & Varnishes
Giving their home a coat of fresh paint is on the yearly bucket list of most people. However, certain paints can emit volatile organic compounds upon drying, especially enamels. The same is true for varnishes and vinyl coatings found on furniture and wood objects. Exposure to these sometimes triggers headaches and nausea in people.
Adhesives in Furniture and Electronics
Some adhesives make use of formaldehyde, a known carcinogen. Furniture and electronics using such adhesives may release formaldehyde fumes over time. Generally, the amount of these fumes is too low to be a major health concern for homeowners. But it may be the of cause allergic reactions in people who are working in furniture shops or electronic stores.
Pet Dander & Hair
We love our pets. These little furballs of joy always manage to turn our day around with their antics. But for a healthy home, pet care is very important, something which gets ignored in Indian homes. Pet hair and pet dander float about unnoticed in the ambient air and can often trigger allergic reactions for asthma patients or people with other respiratory syndromes.
Dusting & Housekeeping Activities
Believe it or not, the way we clean our homes also matters. Using brooms generally unsettles the micro dust particles and throws them up in the ambient air. In time, these suspended particles either settle down or gets inhaled by unsuspecting members of the household.
Smoke from Incense Sticks
Yes, even that. Light up an incense stick and hold it below a piece of paper. After some time, the smoke from the incense stick will start discolouring the paper. The carbon and chemicals present in the smoke cause this discolouration.
Broken CFLs & Tube Lights
Compact fluorescent lights are present in almost all homes and offices. While these lights are a viable alternative for bulbs to save energy, accidentally broken CFLs can emit mercury. Mercury is a neurotoxin – albeit in tiny amounts.
Pesticides, Disinfectants & Cleaning Agents
The chemicals we use to kill household insects and fungal growth also cause air pollution. If your home does not have proper ventilation, the chemical fumes can remain indoors for quite a while. Prolonged exposure to these elements can irritate eyes, nose and throat. In severe cases, you may need to see a doctor as well.
Chemicals and smoke particles released in the air by smoking cigars and cigarettes remain in the air for a long time. If you smoke or there is a family member who does, it can cause passive smoking among others in the house.
Remedies for Indoor Air Pollution
Here are some simple life hacks that can help you get rid of indoor air pollution.
- Vacuum your carpets and upholstery regularly instead of leaving them for seasonal cleaning sprees.
- Do not place electronics in small enclosures, which may cause them to heat up and release more of the harmful plastic emissions.
- Use a chimney or exhaust fan for the kitchen to remove carbon monoxide and nitrogen dioxide from accumulating in the ambient air.
- Allow paints and varnishes to dry off properly before moving into freshly painted rooms or using refurbished furnishings.
- Keep your pets groomed and make sure that you are not missing your vet appointments to keep them healthy. It will reduce the amount of hair and dander they shed.
- Use microfiber cloths and mops for dusting and daily housekeeping. These materials absorb the finest dust particles instead of releasing them in the air.
- Clean up broken CFLs and tube lights as quickly as possible and ventilate the area.
- Avoid smoking indoors for the benefit of yourself and others in the house.
- Close off the area where you are planning to use pesticides or insect repellents. Make sure the area is cleaned up and ventilated before allowing kids back in.
Buy Air Purifiers for Home & Office
While the steps mentioned above will help you clean up the indoor air to a certain extent, they are no longer enough for excessively polluted urban environments. The rise in environmental air pollution in metro cities like Delhi, Bangalore and Chennai has made it difficult for homeowners to keep their indoor air clean. To do that, you need special care and products like indoor air purifiers.
High-quality home air purifiers make use of HEPA filters which can remove particles 2.5 times smaller than the width of a human hair.
We hope this blog helped you in better understanding indoor air pollution and will help you in taking care of your health and wellness.
Air pollution has become a public health concern all over the world. Large scale industrial activities and vehicular emissions are the major causes of environmental air pollution, especially in developing countries like India. However, in recent years, indoor air pollution has emerged as one of the leading reasons for health issues in Indian metro cities.
Seemingly harmless stuff can cause indoor air pollution such as pet hair, cooking smoke, adhesives in household furniture and electronic equipment.
Toxic microparticles spread by air pollution can enter our lungs through the nasal tract and cause various health issues which can be as severe as cancer.
Here are Some of the Common Diseases Caused by Indoor Air Pollution.
Lung Diseases and Respiratory Problems
Conditions such as asthma and chronic obstructive pulmonary disease (COPD) can be caused or triggered by rising levels of air pollution. In several Indian metro cities, air pollution is the primary trigger for breathing ailments in children and the elderly.
While previously lung cancer was associated with those who smoke excessively, new evidence suggests that indoor air pollution can also be carcinogenic. Adhesives and chemicals used in furniture and computer equipment can release formaldehyde fumes, which are a known cause for cancer. It can be especially harmful to people who live or work in congested spaces, with little or no ventilation.
Breathing in polluted air for long periods can increase the risk of heart diseases. Harmful air pollutants such as carbon monoxide, nitrogen dioxide and ozone can get mixed in the bloodstream and cause cardiovascular disorders. Particulate Matter is another pollutant that severely impacts the nervous system and cardiovascular activity.
Affects Pregnant Women and New-borns
Indoor air pollution can also have adverse effects on the health of women during pregnancy. The unborn child can suffer from a weaker immune system and may have a lung disorder upon birth. Newly born children also get affected by air pollution as they breathe in more air than adults during their formative years.
Shortened Life Span
Not necessarily a disease, but air pollution is also having an impact on a person’s general health and wellness. Multiple studies point out that the lifespan of a person living in a metro city like Delhi is about three years less than a person living in a cleaner rural or urban environment.
Safeguarding Yourself from Air Pollution
While we wait for the world at large to come at a consensus about dealing with air pollution, there are a few things to protect ourselves from air pollution.
- Wear an air pollution mask that filters particulate matter when going out.
- Travel in closed transportation to shield yourself from the carbon pollutants flying about in the air.
- Make sure that your house has proper ventilation. Install a chimney or exhaust fan in the kitchen to remove the gases released from your stove unit.
- Buy air purifiers for your home. Air purifiers with HEPA and activated carbon filters are the best at removing pollutants like PM2.5 particles and bacterial, viral and chemical contaminants.
- Get a car air purifier to secure your vehicle’s cabin from dust, Particulate Matter and gases like carbon monoxide.
About Air Purifiers
People are increasingly becoming aware of the risk posed by air pollution and have started opting for home air-purifying solutions. More people are now looking for home air purifiers online in comparison to when the products first went on sale.
Now, you can also refer to our air purifier buying guide to get the best home air purifier for your home and office.

Heart diseases also known as cardiovascular diseases are among the most common health disorders in our country. While the most common causes of heart diseases are hypertension, rising cholesterol levels and smoking, recent studies have indicated that airborne pollutants can also contribute to serious, and sometimes fatal, cardiovascular damage. Where the former problems, that cause heart diseases, can be addressed through a healthy diet and regular exercise, the latter problems of air pollution have no such workaround.
Common Heart Problems Caused by Air Pollution
When you breathe polluted air, you also breathe in particulate matter which can enter your bloodstream and block arteries or restrict the supply of Oxygen to the heart. These conditions can cause lasting damage to your heart.
- Very fine particulate matter also known as PM2.5 is a major cause of air pollution in Indian metro cities. Rising PM2.5 levels can cause artery blockage (ischemic heart diseases) or trigger a congestive heart failure.
- Researchers have found that the presence of nitrogen oxide along with fine particulate matter can also trigger heart problems. Cities having higher nitrogen oxide concentrations have four times higher cases of heart related ailments.
- Exposure to air pollutants can also cause chronic cardiovascular dysfunction. This also means, people living in smaller cities with less air pollution might also get affected by rising levels of air pollutants – albeit over a longer period and sustained exposure.
The health problems caused by air pollution are a significant challenge for the healthcare sector – especially in countries like India, where pollution is more severe than it is in developed countries. Moreover, harmful pollutants can also enter homes and mix with indoor air pollutants – that is the reason more people are buying home air purifiers these days. Our products have a combination of Pre-filter, HEPA and patented HiSivfilters which are the best indoor air filters available in the market today.
Apart from buying an air filtration system for your home or office, certain precautions such as wearing face masks and avoiding travel in open vehicles can also reduce the health risks posed by air pollution significantly.

Home air purifiers are becoming a must-have home appliance due to rising air pollution. The problem of indoor air pollution is more severe in metro cities such as Delhi, Mumbai and Bengaluru. Indoor air pollution can have an adverse effect on overall health. This realization has prompted people into investing in air purifiers for home.
There are several brands selling air purifiers in the market, both online and offline. Branded communication can often confuse buyers with varying claims of features and effectiveness. In this post, we try to demystify the basic features that you should look at while making a purchase.
There are two types of air purifier technologies in the market – active and passive. Active air purifiers release ions to charge the dust particles in the air by releasing negative ions in the air. These particles stick to surfaces like ceiling, walls, floor, and furniture. Thus, active air purifiers do not remove the dust and pollutants from your house. They just stop them from being airborne. Also, the ionization process can sometimes release Ozone as a byproduct. Ozone is a harmful gas for humans to breathe and may cause health problems in the long run (Ref).
Passive air purifiers, on the other hand, use the simpler concept of air filtration. These air purifiers have filters inside them. The in-built fan sucks the ambient air and passes it through these filters. The purifier keeps on repeating the process till your whole room or office space has clean air.
Now that you know about the Air filtration technology, it is time to dive a bit deeper and compare the filters. Cheaper products use simple air filters which are akin to the one used inside your car’s blower. They won’t keep much out aside from some dust and larger particles such as hair and dander.
To be effective, an air purifier must have a HEPA filter at the minimum. HEPA stands for high-efficiency particulate arrestance. The HEPA filter can trap particles as small as 2.5 microns (PM2.5). Take note though that the quality of HEPA filters also varies by brand.
A carbon filter is also used in top-quality air purifiers to protect against gases and VOCs. The carbon filter absorbs and nullifies gaseous substances and removes foul odors. Once again, companies have developed their own activated carbon filters. Our patented HiSiv technology comes from the background of usage in petrochemical plants where the harmful gases are much higher in concentration. This technology delivers much higher cleaning efficiency for these harmful gaseous products, while it does not take away moisture from your air, unlike an activated carbon filter.
Since filters require replacement after a certain time, companies also use pre-filters. A pre-filter is used to trap larger particles, thus increasing the life of HEPA and carbon filters. So, when buying an air purifier for your home or office, make sure you compare the number and quality of the filters.
Clean Air Delivery Rate:
CADR is the speed at which an air purifier can clean the ambient air inside a particular space. The higher the rate, more effective is the cleaning. For your reference, a CADR of 300m3/h can clean a room of 450 sq. ft. in around 15 minutes depending on the ambient air quality.
Since an air purifier is going to sit in your home or office, it is also important to check for noise levels. Some air purifiers come with fans which are not optimized for silent operation. Buying such a product can cause constant humming noise inside your home or office. Acceptable noise levels for air purifiers range between 20dB to 55dB.
An air purifier mainly needs replacement filters for its seamless functioning over the years. Select a purifier which has its filters available easily.
Our home air purifiers use a 3-stage air filtration technique to ensure that air pollutants do not affect your family and loved ones.
Here are the filters used in a home air purifier:
Pre-filter: A washable mesh filter that removes PM10 particles and larger dust or hair particles from the incoming air. The pre-filter is needed for increasing the life of more advanced air filters, namely HEPA and activated carbon filters – inside the unit.
HEPA Air Filter: High-efficiency particulate air filter is the most effective air filter for removing microscopic dust and debris which very small and invisible to the naked eye. It can remove particles that are 2.5 times smaller than the width of a human hair, also known as PM2.5 particles.
HEPA air purifiers are quite common these days but the quality of the filter also matters when you are buying a home air purifier with this technology. We use the highest quality HEPA filters in its home and office air purifiers. These HEPA filters can remove 99.9% of the fine dust particles from the air.
Now to the filter we wanted to talk about in this post.
Activated Carbon Air Filter
We use a patented filter known as HiSivTM in their home, office and car air purifiers. It is an activated carbon filter. This is the most advanced air filter in our list, so let’s have a look at function and features of an activated carbon filter.
- What is an activated carbon filter?
These air filters are made from small pieces of charcoal – generally in a granular or powdered block form – which is extremely porous. The pores in these carbon blocks can absorb a very large number of contaminants.
As the polluted air passes through these filters, organic and gaseous compounds are trapped within the carbon tunnels. Our special activated carbon filter is treated with additional chemical compounds to make it even more effective than a regular charcoal air filter.
- Things removed by activated carbon filters
Charcoal filters remove harmful gases like kitchen smoke, cigarette smoke, carbon monoxide, nitrogen dioxide, formaldehyde fumes and other volatile organic compounds from the indoor air.
Moreover, activated carbon also removes bacterial, fungal and viral elements from the air and takes out foul odor. So, if your home or office is near an area where odours and toxic gases from outside regularly enter the indoor environment, our Home Air Purifier with HiSivTM filter can be a useful investment for you.
Life of Air Purifier Filters
We promise up to 3000 hours of usage before the air purifier filters need replacement. The change, however, may depend on the levels of pollution in your particular case. If you are living in a highly polluted area like Delhi NCR, you may have to keep a regular check on your air purifier filters to ensure that proper maintenance and air filter replacement is done on time.
You can also refer to the high accuracy pollution sensor on your air purifier which indicates indoor air quality and lets you know when you need an air purifier filter replacement.
