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 your 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 this 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.
