A replacement filter for fresh air is a filter element that we need when the filter element of our filter gets worn out or blocked after a period time using. The filters in an air purifier are rated for up to 3,000 hours of operation.

• 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 our air purifier. We 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.

• Replacing the Activated Carbon Filter

The second most important part of our 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 us identify an old filter and replace it promptly.

• Washable Pre-Filter

The pre-filter used in air purifiers is meant for extending the efficiency and life of the two main filters. We should check the filter every 15 days for dust and debris to ensure smooth airflow inside the unit. In case the pre-filter gets damaged, we 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. We should keep the area around the air purifier clean so that the unit does not need to do unnecessary air clean-ups.
