How often should I change the HEPA filter in an air purifier

Unless you have been missing for the last 3 years, chances are, you’ve heard about air purifiers and HEPA filters.

These purifiers are effective in removing dust, pollutants, mold, bacteria, and more from our homes.

But do you know how to maintain these devices for your safety? According to the CDC as well as other government agencies, air purifiers that use HEPA filters can be effective in removing the COVID-19 virus from the air. So, of course, due to the pandemic, many people invested in these purifiers for their safety. Studies have shown that an air purifier with HEPA filter can remove particles that are 0.3 microns or sometimes less in comparison to a regular air conditioner filter that removes particles that are between 5 to 10 microns in size. While the air purifiers can remove these particles, you’ll also need to do your part to make sure these devices are operating efficiently. It is widely recommended that the HEPA filter should be changed every 6 to 12 months, and carbon-based filters should be changed every 3 months. Over time, the filter will accumulate all the pollutants and contaminants, and naturally, replacing the filters would mean that the air purifier can function more effectively. Of course, if you’re exposed to air that is extremely polluted, it’s recommended to change the filters more frequently. If you own an air purifier that has a built-in filter, it’s recommended to check the filter for debris and clean away particles as they build up. Viruses will be around forever, so it’s best that we do what we can to keep our indoor air quality safe for us to breathe.
