Can Air Purifiers Kill Viruses? Air Purifier Recommendation List

Can air purifiers kill viruses? Many people have been wondering about this, especially during the COVID-19 pandemic. The answer is yes, but to a limited degree. There are many air purifiers that can actually trap and kill viruses. However, it is expected that they are only capable of trapping a small percentage of airborne germs in a typical home.

High-efficiency particulate air or HEPA filters claim to be able to filter down to 0.3-micron particles.

Most viruses have a diameter of 0.02 microns to 0.4 microns. There are some that are bigger. The diameter of a typical coronavirus is around 0.1 microns. That means the size of the coronavirus is well below the size that a HEPA filter can trap.

However, studies suggest that a HEPA filter can still capture such tiny particles. But it probably won’t kill the virus. Even when trapped, the virus may still survive for several hours to days. It will eventually die unless there’s a chance that you remove the filter and release the virus onto your skin or into the air.

An air purifier shouldn’t be your first and only line of defense against the virus. The two most effective ways to prevent you from getting the disease are social distancing and wearing a face mask. Here are some air purifiers recommended by experts.
