Best Air Purifier for Viruses/ Best Air Purifier 2021

What is the best air purifier for viruses ?

Air purifiers represent the perfect way to disarm allergens floating in the home, channeling air through a filter before re-circulating it to you in a vastly cleaner form.

Air purifiers have become an obvious for those looking to protect themselves from the virues and bacterial in the air. That’s not surprising. Data shows that air purifiers can filter virus and bacterials. In fact, the EPA now suggests portable air purifiers be used to improve ventilation to protect against viruses:

A more advanced wave of ultraviolet air purifiers is moving things a step on, though, killing viruses and bacteria making their way through the system through UV light and germicidal irradiation.

We are going to test 3 types of air purifiers that have been marketed as best of combating viruses:

Ionizer Air Purifiers:

Ionizer purifiers are another type of air purifier that some have said is best against virues. They work by shooting negative ions into the air. These negative ions stick to viruses, and in turn sticking them surfaces like walls and tables. The science is similar to what makes a balloon stick to the wall.


This is an important point for ionizer air purifiers. Because the ions only move the viruses to walls and tables, the virus is still in the room. Ionizers do not kill or remove the viruses from the air. What’s more, these surfaces could become a means of transmitting of virus.

HEPA Filter Air Purifiers

HEPA filter air purifiers have been around for a long time. And there’s a reason for that. They do a great job of capturing tiny particles, including nanoparticles as well as  particles the size of the virus.

But traditional Hepa filter air purifiers collect instead of destroy virus.

Filters that collect or trap particles and dust rather than destroying them. Airborne particles are much smaller than droplets and can linger in the air for longer. Air currents can also carry them longer distances.


UVC Air Purifiers:


UV-C light air purifiers are effective in killing or inactivating airborne micro-organisms. and contaminants. They can do so by using UV-A, UV-B, and UV-C lights. Conventional UV air purifiers use low-pressure mercury vapor lamps to emit UV-C radiation.

Researchers have found that UV with HEPA filter air purifiers work more effectively when the UV lights are on.

This has shown to have germicidal effects.

In a 2018 study, researchers sought to find out if cleaning indoor air with UVGI lessens contact infections. The study took 12 months, where researchers reviewed data from UV-C devices. What they discovered after the study was a reduction of airborne bacteria in the patient rooms by 42%.

FDA articles proofs that the UVC is effective for virus also:
