Best air purifier for bacteria and viruses in 2022

As a homeowner, you may feel like your house is tidy once you vacuum the floors and carpets and dust the countertops. While that may help to reduce the amount of dust in your home, there still exists flu, bacterial, and viral particles lingering on the surfaces and in the air.

The worst part is that you and your family will be exposed to these viruses and bacteria on a daily basis. With the high cost of medical care in the country, you don’t want infections to take away your happiness and money.

That is why you need a way to disinfect the air and surfaces in your home. One of the most effective ways is by using the best air purifier for bacteria and viruses.

Why not use a disinfectant?

While disinfectants help to remove particles that land on countertops, floors, and faucets, they do not get rid of those that linger in the air. The air in your house must also be clean to avoid ailments caused by bacteria and viruses.

Air purifiers are exceptionally good at disinfecting the air. However, this doesn’t mean that you should stop using disinfectants on surfaces.

Things to consider in the best air purifier for bacteria and viruses

If you are on the market for a bacteria or virus killer, here are some things to look out for before purchasing it.

  • Antimicrobial agent: Buy an air purifier that has an antimicrobial agent. That is crucial because most of these units have filters that only trap bacteria instead of killing them. To prevent the machine from becoming a breeding ground to bacterial growth, it should have an antimicrobial agent that will inhibit the growth of bacteria.
  • UV-C Light: Air purifiers only remove bacteria that are 0.3 microns in size. Since viruses can range from 0.004 to 0.1 in size, buy a unit that has UVC-light. It will be useful for killing airborne viruses.
  • Size: Buy a machine that can cover the entire size of a room you want to purify. Ideally, it should not be less than 200 square feet in size.
  • Ozone-free: It is not helpful to buy an air purifier that produces trace amounts of ozone. Ozone can be harmful to human health. If you get one that emits ozone, do not use it while you or others are in the house.


If you are looking for the best air purifier for bacteria and viruses, consider one that features a True HEPA filter and UVC-light. The HEPA filter will remove airborne particles or bacteria as small as 0.3 microns, and the UVC-light will kill viruses as small as 0.004 microns. Also, choose a unit that covers the entire size of your house. It should purify at least 200 square feet of room space.
