12 Best Air Purifiers for Bacteria and Viruses

For many years, people only knew air purifiers to get rid of indoor air pollution from cooking fumes, mechanical emissions, and dust, but that’s far from the truth.

Remarkably, air purifiers can get rid of much more, qualifying them to the ‘must-have’ list. They are such a great investment.

So, Can an air purifier trap and kill viruses and bacteria?

Well, yes! Most air purifiers trap and kill bacteria and viruses in the air at the time. High-Efficiency Particulate Air (HEPA) purifiers are particularly effective in arresting airborne virus-sized air elements. Other air purification technologies can kill bacteria and viruses.

Nonetheless, no air purifier can safeguard you from a virus completely. They should, thus, not be used as substitutes for personal hygiene. You should keep up the usual hygiene routines to avoid getting germs into your home.

Not sure where to start? We have selected the top best air purifiers for bacteria and viruses in your home. Besides, we will guide you on what to look out for in the best air purifier for bacteria and viruses.

What to Look for When Buying An Air Purifier for Bacteria and Viruses

Here is a universal truth.

Not all air purifiers can eliminate germs and viruses. It takes a special kind of air purifier to do this. One with either of the following technologies.

Ultraviolet Light

UV-C light is a form of radiation that destroys airborne bacteria and viruses by destroying their DNA. Ultraviolet light kills the germs through the air passing through the light.

When the air is sucked into an air purifier for cleaning, it passes through thru UV-C light on its way out. The radiation breaks the germ’s DNA apart and kills them. The air is sterilized and safe for you to breathe.

HEPA Filters

Most viruses have a diameter of between 0.2microns and 0.4 microns. Some are smaller. For instance, the coronavirus is 0.1microns.

But High-Efficiency Particulate Air (HEPA) filters can only filter particles bigger than O.3 microns? Doesn’t that put coronavirus and other viruses below the size that HEPA filter can trap? You ask.

Well, not necessarily. Research has proven that even particles smaller than 0.3microns have a good chance of being trapped by HEPA filters. This is because such minuscule particles tend to move in random directions, thus encountering the filter fiber as they pass through. As a result, they are trapped just like the larger particles.

Bacteria, on the other hand, ranges between, 0.2 to 10 microns. HEPA filters can easily trap bacteria. However, there is a risk of the filters becoming a breeding ground for these bacteria. If the filters are not replaced as scheduled, the bacteria may penetrate the filter and flow back in the air.

Silver Infused HEPA Filters

As the name suggests, these are HEPA filters that are infused with silver.

You see, silver is a natural antiviral, antibacterial, and antifungal agent.  It forces the reproduction of these pathogens to stop. This makes this kind of HEPA filter more effective.

How this filter works is that the surface has silver nanoparticles. The pathogen’s outer membrane comes into contact with the nanoparticles; their (pathogens) structure is altered. These changes lead to degradation and finally, the death of the pathogens.

Photoelectrochemical Oxidation

Air purifiers with this type of technology can also kill viruses and bacteria. These kinds of filters generate catalytic oxidation effects that break down the germs.
