Can You Use Air Purifiers To Filter Or Eliminate Viruses?

If you have never used an air purifier, you may have no idea if these devices can help remove viruses. Honestly speaking, if you get a simple air purifier, you cannot filter viruses with that. If you want to get rid of it, you should invest in a special unit that uses the right methods to kill viruses. In this article, we are going to talk about different technologies that can help filter viruses. Read on to find out more.

UV Radiation

With ultraviolet radiation, it is possible to eliminate bacteria and germs. But the problem is that you have to direct a UV light for several hours at the source of viruses for complete elimination of viruses.

The good news is that some air purifiers are designed in a way that they direct the UV light to the filter inside the unit. When the virus passes via the HEPA filter, the UV lights destroy it.

Electrostatic Precipitators

This simple method makes use of opposing charges, which increases the virus size. And when the virus becomes heavier, it tends to fall. However, the problem is that this method cannot be used to kill the virus. Therefore, you should invest in an air purifier that generates UV light or heat to kill the viruses.

Ozone Generators

The long-term use of an ozone generator is not good for your health. Some of these units can generate a lot more ozone than you can tolerate. But the good news is that these devices can kill a lot of bacteria and viruses. All you need to do is turn on the generator and get out of the room. Once the generator has done the job, get in the room and open all of the windows.

Photocatalytic Oxidation

According to experts, you may not want to use this type of air purifier as there are questions about the effectiveness of photocatalytic oxidation. According to some researchers, these air purifiers can generate more air pollutants while fighting air pollutants.

HEPA Filters

As for as air purification is concerned, no device can compete with HEPA filters. But the downside is that these filters are not designed to capture viruses or bacteria. The reason is that these toxins are too small and cannot be captured by these filters.

But the good news is that you can purchase a new type of HEPA filter known as HyperHEPA. With this filter, you can remove tiny particles the size of a virus. But there are still some doubts about the effectiveness of these filters.


In short, you can use a good air purifier to filter viruses and bacteria to ensure your indoor air quality is good enough. Hopefully, these tips will help you make an informed decision.
