Which Air Purifiers Kill Viruses Bacteria and Germs?

There are many air purifiers that claim to kill viruses and bacteria, but not all of them are effective. Some air purifiers use UV-C sterilization, which is a powerful germicidal light that can kill viruses and bacteria.

Other air purifiers use photocatalysis, which is a process that uses light to break down organic matter and kill viruses and bacteria.

How Does an UV Air Purifier Kill Germs, Bacteria and Viruses?

UV-C sterilization is a process that uses ultraviolet light to kill microorganisms. The UV-C light breaks down the DNA of the microorganisms, rendering them unable to reproduce. Photocatalytic oxidation is a process that uses UV light to break down organic matter.

The UV light activates a catalyst, usually titanium dioxide, which causes the organic matter to oxidize. This process also produces ozone, which is a powerful disinfectant.

Things to Consider When Buying an Air Purifier for Viruses and Bacteria

As I said before, there are many brands of air purifiers are available in the market. And all the air purifiers have a good feature. So it is difficult to find the best air purifier for viruses and bacteria. You can buy one of these 5 air purifiers but if you are still having trouble choosing a better one. No problem, this buyer’s guide is for you. I am sure that after reading this you can easily understand how to choose the best air purifier for bacteria and viruses. So read this till the end.

Ultraviolet Light

ultraviolet light

You have to keep in mind some points when you are buying an air purifier. That is your air purifier must have UV light or UV-C light and HEPA filter. These are a must when you are buying an air purifier for bacteria viruses.

Why We Should Buy a Uv-c Light Purifier?

UV-C light is specially designed to kill airborne viruses, bacteria, germs, and other harmful pathogens. UV-C light can generate 185-254nanometers germicidal wavelengths to kill bacteria and viruses. It is invented in the twentieth century.

It is a popular and affordable solution for killing bacteria viruses like COVID-19. The Ultraviolet light directly attacks the genetic structure of bacteria and viruses. It reduces their ability to reproduce. From the distance of 6 inches, UV-C light can kill pathogens in just 10 sec.

The UC-C light is mostly used in industries, hospitals, and laboratories as an insecticide. An air purifier needs ultraviolet because filters cannot kill some harmful bacteria viruses. The HEPA filter can kill pathogens but it cannot capture some microorganisms. The UV light can kill all small and large microorganisms.

That’s why the Ultra Violet-C light is the most important in the air purifier. Before you buy an air purifier make sure that the air purifier has UV light technology to kill bacteria and viruses. There are no side-effects of UV-C light so do not worry about that.

Silver-Infused HEPA Filter

The HEPA means the High-Efficiency Particulate Air cleaners. This is a common filter in every air purifier. HEPA is an important filter in air purifiers. It can remove 99.97% harmful airborne germs, virus particles, dust, mold, pet dander, pollen and aerosol particles. The HEPA filter can clean particles as small as 0.3-micron particles from the air.

Silver-Infused HEPA Filter

But there are some concerns about the HEPA filters. It cannot capture some smaller particles, bacteria, germs, viruses, VOCs and other microorganisms. Those are smaller pathogens than 0.3 microns that HEPA air filter cannot capture. Rather than this bacteria and viruses can grow on the HEPA filter.

It does not mean that the HEPA air filter is not helpful. It cleans the air and removes dust, pet dander, pollen and large particles from air. It provides a fresh and healthy environment for your home.

Nowadays customers are finding a new solution for bacteria viruses. Because of this, some HEPA filter comes with silver for bacteria and viruses. Silver is a natural antibacterial and antivirus agent.

Silver nanoparticles suppress the respiration of bacteria. This process reduces bacteria’s cell growth. Because silver is a natural agent it will help to remove bacteria, germs and viruses. And reduce the growth of these pathogens.

Harmful Diseases That Caused by Bacteria and Viruses

You know that bacteria and viruses can cause many harmful diseases in the human body. Here is some list of some harmful diseases caused by bacteria and viruses.

Diseases by Bacteria

  • Pneumonia by diplococcus pneumonia
  • Gonorrhea by Neisseria gonorrhoeae
  • Septic sore throat by streptococcus bacteria 
  • Syphilis by treponema pallidum
  • Tuberculosis by mycobacterium tuberculosis
  • AIDS by human T-cell leukemia virus

Diseases by Viruses

  • Common cold by rhinovirus Chickenpox by the varicella virus
  • Dengue by dengue virus (arbovirus)
  • Influenza by influenza virus
  • Cervical cancer by human papillomavirus (HPV)

What Type of Viruses and Bacteria Can an Air Purifier Remove?

An air purifier uses a True HEPA filter to clean dust, pet dander, and large particle up to 0.3 microns. But it cannot remove bacteria and viruses. Because viruses and bacteria are smaller than 0.3 microns true HEPA can’t capture it.

An air purifier that has UV-C light/UV light or silver infused HEPA filter can easily remove and kill all types of viruses, bacteria and germs. The ultraviolet light is one of the ways to kill all types of viruses and microorganisms. And silver is a natural antibacterial and antivirus agent so it can easily remove germs, bacteria, and viruses.

An air purifier with UV-C light or silver infused HEPA filter is best for viruses. It can remove viruses like corona, colds, rhinovirus, and dengue virus as well.

Final Verdict

All these air purifiers that I have reviewed are the best air purifier for bacteria and viruses as well as germs. Air purifiers are the best solution to remove bacteria and viruses from your home. You can buy any of these air purifiers. But my advice is the Vornado PC0575DC air purifier. If you want a budget-friendly then you can buy a germ guardian technology air purifier.

Just buying an air purifier is not preventing you from bacteria and viruses. You have to keep your room or home clean. Only a product cannot save you from all the problems. You should try your effort. Take care of your purifier change your filter every 6 or 12 months if necessary. It will expand the purifier’s life.
