For many years air purifiers have been heralded as effective tools for relief from out-of-control allergy symptoms, asthma conditions, and chemical sensitivities.

A new wave of germicidal air purifiers has hit the market that not only remove allergens but destroy cold- and flu-causing germs.


Germicidal air purifiers use materials and technologies such as ultraviolet light, natural silver, and sterilizing heat to eliminate airborne pathogens from your space. Many have been independently tested and proven effective against germs that can cause influenza, colds, strep throat, staph infections, and even tuberculosis.

Ultraviolet Air Purifiers

An ultraviolet air purifier uses an internal UV-C germicidal light to kill airborne bacteria, viruses, germs, and allergens as room air moves through the system. The natural ultraviolet light eliminates these pathogens by breaking down their DNA structures and deactivating their reproductive capabilities.

As a result, germs and allergens cannot reproduce and quickly die off. After UV light treatment is complete, clean air is returned to your environment and the process repeats.

We carry a number of reliable, germ-zapping UV air cleaners.

Germ Guardian Air Purifiers and UV-C Air Sanitizers

They’re proven effective in killing more than 99% of airborne germs. A study conducted by the Harvard School of Public Health, an independent third-party testing lab, found that the company’s UV-C technology kills 99.9% of bacteria and viruses that may cause influenza-A, staph, pneumonia, tuberculosis, bronchitis, and meningitis.

Silver-Infused Air Filters

Silver, a natural antibacterial, anti-viral, and anti-fungal agent, is beginning to make its benefits known across the air purifier industry.

According to research originally published in the International Journal of Nanoparticles, silver nanoparticles have a range of negative effects on virus strains and bacteria. Silver can, for example:

  • Attack a cell membrane
  • Suppress a cell’s nutrient transport
  • Interfere with cell division

All are actions that ultimately hinder the reproduction of germs.

Air Purifiers with Silver-Infused Air Filters

Rabbit Air purifiers are well-known for their ability to clear out allergens, odors, dust, and bacteria with multi-stage filtration. It may be little known, but Rabbit Air BioGS air cleaners also feature filters with an anti-flu coating and antimicrobial protection.

The coating is composed of a special anti-influenza agent that has been proven to lower the viral infectivity of certain airborne flu viruses – particularly the H3N2 virus, a strain similar to avian flu.

Air Sterilizers

Unlike ultraviolet and silver-infused air purifiers, air sterilizers use heat to destroy airborne allergens, germs, and other microorganisms.

How They Work

During operation, these systems pull your room air into an extremely hot sterilization chamber where the temperature gets as high as 400 degrees Fahrenheit.

As air passes through the chamber, the powerful heat incinerates allergens, then clean air is then cooled to a comfortable temperature and released back into your environment.

What Air Sterilizers Destroy

They commonly rid homes of dust mites, mold, pollen, and ragweed, as well as bacteria, viruses, and other harmful pathogens.

They’re also very low maintenance since there aren’t filters to replace, which also saves on operating costs.

Popular Air Sterilizer Products

AirFree air sterilizers are capable of killing 99.99% of microorganisms using their unique TSS process of air sterilizing.

AirFree’s TSS process has been independently evaluated by numerous world-renowned ISO/IES 17025 testing laboratories. All the labs confirmed that the technology was 99.99% effective in destroying microorganisms.

Bottom Line

Nothing can replace basic healthy living habits as a method of warding off germs and illnesses. Actions such as washing hands, covering your mouth when you cough, eating a balanced diet, and exercising regularly can help keep your immune system in tiptop shape.

Germicidal air purifiers can supplement these activities and help you enjoy a healthier environment and life.

Disclaimer: Please note that the air purifiers listed in this article do not replace the need for practicing healthy living habits on a regular basis. According to the Centers for Disease Control and Prevention (CDC), actions such as washing hands with soap and covering your mouth and nose when you cough or sneeze can drastically reduce the spread of airborne germs. Germicidal air purifiers should only be used as a supplement to regular healthy living practices. ​
