UV Air PURIFIER REVIEWS
A Comparison of Top Ultraviolet Air Purifiers
UV-C light can be referred to as germicidal since it has the ability to kill cells by damaging their DNA. In reviewing a variety of independent test results we have concluded that UV lights can be effective against both vegetative bacteria and viruses and UV-C lights are being used more often in HVAC handling units where moisture collects to prevent mold growth.
What you need to know
- To be effective in killing bacteria or viruses the UV-C light must have sufficient contact time.
- If the particles are quickly passing through the air purifier with a high air flow or the UV light is small it will likely not be as effective.
- Consider the use of UV lights near the cooling coils of your HVAC system to prevent mold growth.
Watch out for UV air purifiers that do not also include a HEPA filter as the HEPA filter is the primary technology to remove dust, pollen, mold, bacteria, pet dander, etc. Think of the UV lamp as an accessory to the HEPA but by no means the primary feature to clean your air.

History of Ultraviolet Light: Unlike the other technologies that we review, UV light was not invented but discovered in 1801 by a German scientist. It is called ultraviolet since its spectrum is just beyond what we see as violet. Remember the mnemonic Roy G Biv from school for the colors of the rainbow? Well, ultraviolet is the wavelength that is just after the V.
