How Does A Germicidal Air Purifier With UV Light Work?
February 20, 2007
Filed under: Air Purifier Types — Administrator @ 12:16 pm
A germicidal air purifier with UV light destroys microorganisms such as:
- germs
- bacteria
- viruses
- molds
As airborne microorganisms pass through the device, an ultraviolet lamp shines UV rays on them. This damages the microorganisms at the cellular level, killing them.
Sounds pretty effective, but also scary doesn’t it? If a germicidal air purifier with UV light can kill microorganisms, what effect does it have on organisms, like pets and humans?
Well, similar damage DOES occur in humans due to UV lighting, but it’s restricted to the skin and eyes. However, reputable manufacturers will ensure that their purifier units do not allow ultraviolet rays to escape. So the UV lights will only sterilize the air that passes through the purifier.
In fact, UV air cleaners are deemed so safe and effective that the US government specifies UV lighting in government facilities to minimize the growth and spread of germs.
What’s more, UV lights are recommended by the Center for Disease Control for use in homeless shelters. UV lights stop diseases like tuberculosis from spreading. What makes this a big deal is that such diseases often develop a resistance to drugs.
Some commercial office buildings also use UV lighting in their ventilation systems to reduce respiratory-related problems (e.g., breathing difficulties, mucus, muscle pain, etc.) in their employees.

Ultraviolet technology is a non-chemical approach to disinfection. In this method of disinfection, nothing is added which makes this process simple, inexpensive and requires very low maintenance. UV-C light is germicidal - i.e., it deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease. As mentioned, Ultraviolet purifiers utilize germicidal lamps that are designed and calculated to produce a certain dosage of ultraviolet light. Here are just a few of the applications…
