Home UV air purifier
for bacteria and virus
A home uv air purifier focuses on a difficult, yet important area:
Stopping some of the tiniest airborne particles, viruses, along with some bacteria and germs.
Most standard filtered air purifiers and many electrostatic air purifiers (especially if the collection plates aren't clean) can't trap these tiny particles.
That's when ultraviolet light comes into the picture.
What does UV have to do with anything?
Basically, rays of ultraviolet light will break down the DNA and RNA of the microorganism, sterilizing them and stopping them from reproducing and expanding.About the purifier
Not every UV air purifier is created equal. Effectiveness can vary greatly.Two critical things have to happen for a UV air purifier to be effective. It must:
- have a high enough dosage to damage the microorganisms in the air
- expose the air to UV light for a long enough period of time to give a full dose
Always in conjunction with ....
Critically, it's important to note that home uv air purifiers combine their UV rays with traditional air purifying technologies. Traditional HEPA filters are popular, though some electrostatic models also have UV systems.Keep in mind, the lower the fan speed and greater the resistance to air flow, the more dosage of UV rays the particles will absorb and the more effective it will be. But that also means fewer air changes for the room so less overall air cleaning.
One approach is to have UV rays bathe a HEPA filter, which increases the amount of time particles are exposed. But longterm UV radiation can also shorten the life of the filter, something to consider.
Choosing a technology
Both filtered and electrostatic air purifiers with UV systems will work for general use.Return to home
