Because of its effect on the skin, ultraviolet radiation has earned a poor rap in some places, and understandably so. Skin cell carcinomas and other malignant growths have been connected to too much UV light from the sun (which contains the dangerous UVA and UVB type rays). Getting some UVB rays from sunshine is also needed for converting vitamin D3 in our skin to useable form, which is important for a range of metabolic functions, the immune system, and many other things. UV light has various advantages in the house, such as improved air quality.
UV radiation has been used to sterilize and disinfect for years in various medical applications, and it does so effectively with only a few seconds of exposure. As a result, researchers discovered that UV light in air conditioning ducts did a number on any bacteria, mold, or viruses floating in the air—in fact, they got a steady 95 percent plus kill the first time the air passed by the bulbs with adequate UV light. And we say ‘lamps’ because there were two UV bulbs in those tests, each rated at 36 watts. When two 36-watt bulbs are set 30 inches apart, as in the laboratory experiments, they produce a total of 48,000 UV light units, which is enough to destroy over 95 percent of all bacteria, mold, viruses, and algae types.
While UV light bulbs aren’t ‘air filters,’ they destroy the organisms that cause health problems, cause many of them to drop out of the air, and release OH- ions, which help many air purifiers and HVAC filters work more effectively. Most allergy or respiratory sufferers surveyed report their symptoms were dramatically reduced or eradicated in as little as 48 hours after UV light
was installed in their air conditioning ducts. A UV system in the air conditioner ducts could major impact the health of anyone with a weakened immune system or the elderly since it prevents airborne bacteria, viruses, mildew, and other pathogens from reinfecting them.
It’s ideal to receive UV light from UV lamps installed in your HVAC ducts if you want the best air quality benefits from ultraviolet light, largely because of the power of the bulbs and the fact that all of the air in your home is sterilized, not just the air in one area (as in a room air cleaner with
UV bulbs). Most air purifier UV bulbs are between 10 and 20 watts and help to kill some bacteria, mold, and other germs, but they don’t give enough light units to kill many bacteria, mold, or other germs.
Simply ensure that any UV system you purchase has two lights that are spaced 30-36 inches apart on the output side of your air conditioner. By installing a UV lamp air purifier system on the output side, any contaminants released from the coil and the air entering the device can be sterilized.
