Too much ultraviolet light can have a negative effect on skin, which is well known. Too much UV light from the sun (which contains the harmful UVA and UVB type rays) which have been implicated in many types of skin cell abnormalities and skin cancer. At the same time, absorbing some UVB rays from sunlight is a very good thing, as it converts vitamin D3 in our skin to its usable form, which is important for immune system and better health in general. And on the list now under great benefits of UV light is improving indoor air quality.
UV light has been used for years to sterilize and disinfect lots of things in medical and laboratory settings. In fact, UV light can sterilize a surface within just a few seconds of exposure. As a result, researchers found that UV light in air conditioning ducts is very effective for killing mold or viruses floating in the air. With enough UV light, scientists found that they got a consistent 95% plus kill the first time the air passed by the bulbs. And we say ‘bulbs’ because in those tests, there were two UV bulbs of 36 watt strength. When you have two bulbs at 36 watts, placed 30 inches apart from each other like they did in the laboratory tests, you get a full 48,000 UV light units which is enough to kill over 95% of all strains of bacteria, mold, viruses, even algae.
And while UV light bulbs aren’t ‘air filters’, they do kill the organisms that cause health problems, cause many of them to drop out of the air, and produce OH- ions, which enhance the effectiveness of many air purifier and HVAC filters. UV light used in air conditioning ducts has been so effective that most allergy or respiratory sufferers surveyed say that their symptoms were drastically reduced or eliminated in as little as 48 hours after installation. For anyone with a compromised immune system, or the elderly, a UV system in the air conditioner ducts could make a big difference in their health, since this stop the constant reinfection from airborne bacteria, viruses, mold and other germs.
If you want the best home UV air purification, it’s best to get it from UV lamps installed in your HVAC ducts, mainly because it’s the strength of the bulbs and the fact that all of the air in your home is being sanitized, not just the air in one room (as in a room air cleaner with UV bulbs). Most air purifier UV bulbs are anywhere from 10 to 20 watts and help some, but don’t provide enough light units to kill many species of bacteria, mold, or other germs.
UV light air cleaners are very cost effective for indoor air disinfection, with several high quality two-bulb systems for around $500, which is less than most top-rated air purifiers. Just make sure that whatever UV system you choose that it has two 36 watt bulbs and that they are installed 30-36 inches apart on the output side of your air conditioner. Installing an air conditioner UV light system on the output side allows any pollutants being release from the coil to be sterilized, as well as the air coming into the unit.
