Cold and flu season is here and both can really make our days (including our Holidays) just plain miserable. And granted, a lot cold and flu viruses are transmitted during person to person contact, a good percentage of these viruses, unfortunately, often come from the air conditioner ducts. Air conditioner ducts? Absolutely. Think of it this way: we track in all sorts of dust every day we walk into our homes, adding to the dust and particles already there. Dust contains many different bacteria and viruses and this dust is circulated through the HVAC system where a lot of it is stopped by the air conditioner filters.
Most of the smaller particles 2.5 microns and smaller, however, pass right through the filter and out into the duct work after picking up a little moisture from the cooling coils. This moist dust sticks to the inside walls of the duct work, allowing mold, bacteria, and viruses o multiply since they have everything the need to grow–moisture and organic material (any kind of natural particle or fiber). As the air blows by these ‘dust colonies’, some is released into the air and blows right out into our rooms, spreading cold and flu causing bacteria and viruses to every part of our home. This is precisely why UV light air cleaner systems mounted in the duct work can be so effective at reducing or even preventing the spread of colds and flu.
Ultraviolet light air purifiers deliver powerful UV-C light rays directly where these dust, bacteria and virus ‘farms’ are growing and thriving–in the duct. And every time these organisms float past, they’re exposed to the light, which not only destroys their cell structure, but also their DNA, preventing them from reproducing. UV light air cleaners also produce healthy negative ions (OH-, not ozone), which also destroy bacteria and viruses on contact, and do a good job of disintegrating airborne organic molecule that cause various odors in the home. And most UV air cleaners are very economical to operate, using only as much energy as a normal light bulb. Sounds simple enough, right?
So why isn’t everyone installing ac UV lights in their A/C ducts? Well, many people are installing them now because they are finding out how effective UV light can be for reducing and preventing colds, flu, and other illnesses. Some people, however, will say that ultraviolet light air purifiers don’t work very well. The truth is, for cases where people say they don’t work, it usually because 1) the bulbs they are using are not true 36 watt laboratory grade bulbs, 2) they have two or more bulbs that are installed too close together (which nullifies the effect of the extra bulbs), or they have installed the UV light system on the intake side of the air conditioner.
If you buy an ultraviolet light air purifier with at least one 36 watt bulb, and install it on the output side of the air conditioner system, any microbes coming off that wet coil (where many bacteria and mold species grow) will be killed by the UV light before getting a chance to blow out into the rest of the duct work and into your home. If the bulb is less than 36 watts, it simply will not produce enough light units to kill a high percentage of the bacteria, viruses, and mold spores that cause most of the problems. And two or more bulbs less than 30 inches apart causes some kind of cancellation in the light waves that doesn’t give you the full effect that 2 or more bulbs would have.
Placing two bulbs 30 inches apart, however, does double the light units and is very effective–with up to a 99% kill rate for virtually all species of bacteria and mold. And for the record, there is a LOT more research proving the effectiveness of duct mounted HVAC UV light air purifiers than any reports to the contrary, and UV light has been used for decades in the medical industry for disinfection, so we know for a fact that it works.
Just be sure that the UV light air purifier system you buy for your central air conditioner ducts has those true 36 watt laboratory grade bulbs and be sure to place two bulbs, ideally, 30 inches apart in the duct on the output side of your air conditioner. Most people that do this notice a big difference in air quality, better sleep, and less respiratory symptoms within 24-48 hours. That means in 24-48 hours, you’ve killed over 99% of any cold & flu viruses, so there’s a lot better chance that you won’t get sick or if you do, it won’t last as long because you’re not constantly being re-infected by polluted air in your home.
