HVAC Mount UV Light Air Purification Systems – A Smarter Choice for Clean Indoor Air?

UV light has been used to sterilize water and other materials in hospitals, laboratories, households, and enterprises for a long time. Many air purifier manufacturers have added UV light as an extra germicidal and musty odor-eliminating measure to their air purifiers. The difficulty is that even if you have numerous air purifiers operating, including UV-light air purifiers, the air still has to get to the purifier to be cleaned. You often breathe unclean air before it can be cleaned. 

This is why, even if you have an air purifier or two running, sneezing, coughing, waking up with a stuffy nose, sinus infections, or that odor you can’t seem to get rid of, don’t go away completely. The odors you detect are most likely caused by live mold spores, live bacteria, dust mites, pet hair/dander, and other pollutants that are still present in your ducts. When the air conditioning (A/C) or heating (HVAC) system is turned on, all of this is blown into the air. Yes, even if you have a good filter/filtration system attached to your furnace/air conditioner, it still blows mold/bacteria into the air because the ductwork after the filter is still loaded with all of these live pollutants—the filter only stops the pollutants in the HVAC ductwork BEFORE the filter. 

So, what’s the answer? Purchase an in-duct UV light air cleaning system that installs directly into your HVAC / furnace or air conditioning system’s ducts. Why? UV light systems installed in HVAC/air conditioning ductwork are highly germicidal (killing over 99 percent of all bacteria, mold, viruses, and other microorganisms), so even if some pollutants make it into your air, they won’t be alive and able to harm you. Installing a UV light air purifier system can even decrease or eliminate the need for an expensive duct cleaning procedure, which is only necessary for the ductwork after the filters (less costly than a complete duct cleaning job). In addition, installing an in-duct UV light air cleaning system costs significantly less than installing three or four air purifiers, and it kills mold, mildew, musty odors, and germs in all of your home’s air, not just one room. Add an allergy-rated filter to your HVAC system (one with a rating of 1500 or above, approximately $20 at Walmart), and you’ll be well on your way to cleaner indoor air. 

When purchasing an in-duct UV light air cleaning system, make sure the bulbs are at least 36 watts—this is the wattage that has been found effective in lab tests; anything less will leave certain germs/mold species alive and is a waste of time, 2) make sure the mounts are made of a non-metal material (such as ABS plastic)—this will prevent rust/corrosion in your air ducts, which can further contaminate your air, and 3) make sure the bulbs and 3) Get a double bulb system if you can—most single bulb systems, even at 36 watts, only provide 24k light units, which is enough to kill most bacteria and mold species, but some bacteria and mold species

require up to and beyond 30k units to kill them; a double bulb system would provide you with two x 24k or 48k UV light units, which is more than enough. 

I highly recommend obtaining a UV Light Air Purification System intended for easy, DIY mounting inside your HVAC / furnace / a-c/air conditioning ducts to help you continuously breathe cleaner, healthier air in your house.
