In 1903, Niels Finsen won the Nobel Prize in Medicine for his use of ultraviolet light in the treatment of tuberculosis. Since then, ultraviolet lights have been widely adapted for all kinds of uses: sterilizing hospitals, sterilizing water, germicidal lamps in food establishments, and even curing nail polish faster. If UV light is so effective, how can it be applied to improving indoor air quality for residential HVAC systems? Will it kill mold and bacteria in HVAC systems? Yes, but you need to understand the priorities of indoor air quality and the types of UV lights available for residential HVAC systems. About 2 years ago, we installed a 19 SEER Lennox XC 21 air conditioner. During our most recent AC service, the technician also installed a TopTech HVAC UV light inside the air handler, which remains turned on 24/7. According to the technician from Engineered Air, HVAC UV lights are very effective at controlling mold inside the air handler. All mold in line-of-sight of the UV bulb will be killed, keeping the coil mold-free.

He also mentioned that several clients with respiratory problems are even able to tell if the UV bulb has burned-out due to reduced air quality. I’ll let you know if I am able to tell. There are two types of UV lights for HAVC systems. Two studies point to the effectiveness of UV light in killing mold and bacteria, one in hospitals and the other in a commercial HVAC system. The TopTech UV stick light bulb is estimated to last 9000 hours, just over 1 year. Replacement bulbs cost about $70. Replace the bulb during each annual HVAC service and maintenance is nearly effortless. The TopTech UV light we installed is rated at 1.1 amps. To calculate annual energy costs, I used these handy calculators For just under $100 per year ($24 electricity + $70 replacement bulb), my family has peace-of-mind knowing that we are breathing the highest-quality indoor air. It seems like a small price to pay. But it doesn’t make sense to install an HVAC UV light unless you’ve followed the indoor air quality priorities.

While HVAC UV lights are effective for killing mold, bacteria, germs and odors, make sure you have completed the indoor air quality basics: HVAC UV lights are an effective means for improving indoor air quality, but only after following the indoor air quality priorities. Install an HVAC UV light and experience healthier indoor air quality.blueair 203 smokestop air purifier review Intense Pure Air Mid-Size Nano Captur Filterhoneywell hepaclean air purifier with ionizer Thanks to 10 years of research and 5 international patents, the Nano Captur technology filter is the only one to permanently destroy Formaldehyde, the most harmful indoor pollutant and a human carcinogen according to the World Health Organization. microlux air purifier manual
