Ultraviolet (UV) lights are commonly thought of as dangerous rays. We use sunscreen, for example, to protect ourselves from harmful UV lights when outside. However, there are instances where UV light is used for good. UV-light purifiers are an effective way to rid your home’s indoor air of things like mold, bacteria, and viruses. Here’s how it works: as air circulates through your home, it passes through the UV lights, where living organisms zapped by the light are killed. UV lights are quite effective at targeting these pollutants because the rays go to the core of the organism, where its DNA is targeted and stops the organism’s ability to reproduce (or grow). There are portable UV-light systems on the market that work well to target organisms within a certain square footage or room. For it to be effective, however, you have to be in a closed room and remain pretty close to the system. Connecting a UV-light air purifier to your home’s HVAC system reaps wider results. Your HVAC system is already designed to circulate air throughout the home. As it passes through, drawn in by the air handler, the air also passes through the UV rays. Therefore, the air in your home is cleaned every time it passes through the system, and you get increasingly clean air each time the air circulates through the home. One thing to keep in mind is that UV rays are effective at killing just one class of pollutants. It is not able to rid the air of dust or volatile organic compounds (VOCs), which consists of things like cleaning solutions or paint fumes. If your respiratory system is aggravated by the organisms UV-light systems target, then this is a good technology to incorporate into your home. However, you can find systems on the market that use dual technology to target more than one kind of pollutant. Do you have a clean-air strategy? Can you benefit from using UV lights?
