Indoor air quality is one of the most important considerations to homeowners, especially those with family and loved ones who are affected by asthma and other respiratory issues. Unfortunately, a dirty HVAC system can lie at the heart of indoor air pollution. Mold, bacteria and other organic airborne contaminants tend to breed inside of the ductwork, evaporator coils and drain pans of an ordinary HVAC system. Air filtration systems, including ozone generators, only go so far toward keeping indoor air clean and free of microorganisms.
If you’re looking for a viable solution to your home’s indoor air quality needs, you might want to consider ultraviolet (UV) lights. Used in concert with filters, humidifiers and other systems, these lights are effective in disinfecting the air and reducing the prevalence of mold and airborne contaminants in HVAC ductwork and evaporators. Room-to-room UV lamps are available, but those installed within the HVAC systems themselves are the most effective in improving the air quality in your home.
The key lies in the ultraviolet radiation emitted by these lights. UV radiation is normally dangerous, especially without eye and skin protection, but it’s also useful for killing living pollutants. UV radiation’s unique wavelength allows it to penetrate the membrane and nucleus of microbes, breaking the molecular bonds of its DNA and leaving it unable to multiply. This effectively kills off microbial growth, improving indoor air quality while leaving your HVAC system mold-free.
UV lights are relatively inexpensive, compared to ozone generators and other devices that claim to improve indoor air quality. However, these devices should not be a substitute for a professional cleaning of your home’s entire HVAC system.
