Considering Improving Your Home’s IAQ With UV Lights?

Considering Improving Your Home's IAQ With UV Lights? Depending on factors in your home – including unique circumstances that help create dirty indoor air and threaten the health of family members – you may want to consider escalating efforts to improve indoor air quality. One proven method is to install UV lights, also known as a germicidal ultraviolet light system.

These systems target and eliminate many of the airborne bacteria, viruses and other micro-organisms that pollute and contaminate indoor air.

Your furnace filter can screen out a good portion of non-organic particulates in indoor air, including household dust, while dedicated air cleaners can remove even more. Yet, for the task of neutralizing and eliminating micro-organisms – the particulates most responsible for triggering respiratory illness and allergies – UV lights are best.

Ultraviolet light systems have two very different applications in residential HVAC systems, and both are effective at improving indoor air quality. They include:

In-duct installation

Installed in your home’s air ducts, the system shines UV light on household air circulating through ductwork on the way to registers. As the air repeatedly flows past the UV lights, the rays of light gradually scrub micro-organisms from the air. The process is a bit more complex than this, but essentially the ultraviolet light breaks down the DNA in the microscopic organisms.

Coil installation

In the second method, UV lights can be positioned to shine on the heat-exchange coils of your air conditioner or heat pump. The damp, dark environment of refrigerant coils provides a hospitable breeding ground for micro-organisms such as mold and bacteria. Air passing across the coils is vulnerable to contamination from accumulated germs breeding in this area.

In homes that succeed in maintaining indoor air quality, UV light systems often work in combination with other air-cleaning technologies. These might include HEPA (High Efficiency Particulate Air) filters and electrostatic filtration. With any air-cleaning strategy, regular maintenance is necessary. For example, UV lights should be switched out on a regular basis (check the manufacturer’s recommendations).
