Mold, mildew and bacteria are three things you don’t want floating around in your indoor air. Yet your HVAC system can easily harbor these and other airborne organic pollutants, many of which can trigger indoor allergies and respiratory problems, including asthma attacks. Keeping your HVAC unit free of these pollutants with the help of UV lights not only maintains the overall efficiency of your system; it helps keep your home healthy and comfortable.
Ultraviolet (UV) light alters the DNA of various biological pollutants, making it impossible for them to grow and reproduce. By deactivating and consequently destroying both airborne and surface biological pollutants found within the HVAC surfaces, UV lights, also known as ultraviolet germicidal irradiation cleaners, improve your home’s indoor air quality. These devices are usually installed downstream of the air filter within the ductwork and upstream of the cooling coil. UVGI systems are also found in portable air cleaners. There are plenty of benefits to using UV lights to preserve your home’s air quality:
- UVGI systems can help reduce your vulnerability to colds, flu, viruses and other wintertime health risks, simply by keeping the air free of bacteria, viruses and allergens.
- These systems also help alleviate strain on your HVAC unit. Dirty air filters don’t let as much air pass through, causing the blower motor to work harder and your system to lose its efficiency. With UV lights ridding the air of many airborne pollutants, your air filter will stay cleaner for longer periods and fewer pollutants will settle within the system.
- UV lights leave no trace radiation, nor do they require any expensive consumables to replace on a constant basis. The UV light itself only needs to be changed at least once a year.
- UVGI systems are designed to work in cooperation with other forms of air filtration, with the latter removing non-organic particles from your indoor air.
