What Do UV Lights Really Do For Your Indoor Air Quality

Indoor air pollution is a growing concern for many. In fact, the EPA (Environmental Protection Agency) states that indoor air pollution can be worse than outdoor air pollution. Different forms of airborne germs, bacteria, fungi, mold and mildew are on the increase in indoor environments. These substances all affect the health of household residents and cause a number of health problems. Those with asthma or allergies are more prone to breathing difficulties. Using UV (ultraviolet) light is an effective method for purifying and cleaning the air.

Why is Indoor Pollution Increasing?

The spread of germs, mold and other pollutant inside the home is due to a number of factors. One is how homes are now insulated. Many people keep windows closed for most of the year and this keep the same pollutants circulating throughout the house. Another factor is the airflow in a home. Even the ductwork or drain pans of the HVAC (heating, ventilation, air conditioning) system are a source for the growth of these pollutants. Not cleaning the filters of the furnace or air conditioning system also contributes to poor indoor air quality.

How UV Light Help to Clean Indoor Air

The UV light creates ultraviolet radiation which destroys indoor air pollutants by turning them into harmless substances. Another method for cleaning the indoor air is using germicidal UV lights. Ultraviolet Germicidal Irradiation (UVGI) is a method that uses short UV waves to destroy bacteria, viruses, allergens and pollutants. Also known as UVC, these lights work by breaking down the DNA of mold, bacteria, viruses, mildew, spores and other harmful microorganisms that pollute the air.

The best way to get the UV light is with UV lamps. You can use the UV lamps in a variety of ways. You can use UV lamps in the ductwork of your HVAC system or in the HVAC filtration system. Another method is to shine the UV light on the heat pump of evaporator coils or on air conditioners directly.

Airborne pathogens reduce indoor air quality and increase health risks. You can get cleaner air in your home by using UV lights. Using the lights on an ongoing basis gives you healthier and more breathable air.
