Allergies are among the most common chronic conditions worldwide, says the American Academy of Allergy, Asthma and Immunology. Allergens like pollen, dust, dander and mold act as irritants that force your immune system to fight back against the invader. Your heating and cooling can work hard to keep you healthy, but another way to improve your indoor air quality is by installing UV lights in your HVAC system.

Are UV lights in HVAC systems safe?

Ultraviolet light can play a large role in allergy prevention. They work by emitting UV rays that affect the DNA in cells while also destroying the life-sustaining proteins of that cell. This process stops the organism from reproducing, and will also kill it off

You will want to install the UV light where it will be most effective and kill the most mold and mildew. Usually, the UV light should be placed so that the evaporator coil gets the most amount of light. If you have already had mold growth in your HVAC system, then you will want to install your UV light where it shines on the most problematic area.

As effective as UV lights can be in stopping mold and mildew, they will be ineffective against small particles like dust and dirt. Also, the UV lights do not draw objects to them. Instead, they are stationary objects and therefore an organism needs to pass through the light to be affected.

UV lights by themselves still should not be your only method of defense against your worst allergens. You should still pair your UV lights with an air cleaner or air filtration system for the best results.

So, are UV lights in HVAC systems safe? There is proven success of UV lights, helping to reduce problematic molds and pathogens that are found within your HVAC system.
