The EPA states that indoor air can be up to 70 times more polluted than the outdoor environment. One major reason is because the HVAC duct work is full of airborne germs, harmful particles and contaminated by-products. Ultraviolet disinfection is a guaranteed solution which involves the installation of UVC germicidal lamps inside the ducts of your heating and air conditioning system. This provides continual UV purification while re-circulating clean air throughout your home or facility. Our in-duct and upper air UV purifiers sterilize 99.9% of pathogenic microorganisms in the air. The specialized application of germicidal UV light on the coils also eliminates microbial growth from the coil and drain pan.
