The Original Fresh-Aire UV Light System

The Fresh-Aire UV AHU Series 1 germicidal UV light system is installed in the central air system where it sterilizes airborne viruses and bacteria. It also suppresses mold growth on the cooling coils and surrounding areas while generally improving indoor air quality throughout the home. It is available in single & dual lamp configurations for comprehensive UV light disinfection.

Heavy-duty Power Supply

The auto-switching 120-277 VAC power supply is completely sealed for mounting in wet locations.

Coils with Mold

UV light keeps coils clean

What AHU Series 1 Does

Clean Coils

Mold thrives in the cool, moist interior of the central air system. UV-C light is proven effective at sterilizing mold and other biological contaminants. Moldy coils shorten the life of the air system and waste energy by reducing efficiency. UV-C light kills the mold and reduces the need for system maintenance.

Indoor Air Quality

According to the EPA indoor air pollution is often five times worse than outdoor and represents a significant health risk. AHU Series 1 improves indoor air quality by sterilizing mold, bacteria, viruses, and allergens from the air as it cycles through the central air system.

How AHU Series 1 Works

Germ-Killing Power of UV-C Light

For over a century scientists have known about the germ-killing properties of UV-C light. Because this frequency of light is filtered out by the Earth’s atmosphere microorganisms have no defense against it. It works by scrambling their DNA which prevents them from reproducing.

DNA Scramble

UV-C light works by penetrating the cell walls of microorganisms and scrambling their DNA. This prevents them from reproducing.
