Blue-Tube UV is the single most popular germicidal UV light product for HVAC systems in the world. Home owners breathe easy knowing that the air their family breathes is protected by this proven technology. Blue-Tube UV is the simple, safe, and effective way to keep your air system clean and improve indoor air quality.
Blue-Tube UV features a number of patented innovations from Fresh-Aire UV. The original low-voltage UV light kit for HVAC has been updated to include a magnetic mounting bracket and now has a 110-277 VAC high-voltage power supply option. Choose one or two year lamps.
We are so confident in the quality of our design and manufacturing that this product comes with a lifetime warranty on all parts except the UV lamp (which needs to be replaced every one or two years depending on model).
Central AC System with Blue-Tube UV light installed
Mold thrives in the cool, moist interior of the central air system. Blue-Tube UV 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. Blue-Tube UV kills the mold and reduces the need for system maintenance.
According to the EPA indoor air pollution is often five times worse than outdoor and represents a significant health risk. Blue-Tube UV improves indoor air quality by sterilizing mold, bacteria, viruses, and allergens from the air as it cycles through the central air system.
For over a century scientists have known about the germ-killing properties of UVC 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.
UVC light works by penetrating the cell walls of microorganisms and scrambling their DNA. This prevents them from reproducing.
UVC light kills nearly all biological contaminants including:

Blue-Tube UV is available with two power supply options: ER models are low-voltage 18-32 VAC and ST models are line-voltage 120-277 VAC. Both support one or two year Fresh-Aire UV lamps.
Note: one and two year Fresh-Aire UV lamps are interchangeable.
