The Original Low-voltage UV Light Kit 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).

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. 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. UV-C light works by penetrating the cell walls of microorganisms and scrambling their DNA.

This prevents them from reproducing. UV-C light kills nearly all biological contaminants including: Blue-Tube UV "ER", "ST" models 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. air conditioning units for multiple roomsBoth support one or two year Fresh-Aire UV lamps.value of copper in ac unit Note: one and two year Fresh-Aire UV lamps are interchangeable.portable ac unit for mobile home SPECS ▶MANUAL ▶     INFO & IMAGES ▶ About Germicidal UV LampsUV stands for Ultra-Violet light. Ultraviolet light represents the frequency of light between 200 nanometers (nm) and 400nm and cannot be seen with the naked eye.

Within the UV spectrum lie three distinct bands of light: UV-A, UV-B, and UV-C. Longwave UV light (315nm to 400nm), or UV-A, refers to what we commonly call "black light." UV-B (280nm to 315nm), or midrange UV, causes sunburn. Germicidal UV light (200nm to 280nm), or UV-C, is effective in microbial control. Research has demonstrated that within this UV-C band the most efficient frequency for microbial destruction is between 254nm and 265nm. Germicidal lamps that produce the majority of their output in this range will be the most effective in microbial control/destruction. 12,214 posts, read 13,180,715 times 1,416 posts, read 4,245,939 times 15,973 posts, read 30,190,849 times I agree that an ultraviolet light would probably do little to help allergy/sinus problems. Those are typically the result of pollen, pet dander or mold in the air, which ultraviolet light would do little to eliminate. Ultraviolet light is effective in killing bacteria, but would be completely ineffective on pollen and dander, and probably do very little to mold, and even then your allergies would probably respond to the dead pollen and mold.

An electrostatic air filter installed in the HVAC system can help a lot to remove those things from the air, but its expensive and the high quality filters available these days are almost as good. I have used one of these portable Friedrich air cleaners in my house for years, it was recommended by my allergy Doctor and it does help.

When we bought our current house we had a mold issue that was contained to a small area of drywall. We had the drywall replaced and installed the ultraviolet light in our AC system. Since then we have had no issues with mold in the house (we had the air retested). The guy who cleans my AC (not the guy who installed the UV lights) says that the UV lights are very effective.

1 posts, read 31,906 times We had a new AC system put in last summer. The contractor included a UV bulb between the cooling area and the supply fan. It's supposed to kill bacteria and other nasties in the air. My question is "when should I replace the bulb?" Other than the obvious answer "when it stops working" I'm wondering if there's a point where (for whatever reason) it becomes less effective. Is it possible that the bulb could still be putting out visible light after it stops putting out UV, which I obviously cannot see? These things are not cheap (they're around $70) so I'd rather not replace it sooner than I have to. UV lights in both HVAC and water purification systems should be changed yearly. This is also in the Honewell spec sheet for the UV2400: Lamp should be changed 1/year or every 9000 hrs to maintain its Many systems have a timer and will start beeping and/or flashing a light after 1 year to remind you to replace them. It's not that they will just stop working after that time, but that their output is reduced over time and they're built so they have an effective output for a year.
