Make-believe summer lasts for a minute or two as kindergarten children in sunless Lovozero bathe in ultraviolet light. Brief exposure to UC radiation provides the children with vitamin D, normally supplied by sunlight. The “sunshine vitamin” strengthens young bones.and keep air sterilized and clean … free of virouses

Why Ultraviolet Light?

Kill Germs With Light

For over a century scientists have known that certain frequencies of light have a devastating effect on microbial life. We now know that exposure to ultraviolet light in the range of 254 NM to 850 NM (UV-C band) disrupts the DNA of micro-organisms thus preventing them from reproducing, thereby effectively killing them.

UV Light – A Well Established Disinfection Technology

UV light disinfection is now widely used in hospitals and laboratories to sanitize instruments and work surfaces and to prevent the spread potentially lethal airborne infectious diseases. The technology is used by the food industry to sterilize food before packaging and water treatment systems large and small now incorporate UV light as a chemical-free means of purification.

A Cleaner Air Handler

Installation of a germicidal UV light inside the air handler inhibits the growth of mold there which saves energy by allowing the system to operate more efficiently. A cleaner system also requires less maintenance.

Germs in the Air You Breathe

Like it or not the indoor air you breathe has a lot of stuff in it that you don’t want. Like viruses, bacteria, mold, mildew, and allergens. Some are only annoying, others can make you sick. Because air passes repeatedly through your HVAC system (in fact many microbes like the cool dark damp interior of the system) this is the ideal place for germs to multiply and spread throughout the house.

A Whole-House UV Air Purifier – The Best Defense

Because it works inside your central air system a whole-house UV air purifier is able to intercept airborne pathogens and destroy them as they pass by. As air cycles through the system it passes by the UV light many times exposing and re-exposing airborne microbes to it’s sterilizing effect. this has proven to be a safe, economical, chemical-free way to significantly reduce airborne contaminants indoors.

UV-C Light

The “germicidal range” of UV light is approximately 254– 850 nm, with a peak germicidal effectiveness at 254 nm.
