why use an allerair ultraviolet air purifer?UV light sterilizes indoor air. It eliminates transmittable agents like viruses and bacteria. It is often used in hospitals and daycare centers, where the risk of contagion is high. High-tech laboratories, clinics and isolation wards have all benefited from UV sterilization. The UV light's germicidal properties adapt themselves to many different targets. UV light alters the DNA structure of microscopic organisms, rendering them unable to reproduce. AllerAir units use safe, shortwave germicidal UV-C light, different from the UV-B light which comes from the sun. Germicidal UV-B light is also much safer than ozone, which is used by other air purifier manufacturers. Health officials warn that inhaling ozone, the principal element in smog, can be extremely harmful.
