Pure Air Systems 

UV Air Purifier Advantages :
Fights germs, the anti-microbial germicidal effect disinfects the air, kills germs, bacteria, viruses, mildew, mold spores such as stachybotrys and black mold, etc. as they circulate through the ducts and pass through the UV lamps.
Helps stop the spread of diseases and sickness.
A short wave (UV-C) kills or de-activates bacteria, viruses and other primitive organisms, even if the organisms have become immune to other disinfection methods.
Stops Mold and Bacteria growth inside your central air conditioning system. No more mildew and moldy odor from your air conditioner.
Eliminates odors, makes the air in your rooms smell fresh and clean while producing ZERO ozone.
Destroys VOC's (volatile organic compounds) such as formaldehyde.
Eliminates the need to EVER clean the mold off your cooling coil (evaporator coil) again. Helps decrease cooling costs by keeping the cooling coil from plugging up with mold and gel.
ELIMINATES the need for periodic duct cleaning, by keeping your ductwork clean and dust-free inside.
Generates safe and highly effective negative hydroxyl ions, the natural compound that scrubs pollution from the earth's atmosphere. 
Hydroxyls and hydroxyl radicals are formed when the UV-C from the sun strips  hydrogen atoms from water molecules (H20) forming hydroxyl (OH)-. 
These helpful negative hydroxyl ions are circulated out of your cooling and heating vents and into your living space by your central air conditioner's fan or blower. Creating a self contained evironment in your house.
