How Do I Install Lennox UV PureAire Lamps?

Lennox manufactures air cleaners and filters to purify the air inside a home. PureAire cleaners filter the air and use a fan to blow clean air into your home. These air cleaners have one or two ultraviolet (UV) lights that glow inside in a blue color. UV lights reduce the occurrence of viruses, bacteria, mold and yeasts to protect your family from diseases and sickness. Lennox recommends installing new lamps once a year, as the effectiveness diminishes over time.
