The newly designed SPZ Series air-return sterilization LED edgelit panel features a four layer HEPA filter including antiseptic and antiviral mechanisms. The SPZ offers 24-hour protection against bacteria, virus and other airborne contaminants and pathogens even when the LED light is not illuminated using titanium dioxide photocatalytic oxidation and silver ion nano technolgy. This unit saves space by being a two-in-one package, providing illumination while purifying air in the surrounding area to maintain a bright and sanitized environment in offices, corridors, classrooms, public spaces and any other applications that would require a purified air environment. Filtration system and light can be controlled independently with included remote control (remote can operate up to 25 fixtures).
