Drop-in 2×2 ceiling-tile UV-C + PCOR purification — passive supply-air or active fan-powered.
The FreshFilter Ceiling-Tile Purifier brings UV-C disinfection and PCOR photocatalytic air cleaning into a standard 2×2 ceiling grid — a discreet, zero-footprint way to continuously clean the air in occupied commercial spaces. It comes in two configurations for different rooms. The FreshFilter-Tile replaces a ceiling supply diffuser and polishes the HVAC supply air as it enters the room, with optional surface-treatment lamps. The Overwatch 2×2 is a self-contained, fan-powered unit that actively pulls, filters and disinfects room air on its own — no ductwork or fresh-air intake required — covering up to 1,100 sq ft at a quiet 47 dB. Both combine dual germicidal 253.7 nm UV-C lamps with layered PCOR filtration to inactivate pathogens and break down VOCs and odors, and both are Cognituv Connect–enabled for wireless monitoring and verification. A fit for offices, healthcare, schools and hospitality.
