Room and unit air treatment
FreshFilter: Fresher air, room by room.
FreshFilter brings UV-C and photocatalytic air treatment to places a central system can’t reach, such as hotel rooms, modular buildings, classrooms and offices, in units that fit the equipment and spaces you already have.
The problem and our answer
The problem
Odor complaints, stale rooms and musty smells often come from equipment too small for a whole-building fix: fan coils, wall-pack units, rooms with no ducted supply at all.
Our answer
FreshFilter treats the air right where people breathe it. Every model pairs UV-C with PCOR photocatalytic media that targets odors and VOCs, and most add filtration, in a form factor that drops into what’s already there.
Why it matters
What FreshFilter does for you.
Fits what you already have
Fan-coil inserts, wall-pack retrofits, ceiling tiles, in-wall and mobile units, with no major renovation.
Tackles odors at the source
UV-C plus photocatalytic media work on the biological and chemical sources of odor.
Quiet and out of the way
Units live in the ceiling, wall or equipment cabinet, so occupants get better air without another appliance in the room.
See the difference in the data
Pair FreshFilter with Cognituv Connect air-quality sensors and the difference shows up in the data.
