Musty air in a stairwell isn't a cleaning problem. It's moisture your AC never removed.
Most systems dry the air only as a side effect of cooling, so when they cycle off at night and on weekends, the damp stays and things start growing where nobody looks.
BF-DOAS™ removes moisture on purpose with TE-Sal™ technology and brings in fresh, filtered outside air at the same time. The building stays dry and lightly pressurized, so nothing musty creeps back in.
Drier spaces. Cleaner air. Fewer sick days.
