The Honeywell® F11U Air Cleaning and Treatment System uses a
high efficiency media filter to trap airborne particles, while built-in
ultraviolet (UV) lamps inactivate a wide range of contaminants. The
filter traps up to 95% of dust, soot, mold, spores, pollen, and other
particulates. The UV kills more than 80% of serratia marcescens bacteria
in the 900 cubic feet of air that flows through the system every
minute. Combined, the two technologies can achieve a 99% capture/
inactivation rate effectiveness.
