The F118 In-Ceiling Media Air Cleaner uses a three-speed direct-drive, forward-curve blower motor and a 95 percent DOP particle filter to capture airborne particles such as dust, soot, and cooking smoke from the air circulated through it. When equipped with two CPZ modules, the air cleaner also adsorbs gases and odors from the air passing through it. The F118 is recommended for use in rooms with drop ceilings, and for spaces with structural ceilings not higher than 16 feet (4.8 meters) where there is a minimum one-foot (0.3 meter) clearance between the drop ceiling and the structural ceiling.
