The F116A1021 is a Honeywell two-stage ducted or stand alone HEPA air cleaner. It cleans by removing particulates, odors, and volatile organic compounds (VOCs) from the air passing through the two stages of filtering.
The first stage is a prefilter rated 30-40% ASHRAE dust spot efficiency. This prefilter captures large particles, and is disposable. The second stage is a 99.97% HEPA-grade filter. This filter is certified to be 99.97% D.O.P. efficient at capturing 0.3 micron air- borne particles that pass through the filter such as pollen, cat dander, dust, tobacco smoke, and mold spores. All filters are included. It delivers powerful air cleaning for commercial and light industrial environments.
These air cleaners operate separate from the HVAC system. Using separate ductwork helps isolate airborne particles and odors so they can be captured, and may even be used to create an "air curtain", an invisible barrier of positive or negative air pressure that controls the flow of indoor air pollutants. The expense of additional ductwork is offset by the reduced amount of outdoor air that needs to be imported, and the cost of conditioning that outdoor air may require.
Maintenance takes just minutes with no tools required. All units allow easy access to the replaceable media. All feature a one-horsepower, forward-curve, direct drive blower motor that moves up to 2000 CFM of air passing through the filters. These units are simple to install, operate, and maintain and are backed by a two-year limited warranty.
