The Honeywell f100f1620/u is a duct-mounted media air cleaner designed for residential and light commercial forced air systems. It captures airborne particles as small as 0.3 microns using a high-efficiency MERV 11 media filter. HVAC technicians and installers rely on this unit to improve indoor air quality without the complexity of electronic air cleaners. The cabinet measures 16 inches by 20 inches and accommodates a 4-inch media filter. It mounts directly in the return air duct and works with all gas, oil, and electric forced air furnaces. It is also compatible with compressor-based cooling systems up to 5 tons. The unit requires no electrical connections, making installation straightforward and code-friendly. The zinc-coated, roll-formed steel cabinet resists corrosion and is strong enough to support the weight of a residential furnace and evaporator coil. No special tools or wiring are needed. The unit ships complete with the cabinet, access door, and a MERV 11 filter ready for immediate installation. Maintenance is limited to periodic media filter replacement. Compatible replacement filters include FC100A1003, FC200E1003, and POPUP1620. For installations where air quality requirements may increase over time, the cabinet is designed to accept higher-performing media filters or an upgrade to an electronic air cleaner. Airflow capacity reaches a maximum of 1200 CFM, making it well-suited for most residential ducted systems. Fractional efficiency ratings follow ASHRAE Standard 52.2-1999, with E1 at 32 percent for particles 0.3 to 1.0 microns, E2 at 72 percent for particles 1.0 to 3.0 microns, and E3 at 96 percent for particles 3.0 to 10.0 microns. The filter element carries a UL Listed rating under UL900 Class 2. This is a practical, reliable solution for contractors specifying baseline air filtration in new or retrofit HVAC installations.
The Honeywell f100f1620/u delivers reliable MERV 11 air filtration for forced air systems up to 1200 CFM with a durable, low-maintenance design that supports future upgrades. It is a dependable baseline air quality solution for residential HVAC applications.
