Resideo F300E1001/U Electronic Air Cleaner, 16x20

The Honeywell Home F300E1001 Electronic Air Cleaner is a duct-mounted whole-home filtration system that captures up to 98% of airborne particles between 3.0 and 10.0 microns, including dust, pollen, pet dander, and mold spores. Designed for forced air heating, cooling, or ventilating systems with a 16-inch by 20-inch return duct opening, this electronic air cleaner uses an electrostatic charging process to trap particles that standard filters miss. It handles air flow up to 1200 CFM and operates on standard 120-volt household power. The F300E1001 replaces older models F300A1620 and FH8000A1620, delivering cleaner air throughout your home without the recurring cost of disposable high-efficiency filters.

• Electrostatic Filtration Technology: Uses ionizing wires and charged collector cells to attract and trap particles as small as 3.0 microns. This captures fine dust, allergens, and smoke that pass through standard furnace filters, reducing household dust and improving indoor air quality.
• 98% Particle Capture Efficiency: Removes 95% of large particles (3.0 to 10.0 microns), 88% of medium particles (1.0 to 3.0 microns), and 73% of small particles (0.3 to 1.0 microns) according to ASHRAE Standard 52.2-1999. This level of filtration helps relieve allergy symptoms and protects HVAC components from dust buildup.
• 1200 CFM Maximum Airflow Capacity: Handles homes with air handlers moving up to 1200 cubic feet per minute without restricting airflow. The unit maintains only 0.26 inches of water column static pressure drop at maximum flow, so your furnace or air conditioner runs efficiently.
• Self-Regulating Solid State Power Supply: Automatically adjusts voltage to maintain peak filtration efficiency even as the collector cells load with dirt. This means consistent performance between cleanings without manual adjustments.
• Washable Collector Cells: The electrostatic cells clean easily in a dishwasher or tub of soapy water and reinstall for years of reuse. You avoid the ongoing expense of buying replacement cartridge filters every few months.
• Included Media Post-Filters: Two disposable post-filters (part number 50000293-001) enhance filtration by catching larger particles before air reenters your living space. These inexpensive filters extend the time between cleanings of the main electrostatic cells.
• 10-Year Clean Coil Guarantee: Honeywell guarantees the evaporator coil downstream of the F300E1001 will stay clean for 10 years when the air cleaner is properly maintained. This protects your HVAC investment and ensures efficient system operation.
• Low-Profile Access Door with Test Button: The front door includes a built-in test button to verify system operation at a glance. A compact door design with stamped metal construction provides strength and corrosion protection in a package that fits standard duct spaces.

The F300E1001 mounts in the return air duct of forced air HVAC systems, including furnaces, air conditioners, heat pumps, and ventilation systems. It requires a 16-inch by 20-inch duct opening and approximately 6.75 inches of depth for installation. The unit operates on 120 volts AC at 0.4 amps maximum (60 Hz) and must be wired to a power source that activates when the HVAC blower runs. Replacement media post-filters use part number 50000293-001, and replacement prefilters use part number 209989 (sold separately in packs of two).

Install the F300E1001 in the return air duct between the air intake and the furnace or air handler, following the directional airflow arrows stamped on the unit cabinet. The cabinet includes stamped mounting tabs with accessible screw holes on both flanges for secure duct attachment. For maintenance, wipe the ionizing wires with a damp cloth monthly for a quick efficiency boost. Full cleaning of the electrostatic cells in hot soapy water or a dishwasher restores peak performance and is recommended annually or more frequently in high-dust environments. Replace the media post-filters as they become visibly loaded with debris, typically once per year.

The Honeywell Home F300E1001 is backed by a 10-year Clean Coil Guarantee that protects the downstream evaporator coil when the air cleaner is maintained according to manufacturer guidelines. The unit is UL Listed under report E30954 for safety and performance.

A: The electrostatic collector cells in the F300E1001 are designed to last for many years with proper cleaning. Honeywell recommends washing the cells annually to restore peak efficiency, though units in dustier environments may benefit from more frequent cleaning every six months. The disposable media post-filters (part number 50000293-001) should be replaced as they become visibly loaded, typically once per year depending on usage.

A: The F300E1001 operates only when the HVAC blower is running. When the blower in your furnace, air conditioner, or heat pump turns off, the electronic air cleaner also turns off automatically. This ensures filtration occurs whenever air circulates through your duct system without wasting electricity when the system is idle.
