The Honeywell F300 Whole-House Electronic Air Cleaner is the most advanced and easy-to use solution for improving your indoor air quality. When installed into your home's heating and cooling system, an Electronic Air Cleaner traps and filters up to 99%* of airborne particles passing through the system to make sure cleaner air is distributed to all rooms in your home. It works by placing a charge on airborne particles and then collecting them like a magnet. Plus, Electronic Air Cleaners are low maintenance - simply wash the cells in your dishwasher or sink when needed. F300 optimizes efficiency with airflow capturing up to 98% of particles that pass through it. It operates with all gas, oil and electric forced warm air furnaces and AC systems, and is available in four sizes to fit most ducts.
