The Honeywell Store has assembled a selection of Honeywell Electronic Air Cleaners that features a certification of 94% efficiency in the removal of 0.5 micron air particles that pass through its filters. This would include airborne particles such as pollen, dust, tobacco, smoke, mold spores and cat dander. All Honeywell Electronic Air Cleaners featured at the Honeywell Store utilize a Coanda Airflow system with a three speed motor driven fan. Maintenance takes just minutes with no tools required. The grill swings down effortlessly for prefilter and electronic cell cleaning or replacement and is removable for easy cleaning. Honeywell Commercial Air Cleaners are simple to install, operate and maintain.
