This Honeywell Air Cleaner is a standalone Electronic Air Cleaner (EAC) that features a two-stage filtration system. The first stage involves pre-filtering, which helps to remove larger particles from the air. The second stage utilizes High Efficiency Particulate Air (HEPA) filtration technology, which is capable of capturing up to 99.97% of airborne particles as small as 0.3 microns. This includes dust, pollen, pet dander, and smoke particles. The unit is designed for ease of use and maintenance with user-friendly controls and easy filter replacement procedures.
