The X-11 electrostatic air cleaner effectively removes sub-micron particles. Tobacco smoke, nuisance dust and airborne viruses are removed from the airstream after receiving a 10,000 volt electrical charge. Particles are collected on removable and washable filters. This unit is designed to rest inside a 2×4 drop ceiling and sits flush for a clean finished look. The air cleaner delivers 500 – 1250 CFM with a coandra air pattern so air is constantly recirculated back to the unit.
