Residential Cleaning of Indoor Air to Protect COPD Patients

It is a trademarked, patented (U.S. Patent # 7,802,443), U.S. FDA approved Class II medical re-circulating air cleaner, built by Air Innovations, Inc. (North Syracuse, NY) to provide improved indoor air quality in the bedrooms of asthmatic children. Units to be used in the proposed study have a 99.97% efficient filter for particles 0.3 µm in size. The device provides a clean air delivery rate (CADR) of 9 per hour with 1.8 of them being outdoor air.

A placebo mode was added to the HEPAirX to provide only recirculation (without filtration or ventilation using outdoor air) and temperature control of the room air. The placebo filter is made of metal.
