In independent tests of the top 21 air cleaners, this was rated the best for combined particulate removal, the best general filter, the best for gas and odor removal, and as the best overall air cleaner. Encased in solid welded steel with a durable baked-powder coating to eliminate the threat of out gassing. The ultra-quiet motor only uses 90 watts on the high setting (50% less than in comparable models) and can run 24 hours a day without overheating. Three speeds and a 360-degree intake will exchange the air in a 150 sq. ft. room up to 10 times an hour. A top-grade carbon filter removes odors and gasses and a natural mineral zeolite filter captures small molecules like formaldehyde and ammonia. In addition, 80 sq. ft. of laser-tested HEPA media captures 99.97% of all particles larger than a 0.3 microns - all these sealed for optimal efficiency and packed in a filter cartridge that needs to be changed only every 5 years. Castor wheels. USA.
