The NEW Blueair 203 Air Purifier effectively purifies air in rooms as large as 175 sq. ft. It captures 99.97% of the tiniest 0.1 micron particles on Speed One, including allergy-provoking pollen, dust mites, mold spores, and pet dander using patented 2-Stage HEPASilent™ technology and 3-stage progressive filter structure..
