The Blueair 203 is the most compact unit in the Blueair line. It is an excellent system for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air.
The 203 effectively purifies air in rooms as large as 200 square feet. Using patented two-stage HEPASilent" technology, it captures 99.97% of the tiniest .1 micron particles on level one, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles. This same filter technology earned the larger Blueair 503 Best of Class ranking in independent testing of Clean Air Delivery Rates. The 203 provides comparable performance for smaller rooms.
Value-added features include quiet operation, low energy use, steel construction and easy maintenance: simply open the side, slide out used filters and drop in replacements every 6 months.
