Quiet and economical

The tried and true original

Experience the crisp feeling of cleaner air brought to you by the model that made Blueair a world leader in air purifier design and technology.

The Blueair 403 continues to deliver outstanding performance that has withstood the test of time. Using patented HEPASilent™ technology, it captures 99.97% of the tiniest 0.1 micron particles on level one, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles.

Air is drawn into the unit via an ultra-quiet fan. Airborne particles pass through an ion chamber and are charged to ensure that they adhere effortlessly to Blueair’ s progressive three-stage filter. Cleaned air that is free of impurities is recalculated into the room.

SmokeStop Unit is the ideal choice for allergy sufferers and other health-conscious individuals that need high-efficiency particle removal plus gas and odor control. The SmokeStop filter is a progressive carbon filter with a honeycomb-type structure that improves airflow and has hundreds of odor and gas absorbing carbon pellets. The filter contains 2.0 lbs of coconut shell activated carbonimpregnated with a 70/30 blend of Potassium Hydroxide (KOH) and Potassium Iodide (KI). The carbon eliminates volatile organic compounds (VOC), which are responsible for odors.
