Blueair 403 Air Purifier

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.

Design

The union of visually pleasing form and effective function is a hallmark of Swedish design, and Blueair is no exception. The Blueair 403 is designed for maximum performance in mid-size rooms. Our Swedish design is not only attractive but built to last. We are known for our durable construction that is made of galvanized steel and is powder coated for durability and environmental protection that produces no chemical off gassing. The air purifier housing is easy to clean, and won't pick up grime and oily stains the way plastic may.

How it works

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.

Filter Fit

Blueair 403 with Particle filter is the ideal choice for allergy sufferers and other health-conscious individuals that need high-efficiency particle removal. The unit contains one polypropylene 3-stage progressive filter that contains millions of ultra-thin fibers with each state trapping progressively smaller harmful particles as they pass through the pleats. The Blueair 3-stage progressive filter effectively removes every type of particulate air pollutants, including allergens, pollen, mold spores, dust, pet dander, bacteria, and viruses.

Blueair 403 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.

The Smoke Stop filter is recommended for use in rooms where heavy gaseous pollutants such as cigarette and cigar smoke or other VOC's are present.
