The union of visually pleasing form and effective function is a hallmark of Swedish design, and Blueair is no exception. The Blueair 503 is designed for maximum performance in large 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. 

Sleek Swedish styling and HEPASilent™ filtration technology makes Blueair a very popular choice. Combining ionizer, electrostatic, carbon and HEPA-grade filter technologies without producing any external ozone; the Blueair delivers large amounts of clean air quietly. Blueairs 3-stage filter technology achieves better results with CADR ratings that are among the highest in the industry. Blueair’s SurroundAir™ system achieves peak performance by drawing in dirty air from the sides and bottom and releasing clean, filtered air from the sides and top. Cleaned and purified air that is free of impurities is recirculated into the room.

Changing Filters is easy and quick:
Easy access filter. No bending to change the filter. Easily replace filters by removing the top of the unit and sliding out the old filters.

Blueair 503 with HEPASilent Particle filters 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 progessively 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 503 SmokeStop Air Purifier 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 carbon impregnated 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 SmokeStop filter is recommended for use in rooms where heavy gaseous pollutants such as cigarette and cigar smoke or other VOC's are present.

Quiet on lowest setting. Noisy on highest setting but low setting works perfectly fine for removing allergens. Also works exceptionally well for removing bad odors like a dead squirrel in your attic which is what I had. Kept it on medium all day for the first day and by the end of the day the bad odor was completely gone. Now keep it on low setting, barely hear it and it works very well. I highly recommend it.
