Blueair 503

The strong, silent type

The Blueair 503 is an excellent choice for people living with allergies, asthma, or other respiratory conditions, or for anyone who wants cleaner, more breathable air. Designed for large rooms up 580 ft2, the Blueair 503 effectively purifies indoor air. This powerful air purifier offers quiet operation by gently diffusing air through an area six times greater than the average air cleaner, thanks to its SurroundAir™ system. This provides an exceptional air exchange rate and better indoor air quality. Plus you can easily move the Blueair 503 around your living space thanks to convenient caster wheels.


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.

How it works

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. Blueair's 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 air that is free of impurities is recirculated into the room.

Filter Fit

The Blueair 503 with Particle filters is the ideal choice for allergy sufferers and other health-conscious individuals that need high-efficiency particle removal. The unit contains three filters with a unique gradient and progressive structure made of polypropylene, a plastic material that is naturally anti-bacterial, fiber shredding resistant and when combusted the filters convert to harmless water and carbon dioxide. These filters effectively remove every type of particulate air pollutants, including allergens, pollen, mold spores, dust, pet dander, bacteria, and viruses.

The Blueair 503 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 unit contains 3 Smokestop™ progressive carbon filters each with a honeycomb-type structure that improves airflow and has hundreds of odor and gas absorbing carbon pellets. Each 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.
