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.
Design
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. 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 air that is free of impurities is recirculated into the room.
