Quiet and economical

Blueair 503
The strong, silent type
The Blueair 503 (555EB) 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
SurroundAirâ„¢ 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.
