Surround yourself with clean air

Among the most elite air purification systems available, the Blueair Classic 503 is designed for rooms up to 580 square feet in size. Its progressive Blueair SurroundAir™ system offers whisper-silent operation using air filters that have six times greater surface area than the average air purifier. Surround yourself with clean air. Stop worrying about asthma and allergies, and start enjoying the benefits of breathing indoor air that is virtually free of pollutants.

Unique Blueair HEPASilent Technology

Blueair HEPASilent Technology captures 99.97% of all airborne pollutants down to 0.1 micron in size. Our HEPASilent Technology unites the best in mechanical and electrostatic filtration. This revolutionary combination ensures that your Blueair purifier delivers results far superior than either mechanical or electrostatic technology alone.

No drafts at any speed

The Blueir Classic 500 series features Blueair SurroundAir with large air intake and outlet areas. This diffuses the airflow and reduces drafts yet maintains an extremely high air flow.

Countdown to change

To ensure you’re never getting less than high quality clean air, the Blueair Classic 503 come with a timer to alert you when your filter needs to be changed. The magnetic backing allows you to attach the timer to your unit, refrigerator, or any other magnetic surface. And when it's time to change, the filters are easily replaced by removing the top of the unit, sliding out the old ones, and sliding in the new.
