Blueair 603 Smokestop™ Air Purifier


The Blueair 603 Smokestop™ Air Purifier cleans indoor air of odors, fumes and allergens in larger rooms up to 640 sq ft (about 25’ x 25’). The Smokestop version of the Blueair 603 Air Purifier combines all of Blueair's filtration technology onto a HEPA Smokestop filter (3 HEPA Smokestop filters included per machine). This filter combines Smokestop's active carbon filtration to absorb fumes, heavy odors and VOCs (including tobacco smoke), with Blueair's HEPASilent™ particle filtration to remove 99.97% of airborne allergens to 0.1 micron.

The Blueair 603 Smokestop features an airflow rate of 90-455 cfm with 5 air exchanges per hour. Cleaned air is gently diffused back into the room with no drafts thanks to Blueair's SurroundAir™ technology. CADR ratings for particle filtration (an industry measure of contaminant-free air delivered by an air purifier) are >400 for dust, 415 for pollen, and 415 for smoke. 5-Year Manufacturer's Warranty.
