Blueair Blue Pure 311 Review: Best Way for Indoor Air Quality

Suitable Room Size

The Blueair Blue Pure 311 Auto Air Purifier is perfect for rooms that are up to 360 square feet in size. The coverage area of the air purifier’s three-stage filtration system is quite large and can effectively clean a bigger room as well. This makes it an ideal choice if you want to put this air purifier in your living room.

The CADR (Clean Air Delivery Rate) of the Blueair Blue Pure 311 Auto Air Purifier is 300 cubic feet per minute (CFM). The coverage area is 360 square feet, while it can clean the air in a large room up to 540 square feet and filter out 99% of all airborne particles.

But, it is recommended that you place the Blueair Blue Pure 311 Auto Air Purifier in a 360 square feet room only because if the air purifier covers more than its meant-to-be coverage area then it will not be able to filter out all the harmful pollutants and allergens present in that particular room.

The lowest setting of this unit uses 42 watts and the medium setting comes in at 50. This means that you can expect to pay approximately $27-$36 per year to run it on full blast 24 hours a day all year long if your electricity costs $0.12 per kilowatt-hour.
