Blueair Blue Pure 211i Max HEPA Air Purifier for Extra Large Room over 3000 sq. ft.

A: Thank you for your question! The Blue Pure 211i Max quickly cleans up to 674 ft² in just 12.5 minutes, up to 1,600 ft² in 30 minutes, and up to 3,235 ft² in one hour.

A: Thank you for your interest in Blueair. It's most efficient to run the air purifier with the door closed, as it can cleanse the air more effectively. However, with the door open, it will still clean the air but can take longer since new air is always being reintroduced through the open door.

A: Thank you for your question! We recommend replacing your filter every six to nine months to keep your air purifier performing at its best. RealTrack technology monitors filter usage for you, and the indicator light will turn red to let you know exactly when it's time to replace your filter.
