A beautifully designed powerhouse that quietly and effectively cleans the air in large, open-plan spaces with dead-simple operation.
Blueair Blue Pure 211+ Auto Review: Power and Simplicity for Large Rooms
For those with large living rooms or open-concept homes, the Blueair Blue Pure 211+ Auto is a game-changer. Over our 45-day test, its high Clean Air Delivery Rate (CADR) made a tangible difference in a 550 sq. ft. space, significantly reducing dust and lingering odors. The new 'Auto' mode, powered by an integrated particle sensor, works flawlessly, ramping up the fan when needed and keeping quiet otherwise. Its combination of proprietary HEPASilent technology, which provides high performance with low noise, and its stylish, customizable design makes it a premium, highly effective solution.

Real-World Usage
Practical considerations for daily operation
Daily Routine Impact
It's a silent guardian for your home's main living area. You set it to auto and forget it exists, apart from noticing less dust and fresher air.
Learning Curve
Use right out of the box
Maintenance
The fabric pre-filter can be vacuumed or machine-washed. The main particle + carbon filter needs to be replaced every 6-9 months.
Portability
Not portable. It is a large, stationary appliance intended for a single, large space.
Manual Use
Perfect. It is designed to be a simple, tactile experience. One button cycles through fan speeds and activates auto mode. It's foolproof.
