From The Manufacturer

Breathe and sleep easier thanks to Blue Pure 211+ air purifier. With a simple, user-friendly one-button control you can easily select from 3 different fan speeds all of which help to remove allergy causing pollutants and odors. The three-stage filtration process starts with a colorful, washable pre-filter which captures larger particles like dust and pet hair. The air then passes through both a particle and activated carbon filter which catches virtually every airborne contaminant down to a virus in size: pollen, dust, pet dander, mold spores, smoke, allergens and bacteria. Get rid of everyday smells such as food and pet odors naturally without harsh chemicals that mask odors. Filtering air from all sides, millions of ultra-thin fibers of different layers make it less dense than ordinary filters resulting in less clogging, higher airflow and lower noise. In fact, on the lowest setting, the 211+ is described as whisper-silent. This purifier is designed to fit into any room in your house with 2 different pre-filter colors included, blue and dark grey, and many other colors available to purchase separately. With certified results through independent testing from the Association of Home Appliance Manufacturers (AHAM), the Blue Pure 211+ has a clean air delivery rate of 350 cubic feet/minute meaning it will clean the air in a 540 sq. ft. room 5 times an hour.

Expert Reviews


What reviewers liked

Excellent air cleaning performance, quiet operation, large CADR.
Especially effective at removing dust, smoke, and pollen at its highest speed, important for quickly cleaning the air in the room.
This is possibly one of the best quality air purifiers on the market right now. It's especially good at servicing large rooms and has a great modern design. It’s easy to maintain and operate and even though the purifier doesn’t have any smart sensors, it does a wonderful job cleaning the air. The low noise levels and dimmed lights make it a great option for the bedroom too.
It can clear the air in a room up to five times in an hour. It is virtually silent and far more energy efficient than other similar air purifiers.

What reviewers didn't like

The 211+ is also larger, slightly louder, and more expensive to buy and to operate for five years ($700 to $800) than the Coway, and it’s not as easy to move around the home.
Very high operating costs.
Relatively high filter costs and loud on its lowest speed.
One downside of this filtration system is its cost. The annual air purifier maintenance will cost you about $120. This figure is rather high compared to similar purifiers.
No HEPA filter included.
