The Blueair Blue Pure 211 Plus has a no-frills, streamlined design that’s easy to use. It has a 360-degree air intake to pull in airborne irritants from all corners of a room. One button controls the fan speed, indicates when the filter needs replacing, and powers the unit on and off.

Designed for use in large spaces, the Blueair Blue Pure 211 Plus is built with a three-filtration system to pull every possible particle out of the air.

Features and Specs

The Blueair Blue Pure 211 Plus is recommended for larger rooms – effectively filtering the air in areas up to 540 square feet. The unit has a single button control, making it is simple to operate. The control button also changes colors to let you know when it’s time to change the filters.

The unit is relatively lightweight, but it may be challenging to move from place to place or room to room since it doesn’t have a carrying handle or wheels to help it roll. The air purifier uses HEPASilent technology that provides a high airflow and filtration rate while maintaining minimal noise.

Its sleek design allows it to blend in easily with your room décor. The Blue Pure 211 Plus’s three-particle filtration system will filter the air at least four times an hour.

About Blueair

Blueair was founded in the 1990s in Sweden by Bengt Rittri to design the best possible air purifier. Rittri believed that breathing clean air was a fundamental human right, so he brought together a team of filtration experts and top designers who also believed in the importance of clean air, sustainability, quality, and design. 

Blueair has headquarters in Stockholm and Chicago, and its products are available in more than 60 countries. It’s one of the top air purifier brands in the United States and is now part of the Unilever brand of products.

Blueair Blue Pure 211 Plus Air Purifier Review

The Blueair Blue Pure 211 Plus works on a three-particle filtration system. The washable, reusable fabric pre-filter catches large particles and helps extend the life of the unit’s primary filter. The pre-filter can be vacuumed and be washed on a gentle cycle when it needs extra cleaning. Regular, routine cleaning of the filter helps to ensure optimum performance. You can also choose the color of the fabric to help match your room décor.

The combination Particle + Carbon Filter uses activated carbon to pull odors from pets, cooking, or smoke out of the air. It doesn’t use a true HEPA filter, but the primary particle filter still removes up to 99 percent of dust, pet dander, pollen, mold, and other irritants floating around in the air.

Blueair Blue Pure 211 Plus doesn’t have an air quality sensor; however, it automatically adjusts to a higher speed when a higher level of contaminants is detected. It is energy efficient and will not reflect a significant increase – if any -in your electric bill, even if you run it 24 hours a day, seven days a week.

Our Verdict

The Blueair Blue Pure 211 Plus is moderately expensive but worth the investment. Designed for use in large rooms, it is probably best suited for your living room area. It may also be helpful near the kitchen since it also helps pull odors out of the air.

It works well, and even though it doesn’t use a true HEPA filter, it still pulls 99 percent of airborne irritants out of the air and filters at a high rate. Its relatively small size makes it easy to place in any room. But keep in mind – it has a 360-degree air intake, so for it to work correctly, you likely won’t be able to put the unit flush against a wall.

The unit has been independently reviewed and recommended by Consumer Reports – another indication the Blueair Blue Pure 211 is a quality product.


Blueair prioritizes sustainability with products made of high-quality materials and components. All of the Blue Pure 211 parts, including the filter, are recyclable. It is built to last and will hold up well, even if you keep it running 24 hours a day, seven days a week.


The Blueair Blue Pure 211 Plus costs right around 300-hundred dollars and includes free shipping. The company recommends only using Blueair filters, which are costly. They should be replaced every six months and can run as much as 70 dollars apiece. Blueair does have a filter replacement subscription where you can receive a new filter every three, six, or nine months at a discounted price.

Customer Service and Reviews

The product comes with a one-year warranty, but if you register your new air purifier within 60 days of purchase, Blueair will extend the warranty to two years. 

The Blueair website has a reasonably thorough Customer Support page, broken up into categories to help you get answers or help quicker. There’s also a chat feature to provide you with instant feedback. The website has video tutorials on each of its models and downloadable owner’s manuals if you misplace yours. You can contact Blueair with questions by phone or through the website contact form.

Overall, most reviews show customers are pleased with this model. But you will find several customer-specific, negative complaints on the Better Business Bureau’s website. Most of them have to do with incorrect charges for replacement filters or delays in receiving products. But each complaint has a quick response and resolution from the company.

Blueair Blue Pure 211 Plus Customer Reviews:

VERY noticeable difference in air quality

“…within 4 hours there was a VERY noticeable difference in air quality, total 180 by the next day.”

— Blueair Blue Pure 211 Plus Review by D.K. via Amazon




The Blueair Blue Pure 211 Plus is a reliable, easy-to-use air purifier.  Its three-filter system helps purify the air in your home quickly and efficiently. At around 300 dollars, it is more expensive than other brands, but the lasting quality and sustainability features make it worth the price.

The unit is a no-frills air purifier, and it’s a great choice if you’re looking for an option that doesn’t have a lot of bells and whistles. It’s highly effective at pulling out most contaminants in your air and many common home odors.
