Blueair Blue Pure 211+ Review: An Honest & Unbiased Look 

The Blue Pure 211+ is a member of the Blue family of high-performance air purifiers from an established Swedish brand – the Blueair, known for superior performance, low-noise operation, and the stunning Scandinavian design, with simplicity at its core.

Unboxing the Blue Pure 211+: Design & First Impressions

It’s hard not to love the design of the Blue Pure 211+ and the aesthetic appeal of its sleek, rounded square shape. 

It looks a whole lot like the Blue Pure 121 – but smaller.

Granted, at 20 inches tall – and with a width of 13 inches – it isn’t tiny, but it’s not a space-hogging air purifier, either. Plus, it weighs 13 pounds, so it’s surprisingly portable, considering its coverage and performance levels.

The fabric that wraps around the air purifier’s honeycomb-pattern housing serves as a cover and is available in several different colors. It allows you to customize the unit’s appearance to match your home, and more importantly, plays a vital role in its performance: 

The colored fabric serves as a washable pre-filter that traps larger particles before the air moves further into the large, 360-degree intake that sits beneath, drawing air from all sides. 

And to those wondering where all the controls are – there are none. The Blue Air Pure 211+ doesn’t sport any additional features or advanced functions. 

Instead, this air purifier adopts a one-button operation, keeping things as simple and straightforward as possible! 

Putting the Blue Pure 211+ to Work: Performance & Effectiveness

With a full-circle air intake, it’s perfectly capable of sucking in pollutant-laden air from all corners of the room – but this wouldn’t mean much without the equally powerful three-stage filtration system: 

Once the air passes the fabric pre-filter and the large particles are removed, it goes on to the proprietary polypropylene particle filter. Finally, the activated carbon filter takes care of smoke, odors, and VOCs. 

Granted, it doesn’t use a true HEPA filter, but the three filtration stages do eliminate up to 99 percent of common household pollutants, leaving virtually no particles or odors behind. 

It also boasts three fan speed settings – adjustable using the single button on the front of the air purifier – and the ability to perform five air changes per hour in rooms of up to 540 square feet. 

Even more so, the CADR ratings of this Blue Pure 211+ air purifier are pretty impressive, too, amounting to 350 cubic feet per minute for smoke, dust, as well as pollen. 

The noise level depends on the actual fan speed. However, I’m glad to report that, with the range going from 32 to 56 dB, even at the highest setting, it still falls into the “white noise†category. 

Blueair Blue Pure 211+: Pros & Cons to Keep In Mind 


  • Three-stage filtration removes household pollutants and odors
  • Washable fabric pre-filter in multiple colors 
  • 360-degree air intake 
  • One-button operation with a filter replacement indicator 
  • Three different fan speed settings 
  • Stays relatively quiet 


  • Doesn’t use a HEPA filter 
  • Stripped of all advanced features 

Decision Time: Is Blue Air Pure 211+ the Best Air Purifier for You? 

I think that it’s pretty clear from this Blue Air Pure 211+ review that this air purifier covers all the bases, despite its compact frame and lack of bells and whistles: 

It features user-friendly control, three-stage filtration, a 360-degree air intake, a 540-square-foot coverage, and relatively quiet operation, too. 

Plus, changing its appearance is as easy as swapping the fabric pre-filter! 

Don’t settle for a second-rate air purifier; highly efficient and easy-to-use, the Blue Pure 211+ is a clear choice for any household!
