The 211+ is easy to use. You only get one single button that controls all settings. You tap the button once to power it on and tap it repeatedly to control the fan speed between low, medium, and high.

The Blueair Pure 211+ is an excellent air purifier with a simple setup process.

The BlueAir Pure 211+ is built for performance and simplicity. With fewer features than other air purifiers, this device does one thing exceptionally well: clean the air! And with its sleek design, you won’t mind spending time in a purer atmosphere without sacrificing aesthetics or functionality.

Before activating the Blueair 211+ air purifier, there are only a few easy steps that need to be taken. The particle-carbon filter is already equipped in the unit and ready for use; all we have to do is get prepared with the pre-filter. That’s it – nothing else!

When you purchase the Blueair 211+, two stylish fabric pre-filters – Diva Blue and Dark Shade – come included! Simply choose your preferred filter, slide it onto the bottom half of the device, separate the air purifier’s motor from its filters by pressing down on either side, then place the pre-filter over the metal housing along with the bottom part of the machine. It’s that easy to get quickly set up for improved air quality in no time.

With its sleek design and top-notch performance, the Blueair 211+ is a great addition to any room. This air purifier does more than just bring clean air into your home – it can also add an aesthetic touch with minimalism that looks good in any space. A thorough review of this model reveals why it belongs among the best options for improving indoor quality!

Blue Pure 211+ Features

The Blueair Blue Pure 211+ is a breath of fresh air in the world of air purifiers. Rarely will you find such minimal simplicity when it comes to this piece of technology – no advanced features, clever extras, or stylish elements here! Though some may be disappointed at the lack of options like a timer that can come in handy for everyday use.

If you’re seeking a device with air quality sensors, the Blueair Blue pure 211+ Auto is an ideal choice. This advanced model offers a smart sensor option and boasts more features than its predecessor, the Blueair 211+. Though this alternative lacks sensors as it’s not tech-savvy, it remains compatible with any associated smart plug for added convenience.

Flexible Pre-filters

This model has exciting features. One is the replacement pre-filters in 5 different colors. People who are dynamic will like this because they can change the color of the device to something brighter.


The Blueair 211+ provides an optimal level of convenience and simplicity, which is the basis on which it was designed. It is effortless to install, with a single button that controls all options available – you can never press the wrong one!

Filter Reset Indicator

The Blueair 211+ offers a convenient filter reset indicator, eliminating the need to keep a record of when it’s time for you to replace your air filters. Now, this helpful feature will do all the work and inform you precisely when that is!

When the indicator surrounding the control knob glows yellow, it’s a sign that you should start planning to replace your filter soon. In addition to white, this indicator has two other colors. (this is after about 5 months of use).

If left unaltered, the indicator will begin to flash red. This is a warning that your filter needs to be replaced quickly – usually after 6 months of usage. Don’t ignore this signal as it’s imperative you replace the filter as soon as possible!

Certified Device

Blueair is an esteemed company that takes no chances when it comes to its products, which is why the Blueair 211+ has been accredited as a reliable air purifier.

Blueair’s 211+ model has earned a trifecta of certifications: AHAM, Energy Star, and CARB. Each confirms quality assurance that this air purifier is capable of removing up to 350 CADR particles with recognized energy efficiency – plus keeps it ozone free so Californians can breathe easy knowing they’re buying safe!

Blue Pure 211+ Filters

The Blueair 211+ is armed with a three-tier filtration system, including a Pre-filter, a particle filter, and an activated carbon filter.

Additionally, it’s equipped with the innovative HEPASilent technology that can never be switched off – this ionizing process charges particles in the air so they stick together for easier capture.

To extend the life of the particle filter, a fabric pre-filter is utilized as its first line of defense. This reusable cloth traps large particles such as dust and pet hair to keep them out of the system before they reach it.

Not only is the pre-filter cover a practical solution, but it’s also an aesthetic choice! With our device we tested out the black and blue option, however, you can also get creative with two other colors: white or pink. Installing this fabric cover adds color to your space while providing a reliable function for your device.

Particle Filter (Not-HEPA)

Despite not having a True HEPA filter, the Blueair 211+ still performed remarkably well. This demonstrates that even without patented technologies in filtration, quality air purification is possible thanks to reliable Blueair technology!

In order to eliminate airborne particles like pet dander, pollen, and dust, the particle filter is utilized as a secondary filtration stage. This procedure serves as the primary level of filtration for your home or office environment in order to improve air quality.

Carbon Filter

The last step in the filtration process is a carbon-coated fiber filter, designed to take out any household smells from sources such as pets, cooking, and smoking.

After running tests, the Blueair has proven successful in removing smoke and foul odors from a given space. However, when confronted with large volumes of daily smoke exposure, it accumulates dirt more rapidly and may need to be replaced sooner than expected.

To put it succinctly, the Blueair 211+ cannot handle higher smoke levels due to its limited carbon content. Devices including the Winix 5500-2 and Alen FLEX make use of larger carbon pellets which are far more effective at absorbing smoke odors than the Blueair 211+. Therefore, these machines offer better odor control for high-smoking areas.

Blue Pure 211+ review: Performance

We put the BlueAir Pure 211+ to the test in a medium-sized office room, taking initial air quality measurements before and after running it for an hour on its highest setting. The results of our experiment gave us valuable insight into how well this air purifier performs!

In an astonishing hour, the BlueAir Pure 211+ managed to filter out a remarkable 98.8% of all airborne particles in our medium-sized testing room (approx 14’x10′).

The Blueair 211+ air purifier is specially built for areas as large as 540 sq. ft., yet its performance in bigger spaces has made it clear that you can use this model outside of the recommended dimensions! Not only did we find it successful, but also consistently efficient in a room slightly larger than what was proposed!

Even though this model is not a True HEPA air purifier, I find the Blueair particle filter to be incredibly efficient and effective in its job; otherwise, it wouldn’t be as Highly praised as it is.

The Pure 211+ performed remarkably well in our tests, as it reduced the PM2.5 levels to an optimal 0.1 – precisely what we seek from a top-notch air purifier! Although I wished for the PM10 level to be brought down to 0.1 too, achieving a score of 0.2 is still remarkable and must be commended.

Blue Pure 211+ Size and Dimensions

This air purifier packs a hefty 15-pound (7 kg) punch and is quite bulky, measuring in at 20.5 x 13 x 13 inches (52.2 x 33 x 33 cm). Be sure to factor in the size of this device when making your purchase; it will take up plenty of space!

The BlueAir Pure 211+ is a compact package of clean air, measuring 13″ long and wide with a 20″ boost in height. All that power comes at the price of only 12.5 lbs.

Blue Pure 211+ Operation Cost

Examining the size, airflow, and capacity of this device leads us to think that its motor must be extremely powerful.

But surprisingly enough, Blueair 211+ only runs on a 61W motor – which definitely doesn’t meet our expectations in comparison with other air purifiers using 10W motors but being much smaller!

If you opt for the Blueair 211+ and run it on maximum speed daily, your electricity bill would only be slightly affected; an additional $4.3 per month to be exact!

Blue Pure 211+ Coverage

During testing, it proved its effectiveness by reducing the PM2.5 down to 0.1 and achieving an AQI of 1. Not only that, it provides coverage of 540 sq. ft., making sure that your space is well-purified regardless of the size.

The Blueair air purifier is AHAM verified and boasts an outstanding CADR of 350CFM (590 m3/hr). This means that in a space as large as 540 sq. ft. (50m2), it can circulate the air 4.8 times every hour – one of the highest levels on the market!

It’s no surprise then, that this device has been particularly designed for larger rooms such as offices or open-plan living areas; making sure clean breathing is available to everyone with its 211+ model.

Blue Pure 211+ Noise

With just three fan speeds, the Blueair 211+ is a beast of a device that produces an amazing amount of airflow. Despite its size and potential for high noise levels, I was pleasantly surprised to find out how quiet it really is. It’s truly impressive how much volume this machine can generate with such power — kudos to the engineers who designed it!

Delivering sound at just 23.8 dBA at its lowest speed, the Blueair 211+ produces peaceful and tranquil noise levels while still functioning powerfully; when running at maximum speed, it generates a soft 45.7 dBA and with medium speed, it can generate only 32.9 dBA.

Common noise levels:

  • 20 dB – rustling leaves
  • 30 dB – whisper
  • 40 dB – quiet library, babbling brook
  • 50 dB – refrigerator, moderate rainfall
  • 60 dB – normal conversation, dishwashers
  • 70 dB – traffic, showers
  • 80 dB – alarm clock, telephone dial tone

Pros And Cons

  • The coverage area of 540 sq. ft. 
  • Energy efficient
  • Washable pre-filter
  • Great build quality
  • 360-degree air intake

The Blueair 211+ air purifier is a one-of-a-kind device that will help you breathe easier. Equipped with Swedish filter technology, this powerful tool captures 99% of airborne pollutants such as dust, viruses, and bacteria – making it an ideal choice for allergy sufferers or anyone looking to improve the quality of their home’s atmosphere.

It provides outstanding airflow capacity at two speeds along with supplemental coverage up to 540 sq ft; plus its pre-filter can be washed for long-term maintenance!

With all these amazing features in tandem, the incredible performance achieved by this compact yet efficient model surely left me nothing short of amazed.

With all of this evidence, it is clear that the Blueair 211+ air purifier is undoubtedly a great choice for any consumer. If you are considering buying an air purifier, then investing in the Blueair 211+ model would be a wise decision!

Still, remember that this device requires a bit more maintenance each year. But I don’t think that should be an issue given the incredible advantages you get from Blueair 211+.
