Other Blueair’s Air Purifier Reviews

Blue Pure 211 Auto Price

If you like your air purifier strong, affordable and retro, the new edition of the Blue Pure 211 Auto may be the best air purifier for you. It keeps the core of the Blue family: simplicity and sleek design, something that’s firmly rooted since the original Blue Pure 411.

The Blue Pure 211 Auto will be the smarter version of its predecessor, while the flagship Blue Pure 121 is still waiting for its smart version. That’s why it is currently the best option for large rooms you can buy from Blueair’s Blue family.

The Blue Pure 211 Auto also has gotten a price hike over its predecessor to $339, but even at this price point, it is still a formidable candidate of the best air purifier. It has superior performance and its CADR rating per watt is second to none.

However, you will only have the convenience of the Smart Sensor, and forget about everything else. Seriously the idea of “plug and play simplicity” is great, but nice touch of latest technology will boost the ranking of this air purifier better. Still, against the best competitors like the Hunter HP800, LivePure Bali or Vornado PCO375DC, the performance of this Blue Pure 211 Auto is one thing you desire.

But other competitors don’t stay still, and the release of the Winix XLC and Levoit Core 600S can shake the position of the Blue Pure 211 Auto tremendously.

Blue Pure 211 Auto Design and Size

There is familiar but there is expected update to the design. Blue Pure 211 Auto is such a well-worn look that we instinctually took to it, even though we know it’s not a look that’s ‘in’ right now.

It is the form of the Blue Pure 211, covered with the new customizable pre-filter colors that’s Scandinavian inspired. By default you get the Arctic Trail version, and you can ask Blueair for your most favorite option.

The Blue Pure 211 Auto stays on its rectangular shape and it’s quite big at 20 inches in height and 13 inches in width and depth. We still run the same bottom-to-top airflow system concept, and this design requires really big fan power.

We have only one button to control, which is physical and it feels great. It differs from the old model as the one-touch button is located on top, making it easier to touch and play. Not to mention the top air outlet is a bit better stylish (at least in my opinion).

Blue Pure 211 Auto is the same lightweight air purifier as the predecessor. It is only 12.5 lbs and you can move it around your home easily.

Blue Pure 211 Auto Filters

As the most important criteria to decide one air purifier’s power, we check the performance rating due to the materials of the filters and air filter types are used. Blue Pure 211 Auto remains the same 3-stage air cleaning system from its predecessors.

  1. Pre-filter – The fabric pre-filter of the Blue Pure 211 Auto is outside the air purifier and can catch the large particles. This pre-filter is washable or vacuumable.
  2. Particle filter – Instead of using a True HEPA filter, the Blue Pure 211 Auto uses a polypropylene fiber filter to help capture 99.97% of all allergens as small as 0.3 microns like dust, dust mites, pet dander, pollen and fungi (HEPA technology).
  3. Activated Carbon Filter – The Activated Carbon filter is added inside the Particle filter and effective against smoke, odors, gases and VOCs.

Combining both electrostatic charging of particles and mechanical filtration using a unique filter design, the Blue Pure 211 Auto’s HEPASilent technology is able to maximize its fan power, while keeping the highest performance like a real True HEPA filter.

Still, polypropylene fibers from this air purifier are free of chemicals and naturally anti-bacterial. Also, not like the cheap air purifier, this Particle filter is recyclable as plastic.

The Blue Pure 211 Auto is certified by both the AHAM and CARB for being efficient and safe to use. In Breathe Quality, the Blue Pure 211 Auto is tested against the top dogs of $300, most notable the Levoit Core 600S, LivePure Bali, TruSens Z-3000 and Oransi Max. Together with the Levoit air purifier, the Blue Pure 211 Auto is the clear winner at cleaning 99.93% of all particles down to 0.3 microns in the room of 300 square feet, for 1 hour.

However, the filter cost from this air purifier is a huge jump from the smaller Blue Pure 311 Auto, with a total cost of $69. You need to change the filter every 6 months, and that’s why the Blue Pure 211 Auto’s annual cost ranking is lower than its smaller brothers.

Blue Pure 211 Auto Room Coverage

Blue Pure 211 Auto can be the most powerful air purifier in terms of fan power, tested by the Association of Home Appliance Manufacturers (AHAM). It is recommended for any room up to 540 square feet.

The ACH of Blue Pure 211 Auto is 5X. As a well-known brand for making high quality German-engineered fan, it’s not surprise that all of Blueair’s products will have high air changes per hour rating, which results in the Blue Pure 211 Auto clean your room every 12 minutes.

The CADR of Blue Pure 211 Auto is 350 Dust/ 350 Smoke/ 350 Pollen (cfm). This CADR rating is top-tier, and it is proved to be better than any competitor.

Blue Pure 211 Auto Sound

As its name implies, HEPASilent technology dramatically reduces the noise level of all Blueair air purifiers. Even with a huge and powerful fan, Blueair is able to achieve such a noise level. With a fan that is more powerful than even the Honeywell HPA300, the Blue Pure 211 Auto’s noise level is simply remarkable.

Blue Pure 211 Auto has a common noise level from 23 to 56 decibels (dB). 23 decibels is even better than its predecessors, and you virtually can’t hear the noise. Even at the highest setting, the noise level of 56 decibels is still acceptable, as it is measured as the normal conservation at home, which is easily to be ignored.

Blue Pure 211 Auto Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” An air purifier is designed to run for a long time to be efficient. Therefore power consumption is always one important criteria when you decide to buy one air purifier.

With the Blue family marketed to be the energy-saver of this company, the Blue Pure 211 Auto only run at 4 watts at lowest, and 38 watts at highest fan power. For a powerful fan air purifier like Blue Pure 211, the energy consumption is only one third of the Honeywell HPA300.

An investment in a Blue Pure 211 Auto results in about $1.4 to $14 annually, which is impressive for an Energy Star air purifier.

Blue Pure 211 Auto Additional Features

Like the Blue Pure 411 Auto and Blue Pure 311 Auto, the Blue Pure 211 Auto has Smart Sensor. It isn’t superior in this price range anymore, but it is pleasant to have such feature in a simple air purifier. The LED sensor matches with the fabric pre-filter beautifully. Noted that the Blue Pure 211 Auto has both dust and gas sensors.

Other than that, the Blue Pure 211 Auto still lives up to the core of the Blue family – simplicity. It has only one touch to control the whole air purifier.

Otherwise, you only benefit from a 1-year warranty. Moreover, do not attempt to bring the air purifier outside of the United States or Canada, or your warranty will be void immediately. All Blueair warranties are non-transferable.

Blueair air purifiers from the Blue family have only a 2-year warranty from the date of purchase (with valid proof of purchase). One quick reminder: Blueair doesn’t cover warranties from third-party sellers, so buying from Breathe Quality’s deals is highly recommended.

Our verdict

Blue Pure 211 Auto, just like its brothers, brings a lot of power and headroom for a compact air purifier, while saving power and remaining quiet. It ranks S in pure performance, but still it lacks some basic features even for a $300 air purifier, and its annual cost jumps higher than the previous models like the Blue Pure 311 Auto. It is still a great recommendation in this price range from us, but the Levoit Core 600S is still our number one pick.
