Blue Pure 211 Design and Size

The Blue Pure 211 ushered in a new design direction for the company, and its DNA runs strong within the Blue Pure 121. Thanks to a slightly shorter size, with only 20 inches in height (the Blue Pure 121 is 28 inches), the Blue Pure 211’s footprint is fractionally smaller and it is lighter, but beyond that, changes appear slight.

Cover this Blue Pure 211 from back to front with a still-big fabric pre-filter with different colors (black, blue, yellow, gray, and pink). The price for each color selection is the same as it is for any other member of the Blue family.

This air purifier uses a similar design concept as most of the compact air purifiers at the moment, with a 360-degree air intake to maximize the efficiency of the fan power. The air outlet will be found on top of the Blue Pure 211. With this design, the Blue Pure 211 is much more similar to the Levoit LV-H133.

All air purifiers in the Blue family are really easy to use. You will only need one simple button to control this air purifier, right on the front of the Blue Pure 211.

Blue Pure 211 is an extremely lightweight air purifier. There are only 12.5 lbs for the item, and compared with others in the same price range like the Honeywell HPA300 or Blueair Classic 203 (both with 24 lbs), the Blue Pure 211 is easy to move around your home.

Blue Pure 211 Filters

As the most important criteria to determine an air purifier’s power, we check the performance rating due to the materials of the filters and air filter types used. With the Blue Pure 211+, we will have a simple 3-stage air purification as below.

  1. Pre-filter – The fabric pre-filter of the Blue Pure 211 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 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.

Blue Pure 211 is at a disadvantage without a True HEPA filter, especially as the market for certified HEPA filters becomes increasingly saturated. However, the Blue Pure 211 is still powerful with its unique particle filter with HEPASilent technology, which combines both mechanical and electrostatic filtration in one. This technology enables the Blue Pure 211 to match the performance rating of any HEPA air purifier.

Still, the polypropylene fibers in this air purifier are free of chemicals and naturally anti-bacterial. Also, unlike the cheap air purifier, this particle filter is recyclable as plastic.

Given that this Blue Pure 211 is under the low-range segment, I put it in a great tests with the perfect candidates for the price, the Coway AP-1512HH and Honeywell HPA300. This test is difficult for any air purifiers around $200, as both of these aforementioned air purifiers are the best air purifiers right now. The test conditions are a room of 200 square feet and full run in one hour. It is amazing (but not surprise) that the Blue Pure 211 matched the power of the Honeywell HPA300 with the highest efficiency of 99.95% for any as small as 0.3 microns particles. The Coway AP-1512HH, though with lower ACH/CADR rating, had the same efficiency of 99.95%.

However, the filter cost from this air purifier is a huge jump from the smaller Blue Pure 411, with a total cost of $59. With same performance, the filter cost of the Coway AP-1512HH (or Airmega 200M) is only $45, and will last longer than the durability of 6 months like the Blue Pure 211.

Blue Pure 211 Room Coverage

Blue Pure 211 is really powerful for its size, and can cover up to 540 square feet with no problem. This room coverage is indeed the same with the tower air purifier of Levoit brand – the Levoit LV-H133, which costs less than $100.

The ACH of Blue Pure 211 is a massive 5X rating. 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 clean your room every 12 minutes.

The CADR of Blue Pure 211 is 350 Dust/ 350 Smoke/ 350 Pollen (cfm). This CADR rating is really powerful, as it can surpass even the high fan power like the Honeywell HPA300. This describes clearly how fast this Blue Pure 211 can clean your room.

Blue Pure 211 Sound

Just like the name implied, the HEPASilent technology helps reduce the noise level significantly from all Blueair air purifier. That’s why Blueair can achieve such noise level even with a huge and powerful fan. In the case of the Blue Pure 211, with a more powerful fan than even the Honeywell HPA300, the result of its noise level is truly impressive.

We will have a common noise level from 31 to 56 decibels (dB) within this 3-fan speed air purifier. 31 decibels is only half the noise level of the library, for your information. 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. The Levoit LV-H133 is a lot quieter than the Blue Pure 211, but with a weaker fan performance, too. That’s why with so little noise, I am happy with my Blue Pure 211, especially when this could be the air purifier with the best fan power for the price.

Blue Pure 211 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.

And the Blue family could be the energy-saver of this company, with the Blue Pure 211 only run at 30 watts to 60 watts for energy consumption. For a powerful fan air purifier like the Blue Pure 211, the energy consumption is only half of the Honeywell HPA300. If you want a more energy-saving device, you need to check the Blueair Sense+ immediately. These two are the best air purifiers in low-range at the moment.

An investment in a Blue Pure 211 results in about $11 to $21 annually, which is good for an air purifier with Energy Star rating.

Blue Pure 211 Additional Features

One thing never change in Blue family of Blueair brand, there is no additional features for this one-button air purifier. Blue Pure 211 will come with no additional features, no air sensor or even a timer.

Without these luxury things is not a nightmare for everyone, as an air purifier is mostly for purifying air, right? If you want these features, you need to search for other Blueair air purifiers like the Blueair DustMagnet 5440i. Or else, you could go for the Medify MA-40, Bissell air320 or Airthereal AGH550.
