Blueair 121 Vs. 211+ Comparison In Brief
Need to get to the point quickly without having to browse the complete article? I got you a summarized offer here!
Frankly speaking, my preference actually leans toward the blueair 121 over the blue pure 121 versus 211+.
This is due to the fact that it provides more room coverage and also excels surpassingly in performance.
620 square feet filling of space and up to a 400 clean air delivery rate are promisingly the numbers to meet your expectation. As such, it will function incredibly well for extra-large spaces and shall cleanse your surroundings as efficiently as possible.
What about the blueair 211+?
Moderate is exactly what I would say when it comes to this version. An ideal answer for those who do not seek perfection, yet still gain an energy-saving and effective 3-stage filtration, indeed!
To make it clear, if you are on a budget and your space is 550 square feet or less, hesitate no more but go for the blueair 211+!
Differences Between Blueair 121 vs 211+
Design
On the first look, both air purifiers share the same box-like design with an identical width and depth of 13”. However, users would feel like model 121 seems slimmer and more compact due to its height. Blueair 211+ is only 20.3’ tall while the 121-model’s height is 28’. Due to this reason, the 121 air purifier is heavier than its competitive model but still portable.
Granted that, I would not mind having a little more massive-weight friend as long as it is neat and propitious enough to match my health demand. You will not end up carrying it around the space anyway, won’t you?
Blueair 211+ vs 121 all have washable pre-filter, which is available in 5 popular colors. Blueair doesn’t want its product just to be a regular air purifier but a home decor that fits every modern, contemporary house. Unlike other models that use voice recognition or an in-app to control the machine, our air purifiers are regulated by only one friendly-button.
I have to say that I’m more to the Blueair 211+ side. Putting the air purifier less than 10 cm below any object will disrupt the airflow of the unit. Therefore, I prefer to own the shorter version.
Let me give those who have trypophobia a warning. It would be best if you look for other units (Winix 5500-2 vs Honeywell Hpa300, for example of performative yet affordable devices) since the airflow design is covered with holes.
Coverage
The coverage of the two models is a little bit different from each other. Both of the air purifiers can filter very big-size rooms, even up to 700 square feet. With the three-speed control options, the AHAM rate for the 121 model is 620 square feet, while the Blueair 211+ model is only 540 square feet.
As for the CADR ratio, the 211+ machine can clean 350 cubic feet per minute of pollen, smoke, and dust, while the clean air delivery rate of the Blueair 121 model is higher. It takes one minute to wipe away all the harmful particles for a room of 400 square feet.
Understandably, 121 air purifiers are better for a bigger house that requires faster speed. You can choose the one that suits your home most, but for me, I believe the Blueair 121 is the winner.
Filter System
By applying HEPASilent Technology to the works, both models come with two layers of particle filters and a layer of activated carbon that trap smoke and odor-causing elements.
The Blueair 121 vs 211+ machines use Electrostatic Precipitation, making pollutants and particles stickier and easily trapped in the filter. Due to this reason, Blueair machines are quiet and energy-efficient.
Only that the Blueair 121 model also features an upgradeable carbon filter, which the Blueair 211+ have not yet reached.
But aren’t the carbon filters existing in both air purifiers? You may think.
Well they do, but the Blueair 211+’s only serve to absorb milder scents. Meanwhile, the Blueair 121 has a replaceable carbon filter to eliminate odors that are more potent or intense with the activated coconut carbon pellets inside.
Whether you choose one of these two models, it will work perfectly for your house. However, considering the above reason, I have no other way but to announce the triumph as belonging to Blueair 121.
Noise and Energy Consumption
You might wonder how loud will these two devices make and how much energy they consume. Surprisingly, the ratios of both models are the same. They consume between 30-61 watts and 31-56 dB, varying on the speed mode it’s running.
To be honest, this surprises me very much since I believe the Blueair 121 (the bigger-size model) will consume more energy and run louder.
This model can pump more units and cover a large area but can still keep its consumption and noise features to the lowest. Even though they have the same ratios in this round, I’m totally on the Blueair 121 side now!

In my opinion, if your house is big and you have many pets, it’s wiser to choose model 121. It cleans air smoothly, fast, and saves a sufficient amount of energy. However, you can switch to the 211+ device for a more budget option.
