The details

Whether you want to get rid of unpleasant odors of pet litter, smoking, wildfires, and cooking, or the tiny airborne pollutants that just don’t seem to go away, the sleek and robust Blueair Blue Pure 211+ Air Purifier is ideal for you. It features washable pre-filters, 360 degrees airflow, and many other features to help you improve the air quality indoors.

Noise level

We liked how silently the unit operated throughout the day. At the lowest speed, the operating noise equates to the sound of a whisper. Whereas on the highest setting, the noise level is equivalent to rainfall. If we talk about numbers, the unit produces a noise level between 31 to 56 dB(A).


The unit has an advanced Swedish design with in-built filter technology to capture 99% of germs, bacteria, and other airborne pollutants. We particularly liked the activated carbon filter since it removed all of the unpleasant odors instantly. Moreover, the unit also has a washable pre-filter and an efficient particle filter to enhance the overall functionality of the unit. The filter replacement indicator just adds to the value of using this unit. You do not have to worry about the filter; the LED warning system will let you know when it is time to replace the filter.


It does a pretty good job of cleaning the air. The pre-filter works perfectly to eliminate the large contaminants. Most users suggest that you need to wash the pre-filter at least once or twice a month for best results. It is completely easy to wash; either vacuum it or wash it in a machine. The particle filter also does a pretty good job of taking care of smaller particles. The efficiency of this filter is 99% and it can wipe out any particle as small as 0.1 microns. Lastly, the activated carbon filter plays a central role to remove smoke, airborne chemicals, smog, and VOCs from the air.


The device gives you a large room coverage and ensures that no contaminants escape. The unit has a cycle of five times an hour in a room as big as 525 square feet. The high air delivery rate also helps to clear out smoke or highly contaminated air from a room.

Final verdict

With a simple and intuitive design and controls, the unit will be perfect for first-time users. It is quiet, effective, and compact. In a nutshell, it is an impressive air purifier that can clean huge rooms within a few hours. It can completely wipe out all traces of odors and pollutants from the air and make the air fresh, clean, and hygienic. Besides, it is available in many colors, which just adds to the aesthetical appeal.
