About

The Blueair Blue Pure 211 is part of the Air purifier test program at Consumer Reports. In our lab tests, Air purifier models like the Blue Pure 211 are rated on multiple criteria, such as those listed below.

Dust/pollen/smoke removal (high): Dust/pollen/smoke removal is how well a model cleared air of fine clay dust and cigarette smoke when operating at its highest speed. A model that scores well for dust removal should perform comparably for pollen.

Dust/pollen/smoke removal (low): Dust/pollen/smoke removal is how well a model cleared air of fine clay dust and cigarette smoke when operating at a low speed that was typically one setting above the lowest speed. Many models have multiple speeds and the lowest is not as effective at cleaning the air. A model that scores well for dust removal should perform comparably for pollen.

Noise (high speed): Noise is based on instrument measurements with the model running at its highest speed.
