The Blueair
Blue Pure 211+ is part of the
Air Purifiers test program at
Consumer Reports. In our lab tests, Room Air Purifiers
models like the Blue Pure 211+ are rated on multiple criteria, such as those
listed below.
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.
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.
Noise (low speed)
Noise is based in instrument measurements with the model running at a low speed. The lowest speed may provide even quieter operation but will not be as effective at cleaning the air.
