The Levoit
PlasmaPro 600S is part of the
Air Purifiers test program at
Consumer Reports. In our lab tests, Room Air Purifiers
models like the PlasmaPro 600S 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.
