About

The Fellowes AP-300PH is part of the Air purifier test program at Consumer Reports. In our lab tests, Air purifier models like the AP-300PH 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.
