Detailed Test Results

Impressive at removing dust, smoke, and pollen from a room’s air when run at its highest speed, but less effective at low speed. This model runs quietly on its lowest speed but was somewhat noisy (though average) on its highest speed. Easy to operate its controls, carry it, and clean or replace its filter(s). This whole-house air purifier allowed air to flow through it fairly easily.

About

Dust/pollen/smoke removal: How well models cleared air of fine clay dust and cigarette smoke; performance of portables is at their highest and lowest speeds. Ones that scored well for dust removal should perform comparably for pollen.
Noise: Based on instrument measurements with a portable model running at its highest and lowest speeds.
