Detailed Test Results

Mediocre at removing dust, smoke, and pollen from a room’s air when run at its highest speed, and less effective at low speed. This model runs quietly on its lowest speed but was somewhat noisy (though average) on its highest speed.

About

Overall score for the Alen T500 Pure + Black is mainly how well the model removed dust and smoke from a test chamber, plus quietness for room purifiers.
Dust/pollen/smoke removal: How well models cleared air of fine clay dust and cigarette smoke; performance of portables is at their highest and lower 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.
