CR's Take
Overall, the Carrier RMAP-ST is very good at removing dust, smoke, and pollen. At the highest speed, which is important for quickly cleaning the air in the room, its air-cleaning performance is very good, but the unit is fairly loud. While running at a low speed, which matters if you’ll run the unit in your bedroom at night, its air-cleaning performance is adequate, and the unit is somewhat loud. In our testing, we also consider how easy it is to operate the controls, carry it, and clean or replace its filter(s), and this model does a solid job. Additionally, its annual usage cost is estimated at $127 (approximately $27 in electricity and $100 in replacement filters).About Consumer Reports
