Overview

The Blueair Classic 203 Slim takes up so little space, yet it delivers solid clean-air performance. A great choice for smaller-sized rooms where you and your loved ones want to breathe easy.

Optimal air for medium spaces

Filters the air in a 240 ft² space in about 12.5 min¹ (4.8x an hour, based on AHAM recommended removal rate) to effectively lower particle levels and maintain a comfortable environment in medium spaces like master bedrooms, living rooms, and playrooms.
