Blueair Blue Pure 311i Max

The Blue Pure 311i Max combines Swedish design with robust performance for medium-sized rooms. Its three-part filtration includes a machine-washable fabric pre-filter (available in colors), a particle filter, and a carbon filter for odors. Key features are whisper-quiet operation on lower settings, one-button control, and smart functionality via the Blueair app for scheduling and monitoring.

It's ideal for bedrooms, offices, or living rooms where discreet, effective purification is needed. It ranks highly for its excellent value, low energy consumption, user-friendly maintenance, and the added convenience of smart features over its non-smart predecessor.
