Blue Pure 211i Max

Full review

The Blueair Blue Pure 211i Max is a smart air purifier built for large rooms and open living spaces. It combines high airflow with Blueair’s HEPASilent filtration, app controls, real-time air quality monitoring, and automatic fan adjustment. Blueair recommends it for rooms up to 674 sq. ft. at 4.8 air changes per hour, while independent testing also shows strong particle-cleaning performance. In this review, we look at its filtration, noise, features, running costs, and overall value.
