Blue Pure 211i Max Review (2026): Big Airflow, Light Build

This Blue Pure 211i Max review finds a light purifier that moves a lot of air for its size and price. It pushed about 410 CFM of airflow at under 16 lb, according to Consumer Analysis, a YouTube channel that tests air purifiers, which also found it quiet for that airflow.

The catch is filters: Consumer Analysis put them at about $70 every 6 to 9 months, or about $93 a year. The French Glow, a YouTube channel that reviews home products, noted thicker filters and PM1 to PM10 sensors compared with the older Blueair 211.

It listed at $244.99 on Amazon on Oct 16, 2026, with a 4.7 rating from 3,666 ratings. Wirecutter lists it as its upgrade pick.

What YouTube Reviewers Found With the Blue Pure 211i Max

These findings are paraphrased from the video transcripts and credited to each creator. They are the creators’ own test results and opinions, not mine.

• Consumer Analysis (Blue Pure 211i Max): about 410 CFM of airflow at under 16 lb, very good energy efficiency and low noise for that airflow (68.2 dB on high). It rated coverage at roughly 500 sq ft.
• Consumer Analysis: downsides are the exposed fabric pre-filter, which shows debris and wear, a proprietary particle filter instead of true HEPA, a thin foam carbon layer, and filter costs of about $70 every 6 to 9 months, or about $93 a year.
• The French Glow: compared with the older Blueair 211, the 211i Max has thicker filters, sensors for PM1, PM2.5 and PM10, and a larger turbine, drawing about 46 W. The filter is protected only by the cloth pre-filter, so kids or pets can squish it.
