Blueair Blue Pure 311i Max

B Business Insider Lauren Allain · reviewer · Jul 2026

The Blueair Blue Pure 311i Max offered the best combination of low noise without compromising performance. Blueair says the 311i Max operates at as low as 23 decibels, but in our testing, it was even quieter, reaching just 21 decibels on its lowest setting. At that speed, I had to double-check that the air purifier was still powered on.
