HEPASilent™ Technology: Quieter and Faster

The secret behind the performance of the Blueair Blue Pure 511i Max is the proprietary HEPASilent™ dual filtration technology. By combining mechanical filtration with electrostatic charging, this unit delivers more clean air faster than traditional HEPA filters alone.

• Whisper-Quiet Sleep: Operating at a low of just 19 dB (quieter than a whisper) and never exceeding 48 dB, it is ideal for light sleepers and babies.

• Maximum Efficiency: It uses less energy than a lightbulb, making it sustainable to run 24/7.

• Superior Filtration: Removes 99.97% of airborne particles down to 0.1 microns, including smoke, mold, and dust mites.

Therefore, you get a deeper clean with less noise and lower electricity bills. For optimal performance, ensure you use genuine Filters For Air Purifiers.

Smart Control with the Blueair App

Step into the future of air care. The “i” in Blueair Blue Pure 511i Max stands for intelligent. Connect the device to the Blueair app to unlock features that put you in control.

• RealTrack Filter Monitoring: Stop guessing when to change your filter. The RealTrack algorithm calculates the exact lifetime of your filter based on actual usage and pollution levels (typically 6–9 months).

• Remote Scheduling: Set timers, adjust fan speeds, or activate “Welcome Home” geofencing to clean the air before you arrive.

• Voice Control: Fully compatible with Amazon Alexa for hands-free adjustments.

Customizable Scandinavian Design

Air purifiers shouldn’t be eyesores. The Blueair Blue Pure 511i Max features a unique, washable fabric pre-filter that catches larger particles like pet hair. The unit comes with the stylish “Stockholm Fog” grey pre-filter, but you can customize it with other colors to match your interior.
