Open-Box: Blueair Blue Pure 311i Max Air Purifier

The Blueair Blue Pure 311i Max Air Purifier cleans your air better, faster, and smarter than ever before. This Energy Star-rated unit is also zero ozone verified, running efficiently and without adding ozone to your indoor air.

The washable pre-filter extends the life of the primary filters by capturing large particles, and comes in subtle Stockholm Fog gray. It’s also available in three other muted shades (purchased separately) to fit your home’s style.

Cleaner Air for Better Health

• HEPASilent™ Technology: Fast air cleaning of 387 sq. ft. in 12.5 minutes or up to 929 sq. ft. in 30 minutes.
• Air Quality Indicator: Five colors are used to visually reflect the level of your air quality. Particle sensor detects pollution so the reading is based on the concentration of fine (PM2.5) particles in the space.
• RealTrack Technology: This proprietary algorithm tracks filter usage accurately, adjusting the calculations based on your unique environment, factors like fan speed, usage time, and pollution levels. And because this filter lasts 6-9 months, you’ll be able to reorder a new filter less often, and in plenty of time.

Quiet Operation with Multiple Speeds & Wi-Fi

The Blueair Blue Pure 311i Max allows you to select low, medium, or high speed to fit the need. You can also adjust the brightness levels and enable the child lock with two simple buttons.

• Auto Mode: Automatically adjust the fan speed based on the 2.5PM indoor level to ensure optimal air quality.
• Night Mode: Sets the unit on the lowest fan speed and fully dimmed lights.
• Wi-Fi Connected: Set up the Blue Pure 311i Max on your Wi-Fi and use the Blueair App to adjust settings, track the filter, and more.

Operating quietly, this unobtrusive air purifier runs at only 23 dB on low and has a maximum sound level of 50 dB.
