Pure Fan Auto




Meticulous design. Effective filtration. Auto-adjusting performance. All in the simplicity of a fan that delivers continuous clean cool for workouts, cooking, office time or sleeping.
Blueair's dual filtration HEPASilent™ filtration technology combines electrostatic charging of particles and mechanical filtration using a unique filter design. When gentle, cooling air is distributed into the room, it is 99%2 free of dust, pollen, pet dander and more.
Refresh a whole space in just 20-30 minutes.²

A remarkable blade structure uses low energy to circulate optimal volumes of purified chill anywhere from too hot kitchens to uncomfortable bedrooms.

Choose from five reusable fabric pre-filter colors to design Pure Fan for your home. Keep colors vibrant with a vacuum, or throw them in the washing machine.


Set to Auto mode, Pure Fan Auto will automatically increase fan speed when particle pollution levels rise, and return to a lower speed once the air is clean.

An AQI, or air quality indicator, uses an LED to display colors for good, moderate, or poor based on the amount of fine, PM2.5, particles an integrated particle sensor finds in your space.

Night mode lulls you to la-la land with noise levels quieter than a whisper, or 25 dB, on low. On high, it's about as disruptive as light conversation at 54 dB.³

Lightweight and easy to move from table to floor with its convenient handle, and a low center of gravity that makes it hard to topple.

Just two buttons lets you choose from on or off, three speed settings, or auto and night mode. It also alerts you to when a new filter is needed.

The LED indicator will turn yellow after 5 months of operation to warn that it's almost time to change the filter. When the indicator light turns red (one month later), it’s time to change the main filter.
