Clean air at the touch of a button

High performance, easy usage and good looks make the new Blue 3210 air purifier a great choice for people who want to breathe clean indoor air. This purifier combines plug and play simplicity with signature Blueair performance, giving you clean air at the touch of a button. Simply push the one button control and Blue will automatically adjust to give you more clean air with less noise and less energy. With a tiny footprint and very low noise levels, this makes it ideal to place in smaller rooms such as bedrooms up to 17 m² (5 air changes per hour according to AHAM).

HEPASilent™ technology

Blue 3210 is equipped with Blueair's unique HEPASilent™ filtration technology that effectively removes 99,97% of particles such as allergens, dust, pollen, dander, mould while quietly creating a clean indoor environment for you and your loved ones. The carbon mesh in the Blue filter also reduce unpleasant household odours and smoke.

Whisper silent

Blue 3210 is whisper silent, which means you can place it anywhere. Quieter than a whisper 18 dB(A) on the lowest setting and normal conversation 48 dB(A) on the highest.

Uses less energy than a lightbulb

HEPASilent™ technology delivers more clean air using less energy than a lightbulb. Even on the highest setting, the Blue 3210 air purifier only uses 10W and 2W on the lowest setting.

Air quality sensor and LED-indicator

Air quality is measured by the concentration of fine particles (PM2.5) in your indoor air. Blue air purifier's LED air quality indicator (AQI) uses a 3 colour-scale to identify air quality conditions as good, moderate or polluted. With just a quick push of a button you can easily check how the Blue air purifier is running. Gently glows white to indicate selected fan speed and will change to red, letting you know when it is time to change the filter.

4 fan speed modes in one-button control

Press once for Auto mode, twice for Night mode, three times for Everyday mode, and four times for Boost mode. Equipped with a sensor that automatically adjusts to real-time air quality conditions to ensure clean air at the touch of a button on Auto mode. On Night mode the air purifier operates quietly at a low speed and dimmed LED lights.

Simple to place

With a large 360° intake, you can place the Blue air purifier anywhere in your room without compromising performance.

Stylish pre-filters to fit your personal style

With interchangeable premium pre-filters inspired by Scandinavian nature, Blue is designed to fit your personal style. Included is the Arctic trail (dark grey) pre-filter, but also available are Winter reed (light grey), Archipelago sand (pink), Aurora light (green) or Night waves (blue). The premium fabric doubles as a pre-filter, catching large particles and extending the life of the primary filter - vacuum the fabric or toss it in the washing machine (40°) whenever it needs cleaning. The pre-filters smart design also allows to cover the cord and hide it.

Foldable 360° filter

Blueair's unique, patented foldable frame solution reduces over half of the packaging volume –saving heavily on transport and storage. Designed to have the largest surface area of the filter possible, so more particles get captured.

Filter lifetime

We recommend replacing the main filter every 6-months when used 24 hours a day and cleaning the pre-filter fabric as needed to maintain optimal performance.
