Unique design - Seamlessly fits/blend into your home
The 3250i has interchangeable premium fabric pre-filters inspired by Scandinavian nature, Blue Max is designed to fit your personal style. Choose from five pre-filter colours, which extend the life of the primary filter,s catching large airborne particles such as dust, lint, pollen, and pet hair. The 3250i comes with the Stockholm Fog (dark grey) pre-filter, also available by seperate purchase are Hälsinge Moss (green), Västkust Sand (pink), Gotland Limestone (beige) and Kattegatt Seabed (blue).
The premium fabric doubles as a pre-filter, catching large particles - vacuum the fabric or toss it in the washing machine (40°) whenever it needs cleaning.
Air quality sensor and LED-indicator
Air quality is measured by the concentration of fine particles (PM2.5) in your indoor air. Blue Max air purifier's LED air quality indicator (AQI) uses a 5 colour-scale to identify air quality conditions as excellent, good, moderate, polluted or very polluted.
Ease of use / 4 fan speed modes in a two-button control
Blue Max has a simple two-button control (on/off and 4 speed settings to auto, child lock and night mode). With a large 360° intake and a lightweight, compact design, you can place the Blue Max air purifier anywhere in your room without compromising performance. Equipped with a sensor that automatically adjusts to real-time air quality conditions to ensure clean air is delivered to your room. On Night mode the air purifier operates quietly at a low speed and dimmed LED lights.
Uses less energy than a light bulb
Energy Star Most Efficient 2023 (USA); Blueair air purifiers use HEPASilent™ technology which delivers more clean air with less energy than a LED lightbulb on low. (as low as 2.5W – 20W for this 3250i)
Blue Max filter
The improved filter structure with four layers of filtration effectively filters high volumes of air while removing pollutants like allergens, pet dander, dust mites, fine particles, mould, pollen, viruses & bacteria. The large surface area of the filter means more particles are captured, while activated natural coconut carbon reduces gases and household odours.
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.
Greater Filter lifetime
The new Blue Max comes with an upgraded filter which prolongs the filter lifetime by up to 50% compared to the previous model. We recommend replacing the main filter every 6-9 months when used 24 hours a day and cleaning the pre-filter fabric as needed to maintain optimal performance.
 Comparing pollen CADR on high fan speed (Blue 3250 auto & 3250i vs. Blue 3210), other units may vary. Based on AHAM maximum allowable certified rating which may vary from the AHAM seal claimed valued.
 Comparing CADR performance of Blueair models with mechanical and electrostatic filtration vs same models with only H13 HEPA mechanical filtration.
 When equivalent CADR was measured, Blueair model with mechanical and electrostatic filtration achieved less noise with less energy than same model with only H13 HEPA mechanical filtration. The lower noise refers to the difference in sound power levels (dB(A)). Performance may vary.
