The Blue Max 3450i is equipped with Blueair’s unique HEPASilent™ filtration technology delivering maximum filtration² with minimum noise³ which 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 Max filter also reduces unpleasant household odours and smoke.

HEPASilent™ dual filtration technology delivers more clean air faster and uses less noise and energy than HEPA filtration alone.

Whisper Silent / Quiet
Quiet Mark Certified, Blue Max products now come with a specially engineered noise shield, which helps ensure you get powerful performance without compromising on noise, this means you can place it anywhere in the room. Quieter than a whisper at 23dB(A) 

Simply smart 
This Blue Max 3450i version comes with an intuitive display, auto mode (with 5 color air quality indicator), app control, scheduling, outdoor air quality, and filter tracking with RealTrack algorithm. Blue Max also has Alexa compatibility, and a Welcome home/geofencing technology, so you’re in control of your air quality.

Unique design - Seamlessly fits/blend into your home
The 3450i 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 3350i 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 4W – 38W for  this 3450i)

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.

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.

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.



[1] Comparing pollen CADR on high fan speed, other units may vary. Based on AHAM maximum allowable certified rating which may vary from the AHAM seal claimed valued.

[2] Comparing CADR performance of Blueair models with mechanical and electrostatic filtration vs same models with only H13 HEPA mechanical filtration.

[3] 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.

AHAM certified room size is the size of room in which the air purifier can provide a full five air changes per hour. Therefore refreshing all of the air in the room through its filters once every twelve minutes.This is more relevant than 'maximum' room size which does not reflect an air purifiers genuine effective capability. Always be sure to only use the 'AHAM certified' room size for true comparison purposes.
CADR stands for Clean Air Delivery Rate and is an actual measurement of the amount of filtered air provided by the machine.This is the only true way to compare like for like between air purifiers when assessing how powerful they are. CADR is not the same as air volume which will always appear higher due to the fact that it is only a measurement of the units fan power (with no filter Installed).
***Carbon Filters
Carbon filters remove chemical fumes including VOC's, traffic combustion gases, pet odours, tobacco smoke and many more gaseous pollutants.However not all carbon filters are the same. Basic carbon 'sheet' filters are generally lightweight and have little capacity to adsorb these pollutants effectively. On the other hand filters containing actual carbon 'granules' are infinitely more effective and should always be chosen over carbon sheets where the most effective gaseous pollutant removal is required.
Due to continuous development and improvement, the manufacturer reserves the right to change the specification of the product or its performance,or the contents of the guide, without notice.
