Designed for a life with less cleaning

DustMagnet™ air purifier catches 99% of airborne dust before it settles on floors and surfaces. The DustMagnet™ technology attracts airborne dust particles like a magnet thanks to the combination of a unique airflow and charged pre-filters. 5240i is designed to provide you with less dust, more clean air in small to midsized rooms up to 22 m² (5 air changes per hour).

HEPASilent™ Technology

DustMagnet™ uses Blueair's unique HEPASilent™ technology, which allows the air purifiers to deliver more clean air with less noise and less energy. This technology combines electrostatic and mechanical filtration to remove 99,97% of airborne particles such as allergens, dust, pollen, dander, viruses & bacterias, mold, VOCs, and odors. The activated natural carbon effectively removes VOCs, chemicals, and unpleasant household odors.

Designed to blend into your home

With a convenient top surface that doubles as a side table, the air purifier is designed to blend into your home like a great looking piece of Scandinavian furniture with a convenient top surface that doubles as a side table, so there’s no need to hide your air purifier, place it where it will be most effective.

Auto Mode / Stepless fan speed operation

Selecting Auto mode means that your air purifier will automatically adjust when pollution levels creep up. With stepless, variable-speed operation, the fan increases smoothly to the right speed based on the sensor readings and slows down when the air is clean again. This ensures that your air purifier is always running at the perfect speed needed to maintain the air purity in your home.

Accurate filter life calculation

DustMagnet™ uses a proprietary algorithm to accurately calculate the filter lifetime based on usage and pollution levels, ensuring continuous high particle and VOC removal. The filter can last to a maximum of one year. When it is time to replace the filter, the filter indicator on the unit and the Blueair app will send you a notification.

Pre-filters attracts dust like a magnet

Unique to the DustMagnet™ air purifier are the two stainless steel pre-filters that are constantly being positively charged, that effectively attract dust particles just like a magnet. The pre-filters are also cleanable, to significantly extend the lifetime of the main filter.

Whisper silent

Thanks to our proprietory HEPASilent™ filtration technology, DustMagnet™ cleans the air quieter than a whisper 29 dB(A) on the lowest setting and normal conversation 45 dB(A) on the highest.

Unique airflow 

Dual outlet system releases clean air at a precise angle, creating a vortex effect in the room designed to cluster airborne dust particles.

Easy air quality sensor and LED-indicator

The Auto mode function with a smart sensor monitors real-time air quality conditions and auto-adjusts to optimize performance ensuring clean air in your home. Air quality is measured by the concentration of fine particles (PM2.5) in your indoor air. DustMagnet is equipped with a LED air quality indicator (AQI) using a 5 color-scale to identify air quality conditions as excellent (blue), good (green), moderate (yellow), polluted (orange) or very polluted (red). 

Connected Experience with Blueair app

Designed with smart features like Clean air ETA and real-time pollutant tracking, you can be sure your air is always clean. As a user you will have a visual reassurance of the air cleaning progress and estimated time until the air in the room is clean, all thanks to Blueair uniquely developed algorithm that’s tracking multiple parameters in real time. You will also have a dedicated Filter page in the app that will always display filter lifetime and it will guide you on how to order a new filter and how to replace it. With Welcome home feature, the air purifier will start cleaning the air when you are close to getting home in order to welcome you to a healthy home environment, whilst saving energy by not working all day.

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.
