Designed for a life with less cleaning

DustMagnet™ air purifier quietly catches 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 33 m² (4.8 air changes per hour according to AHAM).

*Refers to the particle collection efficiency of the filter media, only for the air that enters the filter. Based on AHAM AC-1 protocol on removing airborne dust.


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. 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 increase. 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 proprietary HEPASilent™ filtration technology, DustMagnet™ cleans the air quieter than a whisper 30 dB(A) on the lowest setting and normal conversation 49 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 (Estimated time of arrival) 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.
