Blueair DustMagnet 5440i Air Purifier

Intelligent engineering blended into a beautiful piece of furniture. Patent-pending technology removes 99% of airborne dust before it settles. All in a single air purifier.

Optimal air for medium spaces
Filters the air in a 33 m² space in about 12.5 min (4.8x an hour, based on AHAM recommended removal rate) or up to 159 m² in one hour on high speed to effectively lower particle levels and maintain a comfortable environment in medium spaces like primary bedrooms, living rooms and playrooms.

Designed for a life with less cleaning
Patent pending DustMagnet™ technology captures 99% of dust before it settles. A dual air intake and vortex airflow pattern keeps airborne dust particles moving, and an electrostatic charge cluster them together. Once inside, dust particles stick to the charged stainless steel pre-filters, just like a magnet​.

Real-time in-app filter tracking
Feature helps to eliminate unnecessary filter replacement with accurate and custom lifetime tracking via an algorithm. Remaining filter life is estimated based on air quality conditions. Generally, recommended filter replacement is between 6-12 months with genuine Blueair filter.


Energy Star rated for efficiency
This certified air purifier uses less energy than an average LED lightbulb (about 10 W) at 7W on lowest setting and up to 42W on high. Confidently run it for quality air 24/7.

Smart device compatible
Use voice control on Amazon Alexa and Google Assistant enabled devices, or the Blueair app, to conveniently do everything from changing your purifier's settings, to putting it in auto mode.

Automatically adjusts to changing conditions
In Auto mode your air purifier will automatically increase fan speed when pollution levels rise in your indoor environment and return to a slower speed once the air is clean.

Night mode supports better sleep quality
When in night mode, your DustMagnet air purifier disables features you don't need while sleeping. This includes the Air Quality Indicator LED light and adjusting to a whisper-quiet low speed of 30dB.

Particle and Carbon Combo-Filter
The DustMagnet™ main filters do not only have a particle filter to remove dust and other fine particles, they also contain carbon particles integrated throughout the filter media to effectively trap VOCs, chemicals and light household odors from pets, cooking, smoking, and more.​ There are two filters, placed each at the top and bottom of the air purifier to ensure optimal removal.
