TEST: Blueair Dust Magnet 5440i – neat and efficient dust collector

Blueair is a well-known manufacturer of air purifiers and previous models we tested have performed convincingly. We have now received the recently launched Dustmagnet 5440i and as the name suggests, it should be able to catch airborne dust before it settles on floors and other surfaces.

Really nice design

The taste is like the butt, but if you ask us, the Dustmagnet 5440i is without a doubt the manufacturer’s currently most stylish model. It is more like a trendy side table than an air purifier and the fact is that thanks to its smart design it can be used just as such – while it cleans your home environment from dust, pollen and other particles.

The dust magnet 5440i has not only one main filter, but two – one at the top of the unit, one at the bottom – consisting of combined particulate and carbon filters. These are placed in a pull-out pre-filter in stainless steel, and it is precisely these pre-filters that make the Dustmagnet models unique. Namely, they are constantly positively charged and in combination with the unit’s air flow, this should result in the air purifier actively attracting airborne dust particles before they settle on floors and other surfaces.

It is unfortunately difficult for us to check if the function is as efficient as promised as we lack the optical measuring instruments that are required for this, but if we go for a clean feeling, we experience no noticeable reduction of dust on either furniture or floors compared with when we have tested other air purifiers.

Flexible app, easy installation

Installation is simple. Via bluetooth and the associated app, the device is found quickly, after which you then connect it to your home wireless network. In the app, you can then control the air purifier speed, see filter status and schedule the air purification of your home. You can also use the “welcome home” function, which means that the unit goes into sleep mode when you leave the home to switch on again to clean the air just before you return home. Smart and environmentally friendly!

Of course, it is also possible to use the function buttons on the air purifier itself to set the desired power mode. In addition to three manual modes, there is a night mode and an auto mode where the fan speed is adjusted automatically depending on current pollution levels.

Maintenance is minimal, except that the main filter must of course be replaced at regular intervals, it does not require much of you as a user for the air purifier to work. Pull out and vacuum the pre-filter from time to time, you do not need to do more than that.

In our particle measurements *, the Blueair 5440i performs really well. After half an hour of operation in our previously “uncleaned” reference room, our particle counter reports a drastic reduction of pollutants in the air. PM2.5 was reduced from 199 to under 14, PM5 from 49 to 5 and PM10 from 31 to 1. That is, without a doubt with praise approved.

* To test air purifiers, we use an advanced particle counter, PCE Instruments PCE-PCO 1 borrowed from Conrad.se. All air purifiers are tested in the same environment. The first measurement takes place in an unclean room (20 m²), then we let the air purifier run at maximum level for half an hour, after which the next measurement is performed. The values ​​should be seen as an indication when the measurements are performed in a home environment and not in a clinically optimal test environment.
