![]() If you want the purifier to turn off automatically, then remember to set this as a schedule option. ![]() I recommend this, since the unit can only capture dirt when it’s on. There’s also scheduling functionality, so the Blueair DustMagnet 5440i can run automatically. Via the app, you can access the same range of controls as appear on the device itself, although there’s a wider choice of manual fan speeds. It would make more sense for the lights to come on for a few seconds when the corresponding physical button has been pressed before returning to the light level I’d set. That’s useful for getting rid of unwanted ambient light, but there’s a slight flaw: it makes using the on-device controls difficult, since the switches no longer light up to confirm that they’ve been pressed. With the app, I could turn off (or down) the lights on the purifier. It doesn’t make a difference in terms of how the unit operates, but it’s a little frustrating. However, I found that my app kept updating my location and then moving my Blueair DustMagnet 5440i to a slightly different address: usually next door, or over the road. That’s potentially useful if you have multiple homes. When it first launches, the app lets you set multiple locations and assign products to them. This is a smart air purifier that connects to Wi-Fi and can be controlled through the Blueair app. If you want an air purifier that’s more reactive to a wider range of pollutants, you’ll need to consider a model such as the Dyson Purifier Hot+Cool Formaldehyde. This is the only sensor on the Blueair DustMagnet 5440i, so while it will adjust to dust, it won’t pick up levels of gasses or VOCs. The latter uses the PM2.5 dust sensor to automatically adjust fan speed depending on the level of very small particles in the air. You’ll find a basic set of controls on the top of the Blueair DustMagnet 5440i, with a choice of three manual fan speeds (min, medium and max), plus a nighttime mode and an automatic mode. By choosing such filters, the fan can operate more slowly (and efficiently), which also cuts down on any noise generated – handy for a device that’s designed to run all of the time in areas such as bedrooms. There’s a status light on the machine, plus you’ll receive a warning through the app when it’s time to replace the filters.īlueair doesn’t use HEPA technology instead it includes less dense filters that it says are just as effective.

Then, there are the replaceable filters, which trap dust, VOCs, smoke, pet dander and bacteria and viruses. It’s recommended that these are cleaned every couple of weeks or so. Both have a mesh pre-filter that can be cleaned using a vacuum, which will capture hair and larger particles. In this model, there are two sets of filters: one at the top and one at the bottom. The Blueair DustMagnet 5440i that I have here is designed for medium spaces (think bedrooms and kitchens), but there’s also the 5410i, which is the same size but has a plainer, plastic finish, and the 5210i (plain finish) and the 5240i (material finish) for smaller rooms. There are actually four versions of the product available. It’s a similar idea to the table version of the Ikea Starkvind. On top is a small tray, turning the purifier into a side table. Its soft material finish completes the look, helping it to fade into the background.

The Blueair DustMagnet 5440i offers a vast improvement and is designed to easily fit into the home. When I reviewed the Blueair Classic 405, I was impressed by its power but its industrial metal casing was less desirable. A slightly fiddly app and on-device controls are minor drawbacks. While the Blueair DustMagnet 5440i works like other air purifiers, it’s also designed to suck up dust, doing away with the need to vacuum as often.Īnd it works brilliantly in this capacity, working away in the background to reduce the amount of visible dust. For those who don’t have allergies or suffer from breathing problems, clean air is still better, but it’s harder to quantify and actually appreciate the difference it makes. Most air purifiers are built to clean the air, making it better to breathe.
