Hands-on review: Blueair Blue Pure Purifying Fan

Combination fan and air purifier with a distinctive look that gives it a Wow! factor.

This Swedish-designed fan purifies air as it blows. It sets its sights squarely on the market Dyson has carved out for stylish air-purifying fans.

Where most Dysons only filter some of the air they put out (because of their clever ‘air multiplier design’), the Blueair filters it all. It’s able to remove more than 99 per cent of airborne dust and pollen particles in a 28m³ room in just 20 minutes.

It’s truly beautifully designed, with an attractive front pattern and no exposed blades to catch dust (or fingers). People see it and say “Wow!”, more so than pretty much any other fan. It’s a cube, so it has a larger footprint than the Dyson’s but a low centre of gravity, which makes it very stable. But the bigger footprint means it belongs on the floor; it would take up an entire bedside table.

The brown synthetic leather strap handle on top is elegant. The fan’s four rubber feet match its colour and are very practical: they won’t slip and they don’t mark the floor.

The fan is ready to use straight out of the box and its controls are very simple and intuitive. The big white plastic circle on the top is touch sensitive. Tap it to cycle the power from off to 1, 2 or 3. Subtle lights indicate power level. The lights dim to 10 per cent after seven seconds, so they don’t disturb you in the night. It doesn’t oscillate but the air is dispersed across a wide angle of 90 degrees.

The downside to the fan’s simplicity is that there’s no remote control, no companion app and no air-quality monitoring. And it’s definitely a fan, not just an air purifier. At level 1, it’s whisper quiet, you’ll hardly notice the sound among life’s background hum. At 2 it’s noticeable, but you get used to it. At 3 it’s loud, even if you’re at the other end of the room. That could be handy if white noise lulls you to sleep though.

All air passes first through a washable pre-filter that stretches over the back. You get two – blue and grey. Each is a small fabric mesh that looks like a hairnet. The colour changes the look at the back, but that’s not paramount as, unless you live in an open-plan apartment, people are unlikely to see the back much.

Having two pre-filters is good though, because they’re washable: Blueair recommends vacuuming or washing occasionally (you can even machine wash them on low). The mesh filter looks like cats could scratch it, but my three feline destruction-testers showed no interest in doing so.

Next the air passes through a particle filter inside, which lasts around six months and is simple to replace. A light on the top of the fan turns yellow after five months to alert you to buy a new filter, then red after six months to change it.

The tech specs are good in terms of air purification. It offers a CADR (clean air delivery rate) of 300m³/h for pollen (presumably on the top setting) with a filter efficiency of 3 microns. Third-party testing showed that it removed more than 99 per cent of dust and pollen particles in a 28m³ room in 20 minutes.

In all, the Blueair Blue Pure Fan is a great buy if you want a cooling fan that also offers decent air purification. It’s beautiful, a great fan and it filters the air. But if you just want an air purifier then the Blueair Blue Pure 411 (details below) is half the price, offers a CADR of 220m³/h for pollen, which is enough for most rooms, and is quieter.

Most Dyson fans use an ‘air multiplier’ to increase the amount of air they throw at you. Clever, but it means only some of that air is filtered. This smaller model, however, filters all air through an activated-carbon and glass HEPA filter. It’s good for creating a purified breeze at your bedside or desk.

An air filter but not a fan, this compact machine looks good and can clean the air in a 15m² room completely five times an hour using mechanical and electrostatic filtration. It catches airborne particles including dust, pollen, smoke, viruses and bacteria, while active carbon removes odours.

This larger, pricier Dyson is the only model here that acts as a fan heater as well as a fan. Its ‘air multiplier’ blows filtered air out of a slit around a large oval hoop, which in turn pulls more unfiltered air through the middle. Its display and app monitor air quality and temperature. Activated carbon and glass HEPA filter.
