Dyson Purifier Big+Quiet review: Silently strong

The Dyson Purifier Big+Quiet probably isn't for everyone despite it being a really good air purifier. That's because, as the name suggests, it's really quite big. It's larger than most of the air purifers I've previously tested. Despite the size though, it's actually fairly quiet, even at full power.

As with most Dyson purifiers or fans, the Big+Quiet is bladeless. It features a giant bowl-shaped outlet where the clean air comes out. This sits on top of a cylinder where the filters reside. Both parts come separate in the packaging — you put them together. The filters are also very easy to replace, you just need to push the buttons in the insides of the cylinder to release the filter. Unpurified air goes in from the sides, becomes clean via the filters and comes out through the top. The purifier has three angles of wind flow, 50°, 25°, or 0°. However, it does not rotate. So that means the clean air flow only goes in one direction.

This is unlike the LG PuriCare Air Purifier Pet Mode, which features a rotating fan. I actually prefer that the Big+Quiet could rotate, but perhaps that's in the next version. Still, the air flow is enough to move air around, plus the purifier does have wheels if you need to adjust the direction. There are 10 speed modes, as well as an Auto mode, and as I've mentioned earlier, even at the highest speed, it isn't very loud. It's a soft, quiet hum that's tolerable. The LG Puricare, in comparison, sounds like a jet plane. You can control the speed modes using the MyDyson app, or through a remote control that magnetically attaches to the front.

Speaking of the MyDyson app, it's a pretty handy tool to check the air quality. The Big+Quiet tracks a few more things compared with other purifiers. Most purifiers track the standard PM2.5 and PM10, but the Big+Quiet also adds formaldehyde, CO2, NO2, and VOCs (volatile organic compounds). I like that it tracks CO2, which lets you know that it's a good time to open the windows to let fresh air in. I note that it doesn't track PM1.0 pollutants, but it can filter particulates of up to 0.1 micron in size. The MyDyson app also lets you schedule when the purifier runs, and sends alerts if the air quality isn't good.

At S$1,199, the Dyson Purifier Big+Quiet is quite a bit more expensive than other purifiers. But I think the slight premium is justified by its impressively-quiet operation, and the powerful airflow. Get this from Dyson, Shopee, or Lazada.
