When it comes to price, accessories, and sheer power, there's a clear winner in the battle of the portable fans.

Big on purification and low on noise, but the Coway Airmega 350 is held back by no Wi-Fi and a slightly cheap build.

We put Dyson's smallest-ever purifier to the test to see if its jet engine-inspired technology can still deliver whole-room purification despite its compact size.

The new Dyson Hot+Cool HF1 has fantastic smart features, but a couple of drawbacks may mean it’s not for you.

It's hard to believe that something so beautiful can be so functional and efficient.

I’ve been testing the most attractive large-room air purifier you can buy right now, and it’s surprisingly good value for money.

The original TurboBlade blew me away, but I'm not quite as hot on the warming function Shark has added for the Cool + Heat version.

After more than two years of use, I'm still impressed by the Levoit EverestAir's ability to clean air efficiently and get rid of odors.

The Dreame AirPursue PM20 is big, but it more than earns its floor space with advanced purification powers, plus cooling and heating functions.

An air purifier that’ll hold my keys, charge my phone, and switch up the ambience? Yes please.

Strong yet surprisingly quiet, this versatile air circulator has me seriously impressed.

Offering efficient heating, cooling, and air purifying in a compact package, this little Dyson has a lot to offer.

A quiet, powerful fan with smart connectivity and optional battery power, the Duux Whisper Flex 2 is a premium fan for those who want airflow with a touch of subtlety.
