There’s something undeniably satisfying about switching on one of the best Dyson fans when the temperature starts to climb. Dyson’s models are powerful, beautifully designed, and, crucially for me as a hot sleeper, quiet enough to run all night. After testing several Dyson fans back-to-back, one thing became clear: while they might look similar, they definitely don’t perform the same. The tricky thing is that Dyson’s fan line-up has grown considerably in recent years, spanning multiple sizes, designs and feature sets, often with price tags far steeper than rival brands. To put each fan through its paces, I tested airflow using an anemometer and measured noise levels with a decibel meter, both from a consistent distance of 1m, plus I used every model during muggy days and restless summer nights to see how they performed in real life. I also checked energy consumption at the highest settings with a plug-in power meter.’My standout favourite ended up being the Dyson Cool AM07 (£349.99, Boots.com), which strikes that perfect balance between powerful cooling and whisper-quiet performance, without overcomplicating things. Don’t worry, though – if air purification, heating or humidification is your bag, I’ve covered standout models with those features in my roundup too.Read more: Best portable air conditioners, testedThe best Dyson fans for 2026 are:Best overall – Dyson cool AM07: £349.99, Boots.comBest for large homes – Dyson purifier humidify+cool PH2 De-NOx: £699.99, Dyson.co.ukBest desk fan – Dyson cool CF1: £249.99, Dyson.co.ukBest for allergies – Dyson purifier cool PC1: £349, Dyson.co.ukBest for year-round use – Dyson purifier hot+cool HP2 De-NOx: £699.99, Johnlewis.com These fans can cool, heat, and purify your air (Joanne Lewsley/The Independent)Read more: Best air coolers, reviewed
