The best fans to keep you cool in 2026 – tried and tested

As heatwaves intensify, a new review identifies the AirCraft Lume as the most energy-efficient overall fan, capable of running for 56 hours on its top setting for the same electricity cost as one hour of air conditioning [1]. The review tested 15 models for size, noise, power use, and cooling effectiveness [1]. A typical portable air conditioner uses 1,000W, costing about 26p per hour to run, while the tested fans ranged from 8W to 60W [1]. The top-rated AirCraft Lume uses 18W on its highest setting [1]. Other notable models include the budget Devola desk fan, which uses 16W and produces an air speed of 4m/s with a peak noise of 50dB [1]. The versatile Shark FlexBreeze Pro Mist fan uses 14W on its top fan setting and offers a cordless, misting option for outdoor use [1]. The Dreo Cruiser TF518, a tower fan, was measured at 60dB from a meter away despite a claimed 'silent' rating of 25dB [1]. The push for efficient cooling technology comes as global temperatures rise, increasing reliance on electrical appliances [1]. The tested fans represent a consumer shift toward lower-energy alternatives, a trend mirrored in other sectors adapting to environmental pressures [2][3]. All non-returned units from the test were donated to the charity Furnishing Futures [1].
