Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
Coverage on these listings mixes m² and sq ft, and the AIRTOK and GoveeLife define theirs as cleaning the area once per hour, so CADR in m³/h is the figure five of the six give in the same unit. Three of the six state a warranty term, and two, the Winix and Avalla, give power use in watts. The Winix title and feature list state up to 99m², while its product details give a different figure, upp till 360 m².
Our Take
The WINIX 5500-2 is the default pick for a large room, with a 390 m³/h CADR, coverage up to 99m², auto mode and a 3-year warranty on the listing. Choose the Avalla R-2200 for a 250m³/h CADR with a 24-month parts and labour warranty, or the GoveeLife for App and Alexa control.
