Winix Zero
Clean Performance Index
Based on CADR, noise-to-power ratio, and filter longevity.
Our Verdict
"The Winix Zero is the "old reliable" of the UK market. It offers incredible performance per pound and includes the PlasmaWave technology."
The Staff Take
Winix Zero is the "old reliable". We love the multi-stage filter which is noticeably thicker than Levoit. In our testing, the PlasmaWave feature was surprisingly effective at neutralizing cooking odours rapidly.
