Winix Zero S at a glance
In short: the Winix Zero S scores 8,1/10 in our air purifier review (from €221). Biggest strength: certified H13 filter. Main compromise: Amazon price fluctuates.
All specifications come from manufacturer data sheets and the Amazon catalogue and were cross-checked before publication. The rating is an editorial overall assessment based on this data; we do not trial products ourselves.
Winix Zero S: what works, what doesn't?
What works well
- Certified H13 filter: 99.999 % separation, the densest filter in the comparison, ideal for strong allergies
- One unit for the whole flat: CADR 410 m³/h also covers 50 m² flats with doors open
- Auto mode with odour sensor: Reacts not only to dust but also to cooking fumes and odours
- Low running costs for its class: Washable pre-filter, main filter only 1× per year
- PlasmaWave can be switched off: The ionisation function can be deactivated for sensitive people
Points of criticism
- Amazon price fluctuates: Currently about €221, at times clearly cheaper in the manufacturer’s shop; compare prices
- No app: No schedules or remote control, only a timer on the unit
- Large & 7.5 kg: 60 cm tall and rather stationary, not a unit to carry around

What does it cost to run?
At a maximum of 70 W power draw, an hour of use at 35 ct/kWh (German electricity price) costs about 2 cents. Eight hours of continuous running (e.g. overnight) therefore cost about 20 cents.
Calculation basis: 35 ct/kWh (German electricity price, 2026, rounded). Values from the manufacturer data sheet; actual costs depend on use and tariff.
Build quality & everyday use
What carries the Winix Zero S in everyday use: certified H13 filter (99.999 % separation, the densest filter in the comparison, ideal for strong allergies) and one unit for the whole flat (CADR 410 m³/h also covers 50 m² flats with doors open). We have to be honest about the weaknesses: Amazon price fluctuates (currently about €221, at times clearly cheaper in the manufacturer’s shop; compare prices).
If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.
