The Winix Zero S - helps you live a healthier life

The Winix Zero S takes care of most airborne pollutants that you can find in your home today. Equipped with tried and tested 4-stage air purification system, it cleans the air from allergens, fine dust (PM2.5), pet dander, cigarette smoke, mould spores, harmful VOCs, and unpleasant household odours. The Winix Zero air purifiers do not produce any harmful ozone, so they are very safe for people with sensitive airways, babies, and young children. The Winix Zero S performs well in rooms up to 49 m2  

Scientifically tested and certified by the ECARF and the Allergy UK

The Winix Zero S has been rigorously tested and certified by the ECARF (European Centre for Allergy Research Foundation) and the Allergy UK. This means that this is the appliance that you can trust to clean the air in your home and relieve your symptoms caused by allergies to airborne particles.

4-stage air filtration removes a wide range of airborne pollutants

The tried and tested 4-stage filtration comprises a washable pre-filter, a granulated activated carbon filter, a long-life True-HEPA filter and the PlasmaWave® technology.

Stage 1: The pre-filter captures large dust particles to enhance the performance of other filters and make them last longer. 

Stage 2: The granulated activated carbon filter traps organic particles from the air that can arise from cooking, pets, cigarette smoke and other household odours.

Stage 3: The H13 True-HEPA filter removes 99.97% of all particles in the air up to 0.3 microns, such as fine dust, allergens, viruses, bacteria, fungi, mould spores and pollen.

Stage 4: The Winix PlasmaWave® technology creates hydroxyl molecules that neutralise viruses, bacteria, and gases naturally, producing no harmful ozoneThis technology meets the California Air Resources Board’s AB 2276 standard, which is the most rigorous American certification benchmark for indoor air cleaning ozone emissions. The PlasmaWave® technology can be switched on or off as desired.

"Energy Star" certified

The Winix Zero S meets strict energy-efficiency requirements set by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). It means that it uses less energy compared to traditional non-certified air cleaners, saving you money. As a result, it consumes an impressively low 3 watts of power when running in "sleep" mode. 

The "Auto" mode ensures that your air is always clean

The Winix Zero S features the "Auto" mode and the built-in smart sensor that measures current air quality and adjusts the speed of the fan (low, medium, high, or turbo) according to the particle amount in the air. The LED light on top of the unit changes in real-time based on the air quality in your room (blue - good, amber - fair and red - poor).

The Winix Zero S will alert you when it is time to replace the filters. On average, depending on the environment, the life expectancy of the filters is approximately 12 months.

Whisper-quiet "sleep" mode for healthy air without distractions

The Zero S features a light sensor that automatically switches the air purifier into the whisper-quiet "sleep" mode as soon as it gets dark. In this mode, the air purifier cleans the air at a noise level of as low as 27 dB (A), helping you breathe and sleep better and feel more energetic in the mornings.  

Multiple design awards winner that looks good in any room

Beyond its fantastic air-purifying capabilities, the Winix Zero S has won multiple design awards, including the iF Design Award and the Red Dot Design Award. With its clean lines and modern design, this stylish air purifier will look good in any room.
