The Winix ZERO N is a modern and stylish air purifier, suitable for use in rooms up to 45 m² in size. As a result, it performs well when used in medium-sized spaces such as living rooms, kitchens and bedrooms.
The Winix ZERO N excels at removing a wide range of pollutants from the surrounding air supply, and it can effectively trap particles down to 0.3 microns in size.
Therefore, it reduces the pollution levels of many common contaminants, including:
To remove so many pollutants, the ZERO N uses a three-stage method that starts with a washable pre-filter and ends with a high-quality True HEPA filter.
For best results, Winix recommends washing the pre-filter every 14 days and replacing the carbon filter every 3 months. Finally, the HEPA filter needs replacing whenever the “Check Filter” indicator lights up on the interface.
In our experience, the Winix ZERO N’s three-stage system is effective at removing many common pollutants. However, it shines best when used in combination with the inbuilt particle sensor through AUTO mode.
When set to AUTO mode, the ZERO N can independently alter its fan speed based on the detected air quality. Therefore, during periods of low air quality, it can increase the speed setting to reduce pollutant levels swiftly.
Additionally, the unit converts the air quality information it gathers into one of three levels. An LED indicator then displays the corresponding level by changing its colour to either blue, amber or red.
Rounding out the filtration package offered by the ZERO N is the ability to alter the fan speed. There are a total of three settings available, and the highest level, “High”, offers the best filtration performance.
When used on the “High” setting, the ZERO N can produce a particle CADR of 168 m3/h.
Additionally, in rooms sized 45 m², it can complete a full air change in an hour. However, the air change rate will be faster in smaller spaces. For example, in rooms up to 14 m², it can complete five full air changes in an hour.
One great advantage of the Winix ZERO N is the intuitive touch interface. Designed to be easy for anybody to use, it allows for quick and complete control over the unit in a couple of taps.
Balancing utility and simplicity, Winix has done a great job keeping the interface free from clutter. However, the minimal design still features a full set of buttons for every function and feature.
As a result, it’s easy to change settings for fan speeds and operation modes or digest useful information about the surrounding air quality.
Beyond being easy to use, the ZERO N is quiet when active. While operating at its lowest fan speed, it only produces 26 dB of noise. That’s equivalent to the sound of rustling leaves, making it suitable for use at nighttime.
Even at its fastest fan speed setting, it only produces 47 dB of noise, which is comparable to the sound of a quiet conversation. Overall, our experience has shown it to be good at staying quiet while it does its job.
Matching those quiet noise levels, the ZERO N is also power efficient. When active, it only requires a maximum of 40 watts of power. As a result, it isn’t expensive to run, even for long periods.
We also have to credit the ZERO N’s modern aesthetic, which is very clean and pleasing to the eye. Additionally, it offers top performance while remaining very slim and can easily blend into a room when placed against a wall without any limitations.
Last but not least, the Winix ZERO N is certified by multiple industry bodies, including AHAM (Association of Home Appliance Manufacturers), ECARF (European Centre for Allergy Research Foundation) and Allergy UK.
Therefore, it can help to alleviate symptoms caused by strong allergies to airborne particles such as dust or pollen.
