The Winix ZERO N employs 3 stage filtration to remove 99.97% of a range of allergens
The four stage filtration consists of :
- Mesh pre-filter which is washable - captures larger dust particles and fluff so the subsequent filters last longer
- A carbon sheet filter to remove smoke and household odours
- True HEPA filter to remove 99.97% of particles - including allergens, smoke particles, fungi and mould spores, pollen, pet dander, dust and bacteria
Pre-filters in 2 colours
Pre-filters capture the larger particles extending the life of the main filters. Each unit comes with a pre filter in either grey or beige that you can change depending on mood or decor. Winix reccomends cleaning the pre-filter once every 14 days, which may vary depending on the air quality. Please see the manual for instructions.
Features Auto Mode function based on the unit's air quality particle
On automatic mode the fan is automatically adjusted when the air quality sensor detects new pollutants or worsening indoor air quality. When the air quality sensor is on the LED light will indicate the current indoor air quality via three lights: blue, amber or red.
Three speed settings
Three speed settings: low, medium and high.
Particle Sensor care
In order to maintain performance, the particle sensor needs to be cleaned every two months or more frequently when the unit is running in a place with high dust levels. Please review the manual for instructions.
Economical running costs
The Winix ZERO N is very economical to run with a maximum of 40W power consumption.
