The Airwasher Method

Our Original LW15 / LW25 / LW45 Airwashers humidify and purify indoor air using only water. There’s no need for additional mats or filters.

As a disk stack rotates in a water tray, clean water evaporates and humidifies the air in the room. This cold evaporation is recognised as the best and most hygienic humidifying method. It is also the most natural way of reducing harmful substances in the air.


Reliable operation

Simply fill your Original Airwasher with fresh tap water to enjoy great air quality. There is even an aromatherapy option. Venta offers six fragrances from relaxing to vitalising.

Easy cleaning

Simply lift the electrical unit and the fan out of the housing in one movement. To clean your Airwasher every 14 days or so, empty out the water, remove any deposits in the tray, rinse the disk stack with water, fill with fresh water and Venta water treatment additive. Job done.

Simple operation

One on/off button, two or three power levels depending on the model, LED status display and automatic switch-off when the water runs out. That’s all the tech your Original Airwasher needs to give you healthy air.
