Innovative Products

Even an ingenious invention like the first Airwasher developed by Fred Hitzler can be improved when smart and dedicated engineers put their minds to it. Now, the innovative technology in the Comfort Plus ensures faster* humidification and more efficient natural reduction of harmful indoor air pollutants. The disk stack rotates in a water tray and releases clean water through evaporative humidification. Simultaneously, harmful pollutants such as house dust and pollen are naturally reduced in the air and are captured in the water inside the humidifier where they remain until you wipe them away.

The Easy Approach to Healthy Indoor Air

Intuitive Touch Display

Tap to switch on or off, and select between three power levels using + and –. Sleep mode dims the display and switches the lowest speed for ultra-quiet operation. Automatic mode will automate the power level based on the current humidity. Thanks to the integrated hydrostat, the display indicates and controls the air humidity in real-time. Controlling your Comfort Plus Humidifier couldn’t be easier.

Natural Reduction of Indoor Air Pollutants

Our LW25 / LW45 Comfort Plus Humidifier models only use water. They do not require any filters to humidify the air and reduce harmful indoor air pollutants. Experts recognize this form of cold evaporation as the best and most hygienic method of humidification as well as the most natural way to reduce harmful pollutants from indoor air.

Reliable Operation

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

Easy Cleaning

Simply lift the electrical unit and the fan out of the housing in one movement. To clean your humidifier every 10-14 days or so, empty out the water, remove any deposits in the tray, rinse the disk stack with water, and fill with fresh water along with Venta Water Treatment Additive. Job done.
