Premium technology of air humidifying

Even such an ingenious invention as the first air humidifier by Venta company founder Fred Hitzler can be improved if clever engineers are passionate about their work.

For example, the innovative patented technology of the AeroStyle makes air humidification faster* and natural pollutant reduction more efficient.

* Compared to the Original LW45 or Comfort Plus LW45.

Innovative evaporation

Every single pane of the new VentWave™ 3D panel stack resembles the model of nature. As on the underside of leaves, thousands of stomata ensure that many more water molecules evaporate in the same period of time than on a flat surface.

Puristic design to feel good

Clean hygiene disc

Our Venta Hygienedisk minimises the cleaning effort for your AeroStyle, decalcifies the tap water, ensures hygienic humidification performance - and makes chemical additives superfluous. The efficient combination of VentWave™ 3D plate stack and hygienic disc is unique and patented for Venta.

Period of use

A minimum of 4 months if operated 24 hours a day with normal calcareous tap water. Our AeroStyle will then show you a change information on the display and in the Venta App.

Clear display

The clearly arranged touch display on the top of your AeroStyle with digital displays and satellite-shaped icons ensures simple, intuitive operation. Four-step operation, automatic and night mode, stand-by - always everything in view. The current room humidity is displayed in the centre.

Control and monitoring via Venta Home App

You can operate your AeroStyle directly on the device. By controlling via Venta Home App from your smartphone (free for Android or iOS) you can control your indoor air data – wherever you are.

Elegant lighting system

The modern aesthetics of your AeroStyle are underlined by a discreet LED light band that can be switched on and off individually, lights up during operation and indicates low water levels by flashing. The Ambient Light LED light strip of your AeroStyle can be easily controlled in the colour of your choice using the available Venta Home App.
