The device cleaner naturally removes limescale and stubborn dirt using the highly effective lime removers from lemon. This saves you the hassle of thoroughly cleaning your air washer, leaving your device looking almost like new. The high-quality cleaner is manufactured and filled exclusively in Germany under strict quality standards. It is environmentally friendly, mild, odorless, colorless, and well biodegradable, allowing you to dispose of it safely via wastewater. With regular use of the device cleaner (recommended every 6 months for year-round use), you can ensure the hygienic operation of your air washer and support its long lifespan. Since the mild cleaner is specifically tailored to Venta air washers and the plastics used, it keeps the material undamaged. If you plan to not use your air washer for an extended period, you should also use the device cleaner before storing the Venta device to ensure that all residues are removed. The Venta device cleaner has been developed for the regular cleaning of the following Venta devices: Air Washer Original LW15 / LW25 / LW45, Air Washer Comfort Plus LW25 / LW45, Air Washer App Control LW60T WiFi and Hybrid App Control LPH60 WiFi, Air Washer AeroStyle LW73 / LW74, Air Washer Professional AW902, and Hybrid Professional AH902.
