With the Stadler Form Eva SF-E-009 Black, you're always up-to-date about the humidity. You can connect the humidifier to a smartphone app. In the app, you can see the exact humidity level. You can control the device remotely via the app with ease. The device humidifies large spaces up to 80m2. There's a separate humidity sensor that measures the humidity very accurately. This way, the humidifier starts working harder automatically when the humidity drops. Thanks to the 6.3L water tank, you don't have to fill it often. You're also less bothered by limescale thanks to the anti-limescale cartridge.
