Anti-calcification system: Calcium is deposited in both the shower head and the automatic cleaning system. The same happens with the faucet, where silicon collects. The integrated air cleaner has an anti-calcification system that also prevents the device from being calcified internally.
Anti-backflow system: This system prevents dirty water from being drawn into the clean water pipe and consists of a layer of material. Equipment equipped with an anti-backflow system will display the DVGM pass mark on the surface of the package.
