The Anti-Calc System is a system that helps maintain cleanliness of the hand shower nozzles or rain overhead shower and ensure them better permeability. It usually comprises a system of small rubber cornets which automatically decalcify the nozzle through rubbing them with a finger. A more technologically advanced version of the anti-calc system (in Laveo products we call it easy-clean) is used in e.g. a shower column CERS and it requires only to perform one movement in order to get rid of limescale – by pressing appropriate button in the rain shower or turning the hand shower disc to initiate the self-cleaning system of micro-needles pulling out of it.
