The better the quality of the water, the purer and less adulterated the aroma. CLEARYL reliably filters the water to leave the optimum ingredient for perfect coffee: pure water for pure enjoyment. The new protective formula was developed especially with modern automatic machines with a One-Touch Cappuccino function in mind. It contains a mineral which stabilizes the calcium carbonate. It is then deposited into the fluid system, even with frequent steam preparation, actively preventing the pipes from becoming blocked. As well as preventing scale, it also filters many other substances detrimental to flavor and aroma out of the water. But the minerals and fluorides that are important for health are retained.
