Limescale build-up from hard water is the leading cause of poor performance and eventual failure in coffee machines. This genuine Gaggia Intenza filter cartridge is designed to actively filter the water, significantly reducing mineral content before it enters the boiler. By consistently using this original filter, you protect the internal components, reduce the frequency of manual descaling required, and ensure the water used for brewing is clean and pure, resulting in a noticeably better-tasting cup of coffee.
