Ecosoft Scalex replacement cartridge for protecting appliances from limescale
The limescale filter cartridge FOSE200 is a replacement cartridge for the Ecosoft Scalex FOSE200 filter. It reduces limescale build-up in boilers, instantaneous water heaters, heating taps and other appliances exposed to hard water. It contains an active anti-limescale agent that, according to the manufacturer, reduces calcium and magnesium deposits on internal surfaces.
It is suitable for home and professional use.
How does it work and where to install it
Insert the cartridge into the FOSE200 filter before the appliance you want to protect. The active agent in it prevents calcium and magnesium from building up on heating elements and internal surfaces, which can reduce efficiency and shorten the life of the appliance.
You will find the complete filter with housing on the page for the limescale filter for boilers, instantaneous water heaters and heating taps FOSE200. For a washing machine there is the smaller FOSE100 filter with the FOSE100 replacement media.
Who is it for
Choose it if you already have an Ecosoft Scalex FOSE200 filter and need a new cartridge, or if you want to protect heating appliances from limescale. The cartridge is designed for protection against limescale, does not soften water completely and does not remove chlorine or other substances.
When to replace it
The manufacturer recommends replacing the cartridge every 6 months or after 20,000 litres, whichever comes first. Regular replacement is important, because a used-up cartridge no longer protects against limescale.
