## Long description

Aquaphor Extra Soft K5/K7 is a water softening filter cartridge designed for household use where reduction of water hardness is required. Compatible with K5 and K7 housings, this cartridge contains ion‑exchange media that lowers concentrations of calcium and magnesium in water while maintaining a flow rate of up to 100 l/h. The cartridge is intended for treatment of drinking and utility water to decrease scale formation in appliances, fixtures and plumbing.
Advantages
The cartridge lowers hardness ions through ion‑exchange without substantially altering water taste or odor. Its design is compatible with standard K5 and K7 housings, enabling straightforward installation and replacement. With a rated flow of up to 100 l/h, the filter supports continuous household use for sinks or point‑of‑use installations. By reducing scale buildup, it helps extend the service life of kettles, boilers, water heaters and other appliances that contact hard water.

How to use
Install the Aquaphor Extra Soft cartridge into a compatible K5 or K7 housing following the housing manufacturer's instructions. Before installation, shut off the incoming water supply and relieve pressure in the system. Insert the cartridge, ensure proper sealing and reassemble the housing. After installation, open the water supply and allow water to run for a short period to remove trapped air and to condition the cartridge media. Replace the cartridge according to usage, local water hardness, and the manufacturer's recommended interval for effective softening.
Usage recommendations
For best results, use this cartridge with regular maintenance of the K5/K7 housing and pre‑filtration where water contains sediment. Monitor appliance performance and visible scale formation to determine replacement frequency.
