The Calmag CalFresh C Drinking Water Filter Kit is a complete under-sink water filtration system that delivers clean, filtered drinking and cooking water on demand through a dedicated separate drinking water tap. The kit is supplied complete with the CalFresh filter housing, a 10" Fresh C carbon block cartridge, a dedicated drinking water tap, and all inlet/outlet connectors required for installation β everything needed for a full under-sink filtered water installation in one box.
The Fresh C cartridge uses a fine-grade carbon block with a small-mesh structure to achieve effective chlorine reduction, as well as filtration of sediment, dirt, discolouration, unpleasant taste and smell, organic material, bacteria, cysts and heavy metals. Water from the mains is directed through the cartridge before being delivered to the dedicated drinking tap β producing a continuous supply of filtered water at the touch of the tap. The CalFresh C housing carries a lifetime guarantee when registered. Replacement Fresh C cartridges are sold separately (CART-FRESH-C) and should be replaced every 4β6 months.

Frequently Asked Questions
Can I use the CalFresh C with a water softener already installed?
Yes β and this is a common installation combination. When a water softener is installed, Building Regulations require at least one unsoftened drinking tap. The CalFresh C is typically installed on the unsoftened mains cold tap branch (the same branch that feeds the mandatory drinking tap), providing filtered, unsoftened drinking water at the dedicated drinking tap. The filter cartridge is connected before the drinking tap in the pipe run.
How do I know when to change the cartridge?
Calmag recommend changing the Fresh C cartridge every 4β6 months. The actual lifespan depends on local water quality and volume of water filtered β in areas with high sediment or very chlorinated water, the cartridge may become saturated more quickly. Signs that the cartridge needs replacing include reduced flow rate through the drinking tap, and return of chlorine taste or smell in the filtered water. Register with Calmag to receive free reminder notifications.
Does this kit include a tap?
Yes β the CalFresh C Drinking Water Filter Kit includes a separate drinking water tap for installation into the kitchen sink or worktop in addition to the filter housing and cartridge. This tap is dedicated to the filtered water supply and is installed independently of the main kitchen tap.
β οΈ Note: Replace cartridge every 4β6 months. Replacement cartridge MPN: CART-FRESH-C (sold separately). Housing carries a lifetime guarantee on registration. Connect to unsoftened mains cold supply β not to softened hot or cold supplies. No power or electricity required.
