Siliphos Retainer Clips

Twin pack of plastic retainer clips that we use in our standard carbon block cartridges to keep the polyphosphate crystals in place.

Polyphosphate crystals are used to reduce limescale in medium hard water areas. 

Take a look at our hard water filters for drinking water or hard water filters for mains water. and if you have any questions about how to reduce limescale in your water please call us on 01352 838 281.

Easy to fit as they just push in, although be careful not to catch your finger underneath them as they can nip. 

Free UK standard P&P on plastic clips.
