How do these price against the 3M carts? I assume based on looks alone they make stuff that's 3M compatible or would I need to swap out the filter head if I wanted to use one of these instead?
3M ScaleGard Pro P124BN-E Water Filter Cartridge are £98 on Amazon.
Water filter system now operational!
Everpure Claris cartridge that feeds the 3 way tap and also the coffee machine direct.
Thanks @StevePeel for the recommendation
