If you require a replacement cartridge that we don’t stock, please call in at the shop. Or alternatively phone or email us with the make and model of your filter. We should be able to order one in at a competitive price.

Cartridges that fit into standard kitchen type housings generally come in two sizes.
“9 inch” which is actually 8 3/4″ or 220 mm OR
“10 inch” which is actually 9 3/4″ or 245 mm.
All filters are rated on a nominal scale which, on a good quality filter, means the pore size can be up to 4 times larger than the real “absolute” rated size. On cheap imported filters, the real pore size can be anything up to 100 times larger.

Don’t be fooled into buying a filter because of its advertised micron rating unless it has available a certified absolute rating.
