Fisher and Paykel fridges often use the 836848 which is an externally fitting twist and lock cartridge. It can be difficult to source, moreover, its usually pretty expensive in the UK. Whilst we cannot offer a cartridge which fits the existing filter-head, we can offer an inline filter which will offer broadly similar performance which retrofits very easily - Simply disconnect the tubes from either side of the existing filter head and connect them to either end of the supplied filter. We have hundreds of customers using this as a replacement for their Fisher and Paykel and generally we get very few issues - and we are always here on the phone should you have queries during installation.
Cartridge life: 6 Months
