Product Description

Changing filters is exceedingly simple thanks to John Guest push-fit fittings supplied with the original Water Gem system (see installation instructions). Cartridges can also be retro-fitted to existing under-sink systems, including those utilising 3-way taps.

Buying genuine replacement filters guarantees the same great tasting water as when the Water Gem system was first installed.

Filters have a lifetime of up to 6 months / 2,500 litres, which ever comes first.
