Maunawai Ceramic pre-filter

Ceramic pre-filter

The ceramic filter is NSF* certified. The flat shape of this ceramic pre-filter for the source optimises both the water pressure and the better utilisation of the surface area, thereby increasing the filter quality.
A special firing technique increases the number of pores and reduces their diameter. This provides effective protection against bacteria, dust, rust, colour, oils, microplastics and other suspended particles.
With a ceramic filter pore thickness of 0.18 µm (0.00018 mm), the tap water runs "drop by drop" through the downstream, multi-stage filter cartridge of the Maunawai source. The 6 additional filter segments require a certain throughput time for the excellent filter result, all based on the natural principle of gravity.

A good filling level in the upper filling container is also decisive for the throughput time. Note the upper fill level so that there is always enough water in the lower dispensing container. The "Refresh" replacement package available from us also includes a ceramic filter. If the water is particularly calcareous and contains a lot of suspended particles, the ceramic filter may need to be replaced before the usual replacement interval of 10-12 months because it has become clogged.

Replacement interval: at least once a year, or after 6 months if the water is very hard and/or dirty.

Cleaning: You can wipe the ceramic well from the outside to remove dirt and deposits. Preferably use a copper cloth with an eco-cleaner or a clean sponge and a little vinegar and water (approx. 250 ml water + 1 tablespoon of vinegar essence).

Preparation: Soak the ceramic filter in tap water. Cover it completely with water. The filter screw should be pointing upwards so that the air can escape from the inside. It is best to leave the filter in the water overnight.
