Abstract

A filter (10) is disclosed which comprises a casing (18) having an inlet (42) for water to be purified. There is a first stage filter (12, 16, 58) for removing solids from the water. The water flows from the first stage filter to a second stage filter (66) for the purpose of subjecting the water to ultra filtration or micro filtration and/or to reverse osmosis.
