A water purification unit particularly adapted for household use, and for operation at high pressures, including two main co-operating parts forming a chamber, with a seal positioned between such parts, and a cap compressing the seal and holding the two parts together. The interior of the chamber can contain one or more filtering elements such as a particulate matter filter, a carbon filter or a reverse osmosis filter. To withstand high internal pressures without leakage or damage, mechanical connections are provided within the chamber to form a further positive connection between the two main parts forming the chamber, so as to maintain such filter elements in position within the chamber. A water purification system particularly suitable for household use is provided, incorporating the above unit, wherein tap water is fed to the unit and purified outlet product water is discharged and introduced drop by drop into an open container, affording an aerated storage reservoir of purified water ready for use, and including water overflow means from such container to an outlet drain, the waste water from the water purification unit being also discharged to such drain.
