<p>A drinking water filter applies a catalytic-magnetic treatment to water. The filter has a pre-filter (1) with a sieve (3) holding a charge of special granules (10). The granules are cleaned at intervals within the rotating sieve section (8) by brushes (9). The sieve section (8) is secured top (12) and bottom (6) with seals. The brushes are operated either by a hand wheel or a clock-triggered electric motor.</p> |
