PWK30 filter

This Proline filter can replace the Watkins Tri-X ceramic filter cartridge. It is also available in boxes of 5.

Also available is the Claralys version of this filter, made in France, whose honeycomb-textured fabric won't fray with use and captures more impurities than generic filters, so you can be sure of the best possible filtration.
