Doulton Ceramic Filter Elements

All Doulton ceramic cartridges are bacteriostatic - that is, self sterilizing for bacteriological safe cleaning and handling.

This cartridge combination provides: 100% rejection of cysts and >99.99% of pathogenic bacteria such as cholera, typhus, amoebic dysentery, ecoli, colibacillose or bilharzia among others. Depth filtration of particulates >0.2 µm (dirt, turbidity etc).

In addition, a variety of dedicated fittings are placed inside the bore of the element to remove chlorine, bad taste and odor, pesticides, herbicides, industrial solvents and heavy metals.

The ceramic cartridge membrane offers both; absolute dead-end filtration and depth filtration. Far more economical absolute micro-filtration than any bacteria grow-through prone thin film poly-carbonate, polyester or Teflon® dead-end membrane or throw-away depth filtration membrane made of PVC, PVDF, PTFE, cellulose, nylon, polyethersulfone, polypropylene. For more details on how Doulton's ceramic micro-filtration works>>

Ceramic cartridge is less expensive no matter what you pay for it than any absolute membrane because it can be cleaned and reused over 50 times. Unlike the man-made materials used in dead-end and depth filter membranes, the micro-filter have pure silver through-out the ceramic shell preventing bacterial growth.

Doulton ceramic filter elements utilize the natural properties of high purity specialized diatomaceous earths to provide a range of strictly controlled pore sizes giving maximum filtration efficiency together with high porosity for maximum flow. Doulton ceramic water filter elements can be quickly and easily cleaned many times to prolong their working life.

0.9 micron absolute; 100%
0.5 - 0.8 microns; >99.9%
0.2 - 0.5 microns; >98%
