High Quality Stainless Steel Filters Fitted With Genuine Doulton® Cleanable Ceramic Cartridges For Economical Absolute Sub-Micron Filtration - A Practical Alternative to Costly Throw-Away membranes!

The Doulton ceramic cartridge membrane offers both; absolute dead-end filtration and depth filtration. Far more economical absolute micro-filtration than any 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>>

The 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, Sterasyl® have pure silver through-out the ceramic shell preventing bacterial growth.
