● High filtration rate
Membrane-Clean WF-I uses PTFE membrane of uniform pore size and the effective filtration area of 10 inch filter reaches 0.93 square meters.  The composition of doubled feature provides filter with high filtration efficiency, high flow rate and long life.
● Performance Consistency
The filtration medium and Attachments of Membrane-Clean WF-I PTFE cartridges manufactured in clean-room are strictly controlled and processed in raw material. The high cleanness filter separating out extremely low organics experienced ultra-pure water wash and 100% integrity test which ensures the consistency of performance.
