2. PHILOSEP DMC is a cartridge with hollow fiber membranes. Polyethersulfone (PES) is the material of hollow fiber membranes having 0.1 μm pore size. PHILOSEP DMC provides safe drinking water with the hollow fiber membranes removing turbidity, bacteria, viruses, and other particles contained in raw water sources. It is a point-of-use (POU) and no energy-cost water treatment device with a gravity filter, which is designed to treat raw water resources such as rivers or lakes for drinking on the spot. It is also easy for anyone and everyone to use at home or outside. About DMC Advantages of DMC Portable and POU (Point of Use) water treatment device Convenient water filtering without pumping thanks to a gravity filter Outstanding water quality without turbidity Reducing water-borne diseases without the use of any chemicals High reliability and durability without not showing the membrane cutting Great for water filter capacity Membrane Structure A asymmetric and sponge-like section structure of membrane The pore size of PES hollow fiber : 0.1 μm
