You can replace filters and membranes in seconds with theÂ GE Twist & Lock design. Just twist the filter a quarter turn and it locks into place. No tools are needed and thereâ€™s no mess. Look for the Twist & Lock logo on GE packaging.
GE’s hydrophilic membranes for filtration include: polycarbonate and polyester, nylon, nitrocellulose-mixed esters, polyethersulfone, cellulose acetate and silver membranes
Filters for prefiltration or high dirt-loading capacity include: glass fiber with or without binding, and polypropylene prefilters, which are often used for removing large particulates from solutions before utilizing the smaller pore-sized membranes
Hydrophobic membranes include: TeflonÂ® with or without a supportive backing; and nylon, with an internally supported web and polypropylene membranes. PVP-free PCTE (polycarbonate) from GE, which is slightly hydrophobic, is included under the hydrophilic membranes
