Environmentally sound production
Unlike rolled membranes, such as ones used in reverse-osmosis devices, hollow-fiber membranes are made out of pure polyethylene without the use of solvents.

Made of pure polyethylene – one of the most inert materials known – hollow-fiber membranes have a long service life and can hold up well under unfavorable conditions.
A huge filtering surface in a small volume of space
The effective surface area of the membrane used in Sawyer filters is 7,500 cm2 – over 8 sq. ft.
Large absorbent capacity
A hollow-fiber membrane is capable of filtering a considerably larger amount of “dirt” (large-particle impurities) than bulk filters such as polypropylene cartridges or carbon blocks.
