The SureAquaStraw+ consists of two parts - a hard outer casing together with an inner, hollow fibre filter membrane.

The filter is made of multiple hollow fibre membranes, 60 plus metres, packed into a casing. These membranes are produced by a melt spun and drawn processes from 100% polyethersulfone raw materials. After the membrane is manufactured the surface is coated with hydrophilic polymer to aid the filtration process. Filter membranes have a pore size of 0.01 micron.
