Polypropylene

Polypropylene water filters are made from a material that is extremely durable and lightweight, effectively filtering larger impurities such as dirt, sand, and rust from the water. It is often used as the first stage of filtration in water treatment systems to protect more sensitive filters from larger particles.

Micron: A unit of measurement for the filtration of water filter cartridges, equal to one millionth of a meter (1 μm = 1/1000 mm). The lower the micron value, the better and more effective the filtration.
