Ultrafiltration (UF) Water Filter Membrane
5 |
Description
Ultrafiltration (UF) is an important purification technology used for the production of high-purity water. UF is effective for the removal of colloids, proteins, bacteria, viruses, parasites protozoa, and pyrogens, (e.g., gram-negative bacterial endotoxins), and other organic molecules larger than 0.01 Micron size and most other water contaminations known today. Also removes pesticides and herbicides, as well as the hardness in water and some salt.

Great Filter
I found this filter as a replacement for a similar filter made by Filtrex, which is nearly impossible to find now. It was a perfect replacement and is working very well in my RO system. Crystal Quest is the only other manufacturer that I have found that makes a cartridge in this size that is able to filter below 0.2 microns.
