Undersink Triple Ultrafiltration Water Purification System with 8 stages that uses a UF membrane to remove bacteria and biological pathogens for areas such as well water. 3 cartridges that also feature a solid carbon cartridge, and our top of the line 6-stage cartridge containing the Coconut Shell Carbon(GAC) and KDF resin layers.

UF utilizes a semi permeable membrane - a thin layer of material capable of separating substances when a driving force is applied across the membrane. It is a pressure-driven barrier to suspend solids, bacteria, viruses, endotoxins and other pathogens producing water with very high purity and low silt density. Solid carbon cartridge is for removing Volatile Organic Compounds (VOC's), insecticides, pesticides and industrial solvents. The added combination of Coconut Shell Carbon or Granulated Activated Carbon(GAC) and Eagle Redox Alloy media increases the systems' effectivity in removing hundreds of other contaminants from your tap water. This system is mainly designed for use with private wells but is also usable for tap or municipally treated water. Undersink water filter systems do not add clutter to your kitchen as it works behind visibility. This compact, triple cartridge system is your best option to get reverse osmosis quality water without the tank and without any waste water.

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 .01 Micron size and most other water contaminations known today.

1. Donna on 4/26/2011, said: 11111

This is a very effective water filter. I'm at the end of the line in the Colorado River water shed. The water from the tap just awful. This hard working compact filter does an amazing job. The rate of filtration and quality of the water outstanding. I did not have a copper line to quick tap in to so installation was costly. The paperwork with the filter said it had to be installed by a professional licensed plumber to be under warranty. The bill for installation was $237 Ouch. Customer service at is excellent. There are real people there who care. I highly recommend this filter and company. DL Santa Barbara CA
