Duration: up to 1500 gallons (5500 litres) of water Installation Style: Above the counter Ideal to use as a single stage water filtration or as a pre-filtration for ionizers, the Ultra-E Sub-micron Depth Filtration Series is manufactured using a proprietary, patented, electro-absorptive media technology, and is capable of removing sub-micron pathogens and inorganic contaminants through electro-adhesion and ion exchange. This technology makes it possible for a non-woven media to product filtration efficiency comparable to ultra-membrane filtration but at very low pressure drop, with high flow rates and high loading capacity working equally well in fresh, brackish or salt waters. The media in the Ultra-E filter is NSF 61-approved. The ULTRA-E filter reduces, or removes the following pathogens:>99.99% of viruses (pollo, rotavirus, norovirus, etc.)**>99.99% of bacteria ( e coli, legionella, pseudomonas, etc.)**>99.95% of cysts (giardia, cryptosporidium, etc.)**** Tested by a certified laboratory in the U.S. (testing was done at 6.5pH) The Ultra-E filter removes or reduces the following heavy metals:>95% Lead **>90% Ferrous Iron **>95% Arsenic V **>95% Cadmium **>85% Chromium **>75% Selenium **>60% Mercury** Tested by a certified laboratory in the U.S. (testing was done at 6.5pH) The ULTRA-E filter also removes, or reduces the following organic and inorganic chemicals:VOCs (volatile organic compounds)PCBs and BPAResidual pharmaceuticalsBio-fouling precursors: organic acids, proteins, polysaccharides Kit Includes: Single stage white housing Ultra-E Premium cartridge 3/8" White Tubing Design & Made in USA Note: Does not work with Super 501.Not recommended for SD501U as set up is not easy.
