4 Pack Filters

4 Pack This replacement filter pack is for all 10' standard size residential five stage R.O. systems. 1) sediment, 2) carbon blocks and a final taste and odor reduction filter.  *Upgrading to a Catalytic Carbon stage removes on average 5 times more Chloramines than any carbon block on the market (including the ones specifically designed to "bust" chloramines). The option above adds Catalytic Carbon cartridge in place of 5 micron carbon block. This filter pack is for our WaterCop and Extra Duty (ED) Watercop systems. The filter pack is good for 3,000 total gallons or about 750 pure RO water gallons. You would want to change these filters at least once per year, they provide about 2 gallons a day. If you use about 4 gallons per day, you would change them every 6 months. Please let us know if you have any questions!
