The EcoWater Reverse Osmosis Prefilter (7208683) is a compatible replacement prefilter cartridge for use with the EcoWater ERO-335 Reverse Osmosis System.
This EcoWater compatible pre-filter replacement reduces sediment, dirt, sand, and other particulate matter down to the 5 micron level; it also utilizes carbon to reduce the bad taste and odor of chlorine. The EcoWater pre filter is instrumental in the EcoWater ERO-335 RO system because it protects the EcoWater RO Membrane (7208706) from being corroded by chlorine. It also prevents sediment from clogging the RO membrane, which extends its life. The pre filter should be replaced more often if it becomes clogged by sediments and if you notice a decrease in water flow because high levels of sediment will reduce the capacity of this EcoWater compatible prefilter.
