This HydroLogic® Membrane Element reduces 98% of total dissolved solids. For all membranes, RO output depends on the source water temperature. At 77 degrees, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output. Replace membranes when product water decreases and/or ppm increase. Replace when product water decreases and/or ppm's increase. Let water run for one hour before use.
