Comments: I purchased this DI Filter to replace my aging one. This fit my RO/DI unit perfectly even though it is not one of the brands listed. My other DI color changed as well, but was a little hard to see. This one is dark like it should be and is easy to see when it is time to change. Works well, TDS back to 0.
