Master Clear Powder Filter Cleaner is a powder filter cleaner concentrate for cleaning your filters from the inside out!  Just add 4 gallons of warm water to the Powder Filter Cleaner, then let your filters soak.  Very important – DO NOT ADD YOUR ECO-PUR MINERAL FILTER CARTRIDGES TO THE FILTER CLEANER SOLUTION – as this can inactive the minerals in the Eco-Pur Mineral Filters!!  One added feature with the Master Clear Powder Filter Cleaner is that the water will change colors from red to yellow as the filters are soaking – so that you know that the filters are clean.
