Filter Assist is designed to increase filter efficiency of sand filters. Filter Assist works by penetrating the sand with a highly effective polymer formula collecting microscopic particles that would otherwise pass through the sand media. Filter Assist restores water sparkle after heavy bather loads or heavy rains. It is also recommended to be used as part of routine pool water treatment. Regular use of Filter Assist will make your sanitization program more efficient by reducing stress on your sanitizer.
