Whirlpool and Kenmore Reverse Osmosis WSK-1 systems use filters to remove impurities. A replacement kit includes a filter with advanced binding technology. Use it as a pre-filter or post-filter. The coconut shell granulated activated carbon material attracts and traps dirt, chlorine, turbidity and other particulates. Its high absorption rate improves the filter's performance. While filtering up to 3,000 gallons of water, the system dispenses water at a flow rate of half a gallon per minute. Replace it once every six months for pure water and more efficient system operation.
