Waterdrop - TSPP Under Sink Sediment Water Filter, Replacement TSU-W system - White

Compatible with most RO and under-sink filtration systems using 1/4-inch or 3/8-inch quick-connect tubing, it can also connect to refrigerators and RO water purifiers. The tool-free filter lasts up to 1,100 gallons or 9–12 months; replacement after 9 months is recommended for consistent performance. Do not connect it to a hot-water line.
