A highly effective drinking water filter cartridge that combines dual layered sediment filtration, activated carbon, KDF media, and calcite. Official replacement filter cartridge for iSpring countertop drinking water dispenser CT10, which delivers the best drinking water possible from a single convenient cartridge.

Please note: This countertop water filtration system DOES NOT lower TDS value, instead it will keep healthy minerals in your water. If you are interested in a filter that eliminates TDS, please consider our iSpring tankless under sink Reverse Osmosis (RO) system RO500 or countertop RO water filter system RCT600 for more details.

Installation Step 1

Remove the aerator if the faucet has one, and determine if your faucet has inner threads or outer threads.

Installation Step 2

For faucets with internal threads, use the metal adapter and 2 sealing washers to connect the diverter valve to the faucet. For faucets with external threads, place the sealing washer into the diverter valve of the filter and connect to the faucet.

Installation Step 3

Turn the diverter handle in line with the connector for regular tap water. Turn the diverter handle perpendicular to the connector for filtered water.

Installation Step 4

To flush out the loose carbon, keep the faucet on for a couple of minutes until the filtered water runs clear.
