ICS-TPK cartridge filter replacement kit

The ICS-TPK cartridge filter replacement kit is made specifically for the Cascadian ICS-TP system and is engineered to improve taste and odor, reduce VOCs and soften all the water for every use in your whole home or business. It is an excellent choice for city water and can stand alone or be combined with existing treatment for improved performance.

This revolutionary treatment provides two high performance treatments in one filter cartridge;

  • First treatment is a superior activated carbon filter
    • Improves taste and odor by filtering chlorine
    • Reduces VOCs to further improve water safety
  • After carbon treatment the water passes through PolyHalt® media for the second treatment where it is softened without salt and further conditioned to treat silica and blue copper staining which extends the life of plumbing, fixtures, appliances, windows and glassware etc., by protecting them from damage caused by untreated water.

During maintenance you'll need to fit a bucket and have enough space to turn the sump wrench which comes with your system

Kenneth Bell (Ammon, US)
Happy with product and service

My water filter replaced an old water softener that had been disconnected by the previous owner of my home. I live in eastern Idaho where the water is pulled from an aquifer and is mineralized needing filtration. This filter does its job and is easy to change the filter element annually.

Hi Kenneth, Thanks for taking the time to leave a fantastic review! We're so happy to hear our filter is doing a great job handling your mineralized well water in eastern Idaho. Easy annual filter replacements are definitely a plus! If you ever have any questions about your filter or need any assistance in the future, please don't hesitate to reach out.
