Why Replace Your Filters?

To keep your ICS-STP performing at its best and ensure you continue to enjoy purified, naturally softened water, regular filter changes are essential. Here's why:

  • Maintain Water Quality: Over time, your filters remove sediment, chlorine, and other impurities from your water. Replacing them ensures continued clean, clear, fresh-tasting water
  • Maximize Efficiency: Clogged filters restrict water flow, reducing your system's efficiency and potentially leading to low water pressure
  • Enjoy Continued Benefits: The PolyHalt® media in your filter gradually depletes as it softens your water. Replacing your filters ensures ongoing soft water benefits, including softer skin and hair, and protection for your appliances
  • Peace of Mind: Know that you, your family and home are always enjoying the healthiest water possible

Environmental Responsibility

  • Sustainable Choice: Reduce waste and minimize your environmental impact. Save 1,000s of gallons of water each year. Keep salt where it belongs and not polluting our water supply
  • Fewer Materials: With Cascadian's exclusive PolyCor™ technology you get more treatment with less. One less housing and one less filter means less materials needed to get full treatment

    Frequently Asked Questions

    Where does the ICS system go in my home?

    Where it can fit, and where it can easily get access to your home's water source. This is typically a garage, crawlspace, or even a closet.

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

    How often do I replace the filters?

    Most people replace their filters once per year, or sooner if they start seeing issues with their water again. Learn about water issues here

    Good Filters

    These filters work good but do not last long our water as a lot of iron in it and I have to change them about every six months. This get very expensive at almost $500 each time

    Hi Charlotte, Thank you for your review and for sharing your experience with the ICS-STPK. We understand your concern about the filter lifespan and the cost of replacements. While the ICS-STPK is effective for low to moderate iron levels, it sounds like you may have a higher concentration that requires a more specialized solution.

    For heavy iron removal, we highly recommend our ICS-SIP system. It's specifically designed to tackle challenging iron levels and can significantly extend the time between filter changes, saving you money in the long run.

    We'll call to discuss your specific water conditions and help you determine if the ICS-SIP is the right fit for your needs. Please feel free to contact our customer support team for personalized assistance. We appreciate your feedback and are committed to helping you find the best solution for your water!
