    Why Replace Your Filters?

    To keep your ICS-SP 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

    • Sustainable Choice: Reduce waste and minimize your environmental impact. Save 1,000s of gallons of water each year and 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. If you have questions a plumber would be able to help you find the best spot. 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

      What is the return policy?

      If you are unsatisfied within 60 days of purchase, return the housing and we'll refund your purchase no questions asked.

      How fast do you ship?

      We typically ship same business day if the order is placed before 2 pm PST using UPS ground.

      Satisfied with Filtration, Concerned about Price

      The filter system seems to work pretty well, although it seems I still have harder water than I expected. But the filters have gotten very expensive. This is my main complaint.
