      Why Replace Your Filters?

      To keep your ICS-TP 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 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.

      This works even with San Diego hard water

      We have been using Cascadian water filters now for about 2+ years and really like it. Our shower heads no longer show all the mineral deposits on them. Water tastes better and everything works great now. Changing the filter is very easy to do even if you are 81 years old. Great company and products.

      Great water treatment system.

      I was a converted "Citrus based" water treatment system to Cascadian system and I'm delighted that I did. I was always leary of the bluish water dispensing out from my old citrus based system. Perhaps the acidity is just too much and etched on the inside of my copper pipes. resulting in discolored water. Now changing to this system, I'm more than happy with the water quality and without having to worry abiout the long-term effect of drinking bluish water.

      Thank you for your positive review and for choosing our ICS-TPK Replacement Water Filter for your water treatment needs. We are thrilled to hear that you have noticed a significant improvement in your water quality since switching from a citrus-based system to our Cascadian system. Your experience clearly demonstrates a major difference between Cascadian's PolyHalt and our competitors' citrus treatment for hard water. Thank you for trusting us to provide you with clean and safe water. We appreciate your business and look forward to serving you in the future.

      Good water treatment system

      We are satisfied with our filter. Good tasting water. No calcification on the water fixtures. I like the updated installation instructions. We've had the system for 7 years. Easy to install for this 65 y.o.

      Great water filter for hard California water

      My daughter recommended the Cascadian water filter and after reviewing the other systems on the market and available around San Diego I concluded the Cascadian water filter was the best for me. Our water is extremely hard down here and now the water in my home is perfect and soft!! We can easily tell the difference, in the taste, after washing our hair, etc. The system was easy to install (I did have help from a friend/plumber) and once it's turned on you just walk away and forget about it until next year when the filter needs to be replaced. No noise, no electricity needed, easy to maintain and service. This is a great system for my home. Highly recommended.

      We're so happy to hear that your daughter recommended Cascadian Water and that you're thrilled with the results of your ICS-TP system! It's fantastic that you're experiencing the difference in your water, from the taste to the feel after showering. It sounds like the ICS-TP is living up to its promise of providing 'perfect and soft' water in your home, even with the challenges of hard water in the San Diego area.

      We appreciate you highlighting the easy installation and maintenance, as well as the lack of noise and electricity needs. Those are key features we strive for in all our systems, making them a convenient and hassle-free way to improve your water quality. It's wonderful that you were able to install it with the help of a friend, demonstrating that you don't need to be a professional plumber to get the system up and running.

      The ICS-TP is designed to be a 'set it and forget it' solution, quietly working in the background to provide you with clean, soft water for all your household needs. No more worrying about hard water stains, dry skin, or unpleasant tastes – just pure, refreshing water throughout your home.

      Thank you for the glowing review and for choosing Cascadian Water! We're confident you'll continue to enjoy perfect, soft water for years to come.

      Excellent Product

      Easy to install, high quality product. I noticed a difference in my water immediately with better taste and no smell. My skin is less dry as well. Highly recommend!!

      Hi Bobbi, Thank you so much for sharing your experience with everyone interested in learning about customer experiences with Cascadian. Also thank you for the wonderful picture. Your installation looks very professional and is plumbed exactly as recommended.

      “I figured it was time to change my filter when I began to smell a little bit of chlorine. I also discovered that when the Cascadian filter is functioning normally you need to clean the toilet more often because the filter removes the chlorine, that’s my personal barometer. “

      “The shower, dishes, the stuff that’s noticeable – the filter makes my life much easier. Dishes are cleaner, shower doors are easier to keep clean, I’ve always squeegeed the shower everyday but that task is much easier with the Cascadian in place.”

      “It might have been 18 months and I’m a family of 4 so I’m sure I got the full use out of that cartridge. We drank that water and cooked with it for 27 plus years prior to the filter and that’s scary.”

      Is this Normal?” 

      Todd sent this picture because he was concerned something might be wrong. Both these filters are ICS-TPKs but the one on the left is about 18 months old and the one on the right is brand new. Todd’s water supply comes from the City of Mesa, AZ. where hardness ranges from 12 – 22 grains per gallon. The city does not list other common water elements such as iron. Click / Press here to see the city’s full reports. Todd has a household of 4.

      Happy with our water

      The filter from Cascadian is living up to its advertising! We have been concerned about what the city is putting into our water and had been searching for some way to improve our water, soften it and keep the wanted minerals. This filter makes us very happy that we don’t have to buy bottled water anymore! The plumbers connected with Cascadian were truly amazing!

      Hi Kevin, we're thrilled to hear you're happy with your water! Thanks for sharing your experience and for trusting Cascadian Water. We're glad our team could help. Enjoy your refreshed water!
