      Small Size Means Flexible Install

      Don't sacrifice precious garage space. The whole house filters from Cascadian are much smaller, and take up no floor space.

      Where does ICS 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.

      It's important to note that products featuring PolyHalt® - identifiable by a 'P' in the part number - may be damaged by contaminants such as hydrogen sulfide or tannins. To ensure optimal performance of PolyHalt®, these contaminants must be adequately removed from the water.

      Our ICS-H product offers a suitable option for pretreatment for hydrogen sulfide. Utilizing ICS-H will aid in eliminating these harmful substances, thereby preserving the efficiency and extending the lifespan of your PolyHalt® products. Always remember to pre-treat your water with ICS-H when necessary to ensure the best performance and durability of your PolyHalt® system.

      Customer service?

      Had questions when I received filter. Left a message on their customer service number and more than a week later, I have not received a response

      Hi Jeanette, I sincerely apologize no one responded to your message. Thank you for letting me know about your poor experience. This is not how we behave and are looking into reasons it happened so we might improve our customer service. Please let me know if there is anything further we can help with. Gabe - Founder of Cascadian Water.

      It works!

      A few years ago I switched from a water softening system to NUVO, but found that the NUVO did very little because I live in an area where I have a well. The company that services my well suggested I purchase Cascadian. The difference is amazing. The mineral buildup with which I was dealing on my faucets and shower heads has almost completely disappeared, and the water tastes just fine. So, no 50 pound bags of potassium or sodium, and no NUVO filters that were a waste of money. I'm obviously a fan of Cascadian.

      Hi Jospeh, Thank you soooo much for sharing your experience after switching from NUVO to Cascadian. Your review helps others learn from your experience and we love it!

      Makes Life Easier

      The Cascading Filter ICS-SP1222K is easy to install and does an excellent job of taking sediments out of the water - use a well and the filter prevents sediments from clogging shower nozzle. Highly recommend and a good value.

      Hi Ralph, Thank you for the great review.
