Devon came to our house to review our system and was able to identify a new filter that would help with hardness of water. The water is indeed softer less water spots in the stainless sinks. I’m extremely happy with the results and Cascadian Water!
Thank you so much for the fantastic review! We're thrilled that Devin was able to assess your system, recommend the ICS-SIK filter, and make a real difference in your water quality. It's great to hear you're experiencing softer water and fewer water spots on your stainless steel sinks – that's exactly the kind of result we love to see.
Your satisfaction is our top priority, and we're so glad you're happy with both the results and your experience with Cascadian Water. We appreciate your business and are always here if you need anything in the future.
Cheers to enjoying your softer water!
Our Cascadian Water filter (ICS-SIK) for the (ICS-SI) filtration system has been preserving water for us for the past two years. It is amazing how clear the water is all of the time; when we change out the new white pristine filter with the brown-stained pre-filter each year, we appreciate this hard-working system and don't need to think about it at all.
Thank you for sharing your positive experience with the ICS-SIK filter and ICS-SI system! We're thrilled to hear that it's been consistently delivering clear, clean water to your home for two years.
The contrast between the new and used filters is a powerful visual reminder of how hard the system works to protect your water quality. We're so glad you can enjoy the peace of mind that comes with knowing your water is taken care of.
