I rely on my filters.

Every nine months I replace my filters to remove the iron out of my well water. What a difference it makes. Thank you, CASCADIAN for your quality products.

Thank you Carolyn for sharing your personal experience with your ICS-SIK. Sharing your experience will help others who are considering a Cascadian water treatment system of their own.
