I purchased the 3-stage whole house filtration system 3 years ago. After the initial installation I searched for less expensive filter cartridges. I was very disappointed in the cheaper versions and have since changed back to the iSpring CTO cartridges. They are constructed much better and last 4 times longer than the cheaper brands I tried. I have learned my lesson. I highly recommend the iSpring CTO cartridges!
