We have had an iSpring system for 5 years and it does a great job of filtering our water. It removes the minerals that would leave rust spots in our sinks protecting our fixtures. We recently purchased replacement filters, but one set was faulty and restricted our water flow to almost no flow. This had never happened in the years we’ve had the system and replaced the filters. A quick call to customer service and iSpring said they’d replace the filters. Thanks Nick! Update: The filters that arrived initially were the wrong size. One email to Nick and he resolved the issue. The correct size filters arrived quickly and our system is working perfectly! Nick has been great to work with and we remain happy with iSpring.

We’ve been using iSpring filters in our house for close to a decade. They’ve eliminated our well water concerns. We recently received a filter that had an abnormal pressure drop. After calling iSpring, we got a hold of nick who was very receptive to our feedback. He quickly sent out replacements and even advised us on our current setup. ISpring is very responsive and stands by their commitment to customer support.
