I have been using the iSpring Whole House Filter set for many years. I recently ordered another set. This company has fantastic customer service. After installing a new filter set I encountered a low pressure problem on the filtered side, the pressure was normal on the unfiltered side. I'll double check that I installed the filters in the correct order. I wrote to iSping support about the problem. The very next day, Nick contacted me and said that iSpring would send me a new set of filters as soon as possible. A few years ago I used iSpring Customer Service to resolve an issue with an iSpring reverse osmosis system. Received the same excellent customer service. I really like that this company stands behind their products. Nowadays it is rare to find a company that offers such a good service to its customers. I will remain a regular customer knowing that they will always support me!
