Great Product and Customer Service. Thanks Nick, I've owned my 7 Stage iSpring filter that has operated for several years and have replaced filters 3 times in the past. i needed new filters and found this 2 year kit. i purchased this kit and called iSpring with questions before installing. I spoke with Nick in the service department. he told me i had bought a kit which has the wrong RO membrane. He is going to send me 2 of the correct RO membranes to complete my kit.

works great
I have used this system for a while now, and it works perfectly. The 7 stage system makes a lot more sense than drinking bottled water that is contaminated with plastic. I would very highly recommend it!
