Review on 🚰 iSpring 7PK GAC 5-Stage Replacement Filtration System by Walter Harmon

You simply can't go wrong with iSpring. I've bought two R/O units and dozens of filters from them and while their prices are amazing, their service is top notch - true old fashioned US English customer service that really engages the customer. , is always right. I contacted them several times to buy spare parts and they sent the parts for free! If I have a question, they know exactly what I'm talking about and always give the right answer. On the first call. Without delaying me. We have our second machine in 20 years, the newest was installed in 2013, and the water quality is so good I can't drink anything else, not even premium bottled water. Ease of installation. Great prices. great service I highly recommend.
