iSpringFA15 Alkaline Inline Water Filter Cartridge, 10” x 2” with 1/4” Quick Connect, NSF Certified, Add-on for RO Systems, Balances pH & Restores Minerals, 3-Layer Replacement Filter

where I live the water taste like sulfur and I won't drink it and I didn't want to keep buying bottles of water . so I got this ro unit and the water is fantastic ! I had an issue where my UV staying on and I called support and got a man named nick. he knew exactly what was going on and is sending out a replacement part. RO unit is great and service is also great.

I've had an iSpring RCC7 since 2018 and it's been great. However, some of the older alkaline filters I received have had leaky seals, but their customer service is consistently fantastic and Sean helped me get replacements for the leaky alkaline filters. Their phone lines are only open during normal US-East business hours but that's because you talk to actual people based here in the US and they're very understanding. Would buy again!

The ispring water filtration system is awesome! We ordered a spare set of filters to have on hand.A big thanks to John B. and Nick in tech support for all their help.Jerry

We’ve had the iSpring under the sink 5 stage system for three years. It’s been a great addition for better health. I ordered this filter for the annual replacement. The new unit leaked from the easy connector. I called costumer support at iSpring and talked to Michele. She suggested it could be due to a damaged o-ring. She ordered and shipped a replacement for me at no additional cost. Customer support is outstanding. I highly recommend iSpring systems.

Two of these (instead of one) should be included in the "1 year" filter replacement kits which contain 2 of all the other filters (except the RO unit). This has been quite bit of annoyance since I change all 5 filters (stage 1, 2, 3, 5, 6) on minimally used once a year and the RO unit (stage 4 I believe) every two years. So this causes me to buy one of these every two years (along with the RO filter).The unit arrived well packed was all sealed up and included a parts kit.I have to knock off a star for the annoyance of iSpring not including 2 of these instead of 1 in their water filter replacement kits.

We have a well and I use this on my reverse for our drinking water. It’s better than bottled water.

Michele was very helpful and efficient. There was one defective filter and Michele is making sure it was replaced . Very much appreciated. Great customer service.

Very easy to install and great price. Definitely recommend the system and great warranty with the rep Michele.
