Review: Excellent product and amazing customer service! - I couldn't be happier with my experience with iSpring Filters. The product itself is excellent -high quality, well-built, and performs exactly as advertised. What really stood out, though, was the customer service. I had an issue with a filter that malfunctioned, and Nick from iSpring went above and beyond to help. He was responsive, professional, and immediately sent replacement filters without any hassle. That level of support is rare these days and truly appreciated. It's clear that iSpring stands behind their products and genuinely cares about their customers. Thanks again to Nick for making the process smooth and stress-free. I highly recommend iSpring Filters to anyone looking for reliable water filtration and top- tier customer service.
Review: Outstanding service and product - I purchased an iSpring wall mounted three stage (canister) whole house water filtration system several years ago to replace a dual tank floor mounted system that took up too much room and did not back flush properly and could not deliver quality water results. The iSpring system takes up very little wall space and maintenance is easy, simply changing the three filters yearly based on our water usage. Customer service was great with Nick giving me sound advice regarding installation. A couple of years later he gave me good advice as to the use a heat gun to loosen tanks when I had overtightened two canisters. I recently learned that Nick is still providing customer service when I had a question regarding an order for replacement filters. We are serviced by a small water utility company which has pure water, but the water has high levels of sand and sometimes high levels of chlorine. The 5-micron sediment filter removes most of the sand and two CTO carbon block filters do a great job removing chlorine and any remaining sand. We do experience water line breakage occasionally which can introduce large amounts of sediment into the lines which is a health hazard and can damage water heaters, dish washers, and washing machines leading to premature failure. This is another reason to install a whole house system instead of point of source filters for sinks and lavatories. I do find the iSpring replacement filters high quality and reasonably priced particularly when purchased in cases of four like my recent order. Merlin

## Features

- Protect Your Family and Household Appliance from Chlorine and More: Say goodbye to smelly, bad tasting water! The FC25B carbon block filter is specially designed to remove up to 99% of chlorine from water as well as various natural organic compounds, taste and odor compounds, and synthetic organic chemicals.
- Standard Size: Our filter set fits standard 20” x 4.5” housings,
- Top-Notch Quality: Our FC25B CTO Carbon Block filters are made of high-quality coconut shell activated carbon for maximum filtration efficiency and filter life. Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants may adsorb. They are tested by an independent third-party to meet NSF/ANSI standards. The 20” x 4.5” filter cartridges have a minimum impact on water flow (up to 15 GPM) and require minimum maintenance
- Peace of Mind Customer Service: Register online to activate your manufacturer warranty and life-time free tech support from U.S. local support team. We stand behind our products and if you encounter any problems with any of our products please reach out to us immediately. We are happy to help!
- Please Note: The cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use. Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.

### ⭐⭐⭐⭐⭐ Great Customer Service
*by S***R on April 7, 2025*

iSpring products are terrific and I could not be happier with my water quality. I have had my system running flawlessly since 2017. Recently, I had a problem with a low flow rate on a newly installed filter. I contacted iSpring customer service and communicated with Julius. What a pleasure to receive such a prompt and courteous response. He understood the problem and arranged to ship a replacement. They have great products and it’s reassuring to know that they stand behind them.
