We are on a municipal water supply, and the chlorine odor and taste seemed to become much stronger in the past few weeks, so I decided it was time to install an under-counter water filter. The installation process was pretty simple and just about anyone who has installed a faucet should be able to intall this filter if they read and follow the directions. All of the necessary hardware was included, along with more than enough plastic tubing to make the needed connections. Only basic wrenches are needed to tap into the cold water line, like those that you would need to install any water line fitting. The tubing that connects the cold-water supply to the filter, and the filter to the spigot use pex-style fittings. The filter works quickly, filtering enough water for a pot of coffee in a few seconds. These are so much better than pitcher-style filters. The replacement cartridges are also very inexpensive, so I ordered an extra set to have on hand, and set up am Amazon subscription purchase for every 6 months, so when the new filter cartidges arrive I know it is about time to replace them. The difference in the taste and odor of out water was amazing! My wife thought our municipal water tasted ok, but after I installed this filter and she compared the filtered and unfiltered water, she was sure that I did something to the unfiltered water to make it taste worse than it did! I really like this item and have recommended it to family members.

I love this water system. It was easy to install and the replacement filters are affordable. The quality and taste of the water is excellent. I have had this system for over a year and it has been easy to maintain and keeps delivering consistent quality water and water pressure. I am also very impressed with the company and customer service. When I called to ask a question about a small leak, Sean answered the phone, I was stunned to get a person immediately. He answered all my questions and offered me a quick solution to my problem. He followed up with and email about our conversation and made sure that my problem was resolved. I was so impressed that I wish there were more people like Sean and more companies like Ispring out there. They definitely set a high standard on quality products and customer service!! That's rare in todays world!!

This was an easy install. I was tired of waiting for the water to be filter on my Brita when it was low so I made the purchase. The installation was pretty straight forward and simple to do. Quality feels solid and will last a while. I did have to drill into my sink but that was easy. Just make sure you connect the right outlet to get cold water instead of hot water. Whoops...lol. did the installation in about 30mins. Straightforward and easy to do. Came will everything you need to install it besides the tools. The filters are secured tightly under the sink and to my surprise, it didn't take up too much room. I live in an older house so I am concerned about the water pressure when adding this filter. To my surprise, it didn't change anything. It actually pretty quick to fill up glass of water. I reached out to Sean because during the installation, the red C-Clip jumped off and fell into a cevass. He immediately sent one out to replace it. Quick no questions asked. 5-start customer service. If anything changes I'll be sure to update it here but so far happy with the install and the clean water.

Affordable, easy to install.When I was searching for water filters .. initially I looked for RO systems .. I came to know that with the RO systems the water will become little acidic. Later I found this product and felt this is what I was looking for. Very easy to install. The first few days I saw many bubbles in the filtered water I was little scared to drink .I contacted the customer care and Mr John clearly explained me that the bubbles are very common when we use the new filter. Thank you John for your support

I installed the iSpring US31 under-sink water filter system recently and have been very happy with it so far. The installation was surprisingly easy, and the package came complete with all the hardware, tubing, faucet, and filters needed to get everything set up. The instructions were clear, and the overall build quality feels solid. After installation, the water tasted noticeably cleaner and fresher right away. It’s a great system if you want better drinking water without dealing with large countertop filters or bottled water. Overall, a very good value and a well-designed kit.

Fantastic Kit. Very nice quality. Great packing and easy setup. This is a no brainer. We drink tons more water because of it. Fit right into a small cabinet under the sink. I'll try and grab some pictures to add. The water tastes great, so it must be doing a great job filtering because I couldn't stand the taste of our city water before.

This system is not NSF certified. There is a database. You can look it up. The filters themselves are only certified to work in a reverse osmosis system as pre-filters. Reverse osmosis itself removes everything, so the pre-filters don't need to remove lead etc. These aren't certified to do anything on their own. I assume they do remove actual sediment and possibly improve flavor since there is apparently charcoal in them, but they aren't even certified even at that basic level. Even common pitcher filters have NSF certification. I would absolutely not trust these for water with suspected lead or other heavy metals, and certainly not for PFAS, medications or microbes. I'm returning the system unused. Wish I would have done this research first. We're inclined to believe the claims in product descriptions and think "they can't get away with outright lies, right? Yes they can. Update: I emailed i-Spring and the rep confirmed they aren't certified and that the description here is misleading

最初はちょっとフィルターの味したが、すごく設置しやすい、いい製品です

Haasta el moment funciona exelentemente.

Das Spring US31 3‑stufige Trinkwasserfiltersystem hat sich als ausgezeichnete Basislösung erwiesen. Die drei Filterstufen arbeiten zuverlässig und liefern bereits ohne weitere Erweiterungen sehr sauberes Wasser. In Kombination mit einer zusätzlich erworbenen Osmosemembran wird das System jedoch zu einem ideal abgestimmten Komplettset, das einen perfekten Einstieg in die Welt der hochwertigen Wasserfiltration bietet. Die Installation ist unkompliziert und das gesamte System wirkt durchdacht. Die Verarbeitungsqualität ist hervorragend – stabile Gehäuse, solide Anschlüsse und hochwertige Filtereinsätze vermitteln einen langlebigen und wertigen Eindruck. Fazit: Ein starkes, sauber verarbeitetes Filtersystem, das sich besonders in Kombination mit einer Osmosemembran als perfekter Start für reines Trinkwasser eignet. Klare Empfehlung.

Well made product and very easy to install. Particularly impressed with the quality of the filter housings. Once installed it took a few days for the water to completely clear, but I think that that was just down to the new filters. Water taste is great as is the flow rate. Only slight criticism is the small clip fittings for the pipe work, however I think that this is the same design on most new filter systems. Overall would highly recommend, especially at the price.

Great filter system works brilliantly. Easy to fit, took about 30 minutes. Had slight issue with tap and had a very quick replacement turnaround, customer services were fantastic. Now enjoying really great tasting filtered water.
