iSpring F21KU75 2-Year Reverse Osmosis Water Filter Replacement for 7-Stage 75GPD RO Alkaline UV Systems, Fits RCC7AK-UV

The iSpring 7 stage RO 2-year filter set is perfect. It comes with all filters to be changed at the prescribed intervals.In the shipping box, each filter has its own compartment to prevent transport damage. Each filter has a paded sleeve and is shrink wrapped to keep them sterile.I test my RO system water with electronic instruments and can say with certainty that the iSpring (123Filter.com) filters and system provide clean, safe, and pure drinking water. The filters sold by iSpring are top quality and last as advertised.Other economy filters are just that. State water lab testing has proven that economy filters I purchased either did not work as well or last as long as advertised. In addition, I am confident that the high-quality. filters from iSpring (123FILTER.COM) will not introduce contaminates into my drinking and cooking water. I can not say the same for the economy brands.As an engineer, I am very thorough and scientific about my selection of products, especially for water used by my family for drinking and cooking. My refrigerator is supplied this same top quality water for great ice as well.We also give our dog this drinking water and are adamant about safe, pure drinking water for pets.I appreciate the iSpring customer support team. They are very patient and helpful. Kudos to Nick who has repeatedly answered my questions and assisted with filters selections that best suit our household usage.Top shelf products!MoTown Mark at the BeachMyrtle Beach, SC"

Good product and was simple to install 35-40min include washing and cleaning the cartridges

Folks, Unfortunately, the water in the part of NC that I live in is substandard. And I have spent countless hours researching and have owned several different water filtration systems over the past decade+. I have learned lots of lessons along the way to include the importance of making sure water filter is NSF certified. I can say without a doubt, my iSpring RO water filter with UV sterilizer is the best by far. Not only for performance, but also for the price to purchase and maintain. In my house, we only drink and cook with water from our RO filter! Great purchase, well worth the investment!

It's about time to change my filter. This product is original from iSpring. It has very clear installation and does work pretty well. (The old filter I took our is all muddy and sanded while the new one shows pure white, meaning the filter is actually working well)

Nick at ISPRING customer support is the best. He is always so helpful, give me all the info I need and explains things so well. He is vey knowledgeable . Always communicates detailed info to help us out can go wrong buying from this company!
