The sediment filter catches particles and debris, while the GAC and carbon block filters remove chlorine, unpleasant smells and improve the taste of the water. Together they leave the water clean, fresh and far more enjoyable to drink. They're easy to install, fit perfectly and work exactly as advertised. The difference is noticeable, especially when it's time to replace them. With what we pay for water these days, you'd think we wouldn't need extra filtration. But every time I change these filters and see what they've removed, I start wondering if the water companies should be using them too. Review: I have these on a rolling 6 month order - These are good. I have them installed in my auto water change system. They filter out any crud and declorinate water. I do daily small water changes and these do the job well. They aren't expensive and are easy too replace. ## Features - Individually wrapped 6-month high capacity prefilter replacement cartridge pack for most standard RO filtration systems. - 3 pieces of 10" x 2. 5" replacement water filters included: 1x sediment filters, 1x granular activated carbon filters, and 1x carbon block filters. - This filter pack does NOT include an RO membrane. - Experience clean, safe, and good-tasting water every time you turn on the faucet. - If you have trouble installing the filters, please refer to the user manual or contact us. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00NQF490I | | Benefits | Delivers clean, safe and good tasting water | | Best Sellers Rank | 13,072 in DIY & Tools ( See Top 100 in DIY & Tools ) 6 in Under-Sink Filters | | Brand | iSpring | | Brand Name | iSpring | | Compatible Water Purifier Models | iSpring RCC7 | | Country Of Origin | China | | Customer Reviews | 4.7 out of 5 stars 2,444 Reviews | | EU Spare Part Availability Duration | 9 Months | | External Testing Certification | NSF/ANSI | | External testing certification | NSF/ANSI | | Global Trade Identification Number | 00662425070145 | | Included Components | Water filters | | Item Dimensions D x W x H | 21.5D x 8.5W x 27.2H centimetres | | Item Type Name | 6 momth Cartridge | | Item Weight | 0.01 Ounces | | Item weight | 0.01 Ounces | | Manufacture Year | 2021 | | Manufacturer | iSpring | | Manufacturer Part Number | F3 | | Material | Activated carbon , Sediment | | Material Type | Activated carbon, Sediment | | Model Number | F3 | | Number of Items | 3 | | Product benefits | Delivers clean, safe and good tasting water | | Product dimensions | 21.5D x 8.5W x 27.2H centimetres | | Set Name | Replacement Filter Pack Set | | UPC | 662425070145 | | Unit Count | 1.0 count | ## Product Details - **External testing certification:** ANSI - **Item weight:** 0.01 Ounces - **Material:** Activated carbon, Sediment - **Product benefits:** Delivers clean, safe and good tasting water - **Product dimensions:** 21.5D x 8.5W x 27.2H centimetres ## Images ![F3 6-Month Prefilter Replacement Supply Filter Cartridge Pack Set for Standard Reverse Osmosis RO Systems, F3, White - Image 1](https://m.media-amazon.com/images/I/71do8xBHSiL.jpg) ![F3 6-Month Prefilter Replacement Supply Filter Cartridge Pack Set for Standard Reverse Osmosis RO Systems, F3, White - Image 2](https://m.media-amazon.com/images/I/71nWeV176YL.jpg) ![F3 6-Month Prefilter Replacement Supply Filter Cartridge Pack Set for Standard Reverse Osmosis RO Systems, F3, White - Image 3](https://m.media-amazon.com/images/I/71s13-IdA-L.jpg) ![F3 6-Month Prefilter Replacement Supply Filter Cartridge Pack Set for Standard Reverse Osmosis RO Systems, F3, White - Image 4](https://m.media-amazon.com/images/I/71L1eHpcH9L.jpg) ![F3 6-Month Prefilter Replacement Supply Filter Cartridge Pack Set for Standard Reverse Osmosis RO Systems, F3, White - Image 5](https://m.media-amazon.com/images/I/71lnILeqhKL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Can this set of replacement filters be used for the iSpring US31?** A: Hi, Yes, these filters are compatible with the unit model US31.
