Review: The filters were easy to install initially and the replacement process is the same. - The filters can produce up to 75 gallons of clean fresh water a day and it is a reverse osmmosis system. The installation was an easy straight forward process. No electric was needed and nothing special was needed in the way of tools. No professional plumber was needed. I am extremely happy with the unit. I scanned the QR code to register for my 1 year warranty and contacted the company for information on an extended warranty. Nick responded almost immediately and informed me that he processed my warranty and upon completion, the unit received a 3 year warranty. I did not have to spend a dime extra. Nick was very helpful and knowledgeable about his different products. I decided to purchase the 3 year filter kit and I also purchased a extra MC7 reverse osmosis filter just too have it in addition to the one that came with the other filters. I am very satisfied. ## Features - Experience clean, safe, and good-tasting water every time you turn on the faucet; Enjoy crystal clear ice cubes, fresher tea and coffee, better tasting foods, healthier baby formula – even better than most bottled water - Fits iSpring Reverse Osmosis Alkaline PH Water Systems and most other brand name RO systems - Gives back healthy minerals such as natural calcium, magnesium, sodium, potassium ions - Produce perfectly PH-balanced alkaline water ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BNGRIX2 | | Best Sellers Rank | #34,051 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #217 in Replacement Under-Sink Water Filters | | Brand | iSpring | | Brand Name | iSpring | | Compatible Water Purifier Models | Aquaphor Crystal, iSpring RCC7AK | | Customer Reviews | 4.8 out of 5 stars 696 Reviews | | External Testing Certification | ANSI | | Global Trade Identification Number | 00662425058525 | | Included Components | water filters | | Item Dimensions D x W x H | 16"D x 11"W x 16"H | | Item Type Name | iSpring F28K75 3-Year Filter Replacement Supply Set For 6-Stage Reverse Osmosis RO Water Filtration Systems with Alkaline Mineral Filter | | Item Weight | 10.2 kg | | Manufacturer | iSpring | | Manufacturer Part Number | F28K75 | | Material | Activated Carbon,Carbon | | Material Type | Activated Carbon,Carbon | | Model Number | F28K75 | | Number of Items | 1 | | Number of Packs | 1 | | Product Benefits | Removes dirt, rust, sand, particles, chlorine, and organic contaminants for clean, safe, and good-tasting water; Produces 75 gallons of water per day; Compatible with various RO systems for easy installation and replacement; Provides healthy minerals and long-lasting performance | | Product Dimensions | 16"D x 11"W x 16"H | | Set Name | iSpring 3-Year RO System w/AK Filter Set | | UPC | 662425058525 | | Unit Count | 1 Count | ## Product Details - **External Testing Certification:** ANSI - **Item Weight:** 10.2 kg - **Material:** Activated Carbon,Carbon - **Product Dimensions:** 16"D x 11"W x 16"H ## Images ![iSpring F28K75 NSF Certified 3-Year Replacement Set for 6-Stage Reverse Osmosis RO Systems with Alkaline Mineral Filter, 28 Pieces, White - Image 1](https://m.media-amazon.com/images/I/81uosMQ4JbL.jpg) ![iSpring F28K75 NSF Certified 3-Year Replacement Set for 6-Stage Reverse Osmosis RO Systems with Alkaline Mineral Filter, 28 Pieces, White - Image 2](https://m.media-amazon.com/images/I/71gCSqgaO1L.jpg) ![iSpring F28K75 NSF Certified 3-Year Replacement Set for 6-Stage Reverse Osmosis RO Systems with Alkaline Mineral Filter, 28 Pieces, White - Image 3](https://m.media-amazon.com/images/I/71s13-IdA-L.jpg) ![iSpring F28K75 NSF Certified 3-Year Replacement Set for 6-Stage Reverse Osmosis RO Systems with Alkaline Mineral Filter, 28 Pieces, White - Image 4](https://m.media-amazon.com/images/I/71L1eHpcH9L.jpg) ![iSpring F28K75 NSF Certified 3-Year Replacement Set for 6-Stage Reverse Osmosis RO Systems with Alkaline Mineral Filter, 28 Pieces, White - Image 5](https://m.media-amazon.com/images/I/71E4eODT7FL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 3-year filter replacement supply, which is very reasonably priced. *by G***R on April 24, 2026* I recently purchased the iSpring RCC7AK 6-Stage Reverse Osmosis System and it arrived exactly on schedule.

Thank you iSring team for the great RO water filter and wonderful customer service. ### ⭐⭐⭐⭐⭐ The filters were easy to install initially and the replacement process is the same. *by M***R on September 16, 2026* The filters can produce up to 75 gallons of clean fresh water a day and it is a reverse osmmosis system.

I am very satisfied. ### ⭐⭐⭐⭐⭐ Excellent value & taste, filter replacement is very simple *by J***R on March 4, 2015* After about 13 months of use with my NON-iSpring 6-stage RO system installed last year by a local vendor, the water taste had noticeably changed. By then, I'd been trying to schedule for weeks a date/time with the same vendor for filter replacement. When the tech finally came, he didn't have the alkaline filter with him... I said goodbye to him, and onto Amazon I went. These filters fit perfectly with my RO system. This is by far the best bargain for RO filters, and even includes a replacement membrane (replaced every 3 years). The local RO shop charges ~$150 to replace the 6-stage filters annually (not the membrane), and that's with the "6 months" filters being used for 12 months, and since iSpring's includes 6 of the "6 months" filters, it's an even better value. And you can replace the filters at your own convenience. Only caveat was I had to call iSpring to request 4 free quick-fit adapters to thread onto the stage 5 & 6 filters (my previous ones had quick-fit built into the filter cases), with several wraps of Mr. Gasket 2842G Teflon Tape (can leak otherwise). Phone support was very prompt and helpful. Check YouTube for simple "RO filter replacement" videos. You'll want to clean the Stage 1-3 filter canisters (the big vertical ones), since they get grimy after a year. If you don't already have a horizontal mount for the stage 5 or 6 filters, I'd recommend S5-TO-S6 RO Kit for 2.5" diameter Inline Filter (buy 2 if you need a pair for both filters), which will keep the stage 5 & 6 filters stable and less prone to hose leakage. --- [Update 02/02/2016] I just replaced replaced the second set, and water's still awesome. A friend had even commented how good our water tastes, although we didn't even mention our R.O. system! ## Frequently Bought Together - iSpring F28K75 3-Year Replacement Supply Set for 6-Stage Reverse Osmosis RO Water Filtration Systems with Alkaline Mineral Filter, 28 Piece, White - iSpring RCC7AK 6 Stage Reverse Osmosis Water System Under Sink with Alkaline Remineralization, NSF Certified, 75 GPD, TDS Reduction --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/8266048-ispring-f28k75-nsf-certified-3-year-replacement-set-for-6](https://www.desertcart.com.pa/products/8266048-ispring-f28k75-nsf-certified-3-year-replacement-set-for-6) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-12*
