From the Manufacturer Perfect for Reverse Osmosis DI Water System - Remove Hard Water material - To be replaced every 500-1000 gallons of water, produce 0ppm for your water - Fit 1/4" Fitting (not included) - Clear housing for easy view of media status - Refillable Review: Awesome! - Working great so far and yielding 0 ppm Review: Working great so far and yielding 0 ppm - Working great so far and yielding 0 ppm. Connected to the output of an RO system. Had it for several weeks and I see little or no color change. But I haven't tried replacing the resin yet. Didn't come with fittings which is annoying, but fortunately I had fittings from another DI filter that didn't work. Standard RO system 1/4" tube fittings work. You want the fittings that are threaded on one side to fit a cartridge. You can insert a 1/4" bare tube, even one that you cut, and tighten. Then screw that into this cartridge. Update: After a year it was putting out 22 ppm (30 ppm in from RO). Next time maybe I'll replace after 6 months. Opening and refilling it was easy. Opening took some oomph, but I didn't need a tool. Due to all the 1 star reviews about breaking it, I didn't tighten it very much when reclosing. Only snug. I don't think this little force could ever break anything. Even so it is leak free. You may want a tool to open it, but when you close it please just do hand tight and don't muscle it. Or you might be the next 1 star reviewer who broke your filter. ## Features - Advanced DI Filtration: Utilizes ion-exchange resins to remove mineral ions, leaving water free of hardness and preventing scale buildup.

The first reply I received was a direct solution. Not only him, but this is the second time I've contacted customer support at iSpring for a variety of issues and they've always been exceedingly pleasing. May the forces that be give the man a bonus, raise, because he made a lifelong customer outta me. Thanks for the wonderful customer experience. Now, on the system: it's main use was for drinking, cooking and miscellaneous cleaning around the house. However, I've caught a bug and now use it for all my fish tanks. It's perfect for aquarium use, grows great plants, and will filter my pH=8,dgH=0, dkH=14, TDS=300PPM water to 0ppm and undetectable level of Mg, Ca, and CaCO3. If aquarium is what you want, you've found your product. ## Frequently Bought Together - iSpring FD15 DeIonization Replacement Filter Fit RO/DI Water Filter System for Aquarium, 10" x 2.5", 1 Count - iSpring FA15 Alkaline Inline Water Filter Cartridge, 10” x 2” with 1/4” Quick Connect, NSF Certified, Add-on for RO Systems, Balances pH & Restores Minerals, 3-Layer Replacement Filter - iSpring ACL1 RO Add-on Filter Kit For Standard Reverse Osmosis Systems, 1/4" --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/11052489-ispring-fd15-deionization-replacement-filter-fit-ro-di-water-filter](https://www.desertcart.id/products/11052489-ispring-fd15-deionization-replacement-filter-fit-ro-di-water-filter) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-01*
