However I can offer you this. This is the standard in filtration systems as I know it. If the membrane meaning the RO membrane can fit in a housing that is designed for it then usually that means it will work. So an example would be if you had a 10 inch long 2 1/2 inch diameter housing for a membrane you would roughly need a 10 inch long 2 1/2 inch wide membrane lol. Something helpful for the future as well. Whenever I purchase anything I keep the instruction manual for it in the same place for everything I own. That way if I have a question I can simply go to my “library” and find my answer lol. **Q: Will this work with an ultima vii system?** A: Your system makes 24gpd, The membrane filter your asking about makes 50gpd. You can upgrade your system to 50gpd by making some changes to the flow restrictor. Go to utube and view numerous videos on RO systmes. The filter will work only after some changes to your system. ## Customer Reviews ### ⭐⭐⭐⭐⭐ RO membrane cartridge. *by F***D on April 27, 2026* Perfect fit for my RO BUDDIE. Easy to install. Output RO water PPM is around 4 to 5 ppm. Great way to rejuvenate my RO system. Great value. ### ⭐⭐⭐⭐⭐ Lower measurement *by M***R on March 15, 2026* Great filter, arrived quickly and price is good. Easy to install and package well. Water tastes great. TDS measures 29ppm after install before it was 80ppm. Water at non filter, measured 600ppm. The 29ppm will drop after some use. ### ⭐⭐⭐⭐⭐ Reliable, durable, and great support for maple sap concentration *by B***S on May 1, 2026* I use the Membrane Solutions 400 GPD RO membrane for concentrating maple sap, and it’s been a strong performer. It consistently boosts sugar concentration, cutting boil time and fuel use. Even when pushed toward its upper performance limits, it continues to run reliably without major drop-off when the system is set up properly. The membrane cleans up very well and has held performance over multiple seasons with proper flushing and storage—definitely adds to its value. Customer service is also excellent. They were responsive and helpful with setup questions, which is a big plus when adapting this for sap instead of standard water use. Bottom line: Great performance, easy to maintain, long-lasting, and well-supported. I’d buy it again. ## Frequently Bought Together - Membrane Solutions 75 GPD RO Membrane, Reverse Osmosis Membrane Element 11.75" x 1.75" Water Filter Replacement for Undersink Home Drinking RO Water Filtration System - iSpring FT15 5th Stage Inline Post Carbon Water Filter, Replacement Cartridge with 1/4" Quick Connect for Refrigerator, Ice Maker, RO Reverse Osmosis Water Filtration System(1 Pack) - iSpring F7-GAC for Standard 5-Stage Reverse Osmosis RO Systems 1-Year Replacement Supply Filter Cartridge Pack Set, 7 Count --- ## 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.tw/products/44762706-75-gpd-ro-membrane-reverse-osmosis-membrane-element-11-75](https://www.desertcart.tw/products/44762706-75-gpd-ro-membrane-reverse-osmosis-membrane-element-11-75) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-18*
