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 ### ⭐⭐⭐⭐⭐ Good product, great price *by R***N on 9 November 2025* Works well ### ⭐⭐⭐⭐⭐ Good R/O Membrane Replacement *by M***N on 11 March 2025* Fits and works as expected. ### ⭐⭐⭐ المنتج 50 جالون ماينفع *by R***I on 6 November 2022* الفلتر كفو وجودة ممتازة بس 50 جالون لا انصحك فيه خذ نفس المنتج بس 75 جالون افضل من هذا ## Frequently Bought Together - Membrane Solutions Reverse Osmosis Membrane 50 GPD 11.75"x1.75" RO Membrane Water Filter Replacement Fits Under Sink RO Drinking Water Purifier System 1-Pack - APEC FI-ES-TCR-QC 10" High Capacity Inline Carbon Filter with 1/4" Quick Connect Stage-5 For Undersink Reverse Osmosis Water System --- ## 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.co.za/products/274783843-membrane-solutions-reverse-osmosis-50gpd-ro-50-gpd-water-filter](https://www.desertcart.co.za/products/274783843-membrane-solutions-reverse-osmosis-50gpd-ro-50-gpd-water-filter) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-07*
