Operating at 90 psi will remove 2/3 of the water. Hobby level producer with under 100 taps. ### ⭐⭐⭐⭐⭐ These were better than the expensive Hydrologic replacement 150 membranes! *by on Reviewed in the United States May 20, 2019* I made a RO unit for maple sap using the Hydrologic Stealth 300 and it took the sap from 2.1% to 3% sugar with one pass. I replaced the membranes from a local store to get me started this past spring at $80 a pop! Since we doubled the number of taps we needed to increase the efficiency of the RO unit and I added 5 pairs of 150 membranes and housing to the unit in series and now can take the sap in one pass from 2.5% to 4.5% sugar. But the real difference is in the "pure" water which isn't as we learned last year when my wife used it in the iron (yes it was a mess). The Stealth 150s let 0.50% sugar through where these units let only 0.15% which for us means less sugar wasted and more syrup (about 3 gallons more per 1000 gallons of sap)! This also means the water is more pure than before, and at 1/4 the cost. ### ⭐⭐⭐⭐⭐ Works great 👍 *by on Reviewed in the United States March 24, 2026* It's been seven years, and the membrane is still working great. We have 170 ppm in the pipelines, and 3 ppm at the filter outlet. I had to add a booster pump because the pipelines are at 40-45 psi. This membrane works best at 90 psi, where I achieve 3 ppm. ## Frequently Bought Together - Membrane Solutions 150 GPD RO Membrane, Reverse Osmosis Membrane, RO Membrane Replacement, Reverse Osmosis Filter Replacement for Under Sink Home Drinking RO Water Purifier System (2 PACK) - Membrane Solutions 5 Micron 2.5" x 10" CTO Carbon Block Water Filter Cartridge Replacement for Whole House Filtration Systems, Compatible with WFPFC8002, WFPFC9001, FXWTC, WHEF-WHWC, WHCF-WHWC, 6-Pack - Membrane Solutions 5 Micron 10" x 2.5" Sediment Water Filter Replacement Cartridge for Any Water Filter 10 x 2.5 inch Whole House RO System, Compatible with GE FXUSC, Aqua-Pure AP110, WHKF-GD05-6 Pack --- ## 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/64490298-membrane-solutions-150-gpd-reverse-osmosis-membrane-nsf-ansi-58](https://www.desertcart.co.za/products/64490298-membrane-solutions-150-gpd-reverse-osmosis-membrane-nsf-ansi-58) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-14*
