Exactly what I needed .it Works ### ⭐ If I could give it 0 stars I would *by A***R on 12 April 2024* Just plain doesn’t work, tried everything but membrane doesn’t give me clean water. ### ⭐⭐⭐⭐⭐ Looks good to me! *by L***U on 18 May 2024* I got this as a replacement membrane for my 2400 GPD whole-house RO system. It looks just like the membrane I have in it now, so...pretty sure it's going to work! And the price...what a deal. You'll need a 4-40 housing for this, btw. Definitely a step up in RO performance from the smaller less commercially oriented systems. 5 stars. ## Frequently Bought Together - BW-4040 Osmosis Membrane High Performance Commercial Industrial,BW-4040 Ro Filters for Desalination,4"x40" High Salt Rejection,Energy Efficient, Reverse Osmosis Membrane Industry (2400GPD) - Max Water - Heavy Duty - Reverse Osmosis 4040 Membrane Housing - 4" x 40" good for industrial use - 4040 housing - End Cap with 2 O-Rings for 4" Stainless Steel RO Membrane Housing --- ## 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.us/products/647925604-ulp-4040-reverse-osmosis-commercial-ro-membrane-2600gpd-ulp-4040](https://www.desertcart.us/products/647925604-ulp-4040-reverse-osmosis-commercial-ro-membrane-2600gpd-ulp-4040) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-09*
