I would use these again - I use 4 of these in my maple sap concentrating set up and they work great! I would use these again, but next time I need filters (not any time soon I hope) I will upgrade to the 150GPD ones. I have used these to run over 1200 gallons of sap this year with no issues so far! I can get sugar up to 8-9% without any sugar passing into the permeate. I did try it up to 12% but then I was getting a small amount of sugar passing into the permeate.

I've been using this RO membrane in the same unit for 5 years now. I take regular TDS readings and look for a spike in my readings as an indication to change, and I've seen no spike, but have opted to changed anyways as the one in my RO was 3 years old. This has a very long service life in normal residential use. All of our drinking and cooking water goes through this and it's better than any bottled stuff you can buy. In addition to our drinking and cooking water, in the winter months, all of my humidifier water comes from my RO unit. This is approximately 15 gallons a day for 5 months. The only time I clean my dehumidifier is when I put it away for the season. Otherwise I never have to descale or otherwise clean it while it's in use. ## Frequently Bought Together - Filmtec TW30-1812-100 100 god Membrane, 12x2x2, Blue - Omnipure CL10ROT33-B 1/4" FPT Inline Filter - Pentair Pentek P25 Sediment Water Filter, 10-Inch, Under Sink Spun-Bonded Polypropylene Replacement Cartridge, 10" x 2.5", 25 Micron,White --- ## 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/3672737-filmtec-tw30-1812-100-100-gpd-filmtec-residential-ro-membrane](https://www.desertcart.us/products/3672737-filmtec-tw30-1812-100-100-gpd-filmtec-residential-ro-membrane) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-12*
