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

Worked perfectly

I purchased the 50 gallon membrane, my water is between 450 and 475 ppm on my tds meter from the tap and 25-27 from the ro tap, which is about 94-95% removal, which is almost identicle number to the one I replaced.

WORKS GREAT..

I installed the new one in my RO system and it worked perfect. I suggest getting a rubber strap wrench to hold the body of the tube it goes to keep it from turning

I ordered a "Five-Pack" of RO filters. It was scheduled to be delivered by July 8 2025, but arrived early on the 1st. However, it came in two packages delivered by two different services. The first package was delivered early in the morning on the 1st and I was sent a message that my order had been delivered. When I collected it from the front porch there was only one filter and notes or indication that a second separate package with the remaining four filters would be delivered later by a different delivery service.The filters look good and as far as I can tell for the moment are a near copy of the original filters, but at a lower cost. So, other than a little confusion about the delivery the product seems okay.

100 gpu or greater is better

Standard 50gpd membrane, fit standard housing and was easy to swap out. Appears to be doing it's job. After 1 week of use, TDS is measuring 4.5ppm on a 5 stage system with an additive final stage. Haven't measured right after the membrane, but I suspect it would be even lower.

Quality product, arrived on time and in good condition. Easy to install. After flushing new membrane several tankfuls, good quality water. Testing confirmed tds of less than 20 ppm from a water source of over 425 ppm . Good value, good tasteless water. Would recommend
