ULP 4040 Membrane, 2600GPD, 99.3% Salt Rejection, 7 Pounds, 1 Count, Commercial Water Filtration Membrane, 1 Membrane

This is the best membrane system for water filtration easy works very good water tastes great

Before I even received my membrane, the seller contacted me to inform me that they would be more than happy to replace or refund for any reason once I received it. First thing I’ve ever ordered on Amazon and received a return guarantee for an item even if used. Also, the price and value of the product is very good. For just $120, you get a filter that compares with any local product that could cost twice the amount. I am using it in an RO DI window cleaner water purifier. I use a sediment and carbon filter before running into the RO filter. Then, the clean water goes into a DI tank. Out of that comes pure water with a TDS of 0ppm. I highly recommend the product because of the price, value, and awesome customer service.

This product is a great value for the price. It is not the most expensive out there, but it performs just as well as some of the more expensive models. I am always on a budget so this is definitely a good option.

Perfect fit for my full house RO system.After flushing out my system after installing. It was obvious that the water was being cleaned immediately!

Piece of garbage / I bought three and they lasted less than 2 months and lost 90% of Filtering capabilities in two days…completely collapsed
