The key component for any reverse osmosis unit is its membrane. The membrane will determine the type of contaminants removed and how much water the unit will produce. Our Captive Purity Hi-S (High Silicate) membranes are the gold standard and will remove 96% of nitrates and up to up to 99.5% of silicate. Chlorine will ruin TFC, Hi-F, and Hi-S membranes so prior carbon filtration is required. All Captive Purity Membranes and RO and RO/DI units are designed and manufactured in the USA.

Please note that these Hi-S replacement membranes are interchangeable with Kent Marine, and SpectraPure RO or RO/DI units. For proper and efficient operation please check that your RO or RO/DI unit has the proper Flow Restrictor installed. All sizes of Flow Restrictors are available separately. We have researched and tested the best replacement membranes among all manufacturers, and offer only the best available.

Average

it is what it is by NOLAN SHEARER

Experience Level: Intermediate

Posted on 3/12/2009 from NORFOLK, VA UNITED STATES

Comments: No actual branding on product, and could not find a connection between membrane manufacturer and Captive Purity. Upon some research found out it is just a generic membrane made in some country like Korea. Unsure of true quality, seems cheaply made compared to my old membrane, but seems to work so far.
I would not recommend this product to my friends.
