Captive Purity Hi-Silicate Removal TFC Replacement Membrane 35GPD Information




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 unit. We have researched and tested the best replacement membranes among all manufacturers, and offer only the best available.




Manufacturer Info

Captive Purity manufactures water filtration and water testing supplies for marine and reef aquaria. The brand is best known for their high-quality line of reverse osmosis filter systems and accessories. Captive Purity also produces refractometers for testing salinity, portable pen-sized meters for testing pH as well as replacement filter media for their RO and RO/DI filter systems.

Comments: I went for a higher output membrane expecting a modest improvement in replacement time after a water change. Today, 24 hours after a 20 gal change my reservoir is full again. Fantastic

Comments: I bought one of the 75gpd membranes 2 years ago and ever since I have gone through my DI cartridges like crazy. I had changed the flow restricter at the same time. I finally bought some dual tds monitors to check the in/out on my ro and another one to monitor my dual di cartridges. That monitors showed that the tds in/out on the ro membrane was exactly the same at 34ppm. So I installed my old spectrapure 50 gpd membrane that is over 10 years old which I had saved by putting it in a sealed bag with some ro water in the frig. Now the tds monitor show 34ppm in and 0 ppm out. I only gave three stars because I am not sure what the problem was with this membrane. The only reason I was changing membranes was to up the gallons per day. My old membrane was still going strong whem I replaced it. Needless to say I am now sticking with all the highest quality replacement sediment, carbon and di filters frm spectrapure. Well that showed 34ppm in and 0 ppm out.
