Captive Purity Hi-Silicate Removal TFC Replacement Membrane 25GPD 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.
