Marine Depot Hi-Silicate Removal TFC Replacement Membrane 50GPD 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 Marine Depot 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 Marine Depot 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.

Comments: I bought this unit to replace my spectrapure 90 GPD Filter. I have a 4 stage RO/DI filter and replaced the Other 3 filters also. We have well water where I live and This unit has been great. The new RO filter is working As I expected! So far I've only had to produce a 6 gallon Bucket of top off water. Only took 1 hour and 20 minutes! My TDS meter read 0 on the output end! I'm happy with it and would recommend it to others
