About This

• 50 GPD THIN FILM COMPOSITE MEMBRANE - One polyamide TFC reverse osmosis membrane rated at 50 gallons per day, the standard 11.75 by 1.75 inch element that fits most under sink RO systems. This is the stage that does the actual reverse osmosis and reduces total dissolved solids.
• MATCH THE RATING TO YOUR SYSTEM - 50 GPD is the lower production rate in this range and it suits most household systems. Higher ratings fill the tank faster but send more water to drain doing it, so check the number on the membrane you are removing rather than assuming higher is better. Gallons per day is production under ideal pressure and temperature, not what comes out of your tap; real output is lower and the storage tank covers the gap.
• FITS MOST STANDARD UNDER SINK RO SYSTEMS - The standard 1812 element used by APEC ROES-50, ROES-75, ROES-100, RO-90, RO-45; GE GXRM10RBL, GXRM10G, GXRV10; Olympia OROS-50, OROS-80; Watts WP-4V, WP-5, RO-TFM-4SV, RO-TFM-5SV, WPRL-58 and ZeroWaste; Krystal Pure KR10, KR15; plus HDLORF4, PNRV12, RO5MX, RCC100P, RCC7, F5-75, RFK-5, CMP10-F, Culligan 1000R, Simpure SP4-RO75, TGI-525, H5000 and HX-RO.
• CHANGE THE CARBON PREFILTERS ON TIME - Chlorine damages thin film composite material, so a spent carbon prefilter is not just a taste problem; it is passing chlorine straight to the membrane. Prefilters change every six months, the membrane every two to three years. Fitting a new membrane behind an old carbon block wastes it.
• HOW TO TELL WHEN IT IS SPENT - A rising TDS reading points at the membrane. Falling flow at the faucet usually points at the prefilters instead. A membrane is not a taste stage and not a softener; it does not change your water hardness. Compatible replacement membrane, not an original manufacturer part.
