Key Features

• 50 GPD THIN FILM COMPOSITE MEMBRANE - The reverse osmosis membrane is the stage that does the separation, passing water through while rejecting dissolved solids to the drain line. Rated 50 gallons per day at 60 psi and 77F. Standard 1812 form factor. Install with the pre-filters fresh so chlorine does not reach the membrane.
• FITS THESE SYSTEMS - Direct replacement for RS9-TFM-50, RS-50TFC, TFCRS950, UF-50, UF-50T, UF50N, 21179, 21191, 9591, 9747. CFS is an independent brand and this is not an OEM product. Manufacturer names and part numbers are used for reference only.
• WHERE THE MEMBRANE SITS IN THE SYSTEM - The membrane is the third or fourth stage, after sediment and carbon have taken out the grit and chlorine. Chlorine damages thin film composite membrane material, so the carbon stage ahead of it is what keeps the membrane working. Change the pre-filters on schedule and the membrane lasts as designed.
• WHAT TO EXPECT ON SERVICE LIFE - A membrane typically runs about 2 years on well-maintained systems, longer on soft low-TDS water and shorter on hard or high-TDS supply. Watch your TDS meter rather than the calendar: when output TDS climbs toward feed TDS, the membrane is done. Flush a new membrane for several hours before drinking.
• GPD IS A RATING, NOT A PROMISE - Gallons-per-day figures are measured at 60 psi and about 77F. Colder water and lower line pressure both reduce output, which is normal and not a fault. If your production seems low, check line pressure and water temperature before replacing anything.
