5 Stage TFM Membrane Standard Reverse Osmosis System:
If you have a 5 stage reverse osmosis system that uses a TFM membrane, we sell compatible replacements.
Our standard replacement filters are approximately 10" x 2.5". You should confirm that your filter housings will hold a 10" x 2.5" filter.
A standard membrane housing holds an 11.75" to 12" inch membrane. Confirm your membrane housing will hold the membrane. If your membrane housing is not standard, you can replace it with the standard MH09-1812WH Membrane Housing.
Reverse osmosis systems have a flow restrictor in them. The flow rate of the restrictor must match the membrane flow rate (gallons per day). Choosing the membrane with the correct gallons per day is important. You will find the gallons per day of your membrane on the actual membrane itself or consult your user's manual. For more about flow restrictors see flow restrictors.
5 Stage Standard Reverse Osmosis System with TFM Membrane Replacement Filters and Membrane:
Stage 1: P5-10-WF. Replace approximately every 6 months.
Stage 2: EP5-10-WF. Replace approximately every year.
Stage 3: CBC-10-WF. Replace approximately every year.
Stage 4: Replace approximately every 2 years. To find the correct membrane, check the gallon per day (gpd) rating in your user manual or remove your current membrane. Your current membrane will indicate the gpd. For more about finding your membrane see the video Reverse Osmosis Membrane Identification. Choose from the following standard membranes: TROM-18-WF, 18 (gpd). 1.8" x 11.8" TROM-24-WF 24 (gpd), 1.8" x 11.8" TROM-36-WF 36 (gpd), 1.8" x 11.8” TROM-50-WF 50(gpd), 1.8" x 11.8" TROM-75-WF 75 (gpd), 1.8" x 11.8" TROM-100-WF 100 (gpd), 1.8" x 11.8"
Stage 5: Measure the diameter of the water line to find the correct filter. (Hold a ruler over the width of the water line to get the diameter.) Choose from the 2 types of fittings, quick connect or female pipe thread fittings. Quick Connect Fitting (QCF): Built in fittings. Simply push the clean cut water line directly into both ends of filter. K2333-JJ Water Filter 1/4" Quick Connect Fitting K2333-KK Water Filter 3/8" Quick Connect Fitting. Female Pipe Thread Fitting (FPT): You must have male pipe thread fittings on your water line to use these filters. To use, screw the end of the filter onto the male fitting currently on your water line. If you don't have fittings on your water line, choose the Quick Connect Fitting Filter above.
