How to choose the correct RO membrane filter for your RO system?

You need to have a standard size RO system with standard membrane housing (look at photo)
Check the capacity of your RO system or RO membrane. Capacity means how fast the membrane produces water. The number means gallons per day (GPD). You can find this from your RO system owner’s manual, and specifications.
You can also find the GPD rating from the membrane filter label when you take out the membrane filter.
You can also find the GPD rating from the drain flow rate or from the flow restrictor that is connected to the drain line.

Flow restrictor size (drain rate) 200 mL/min. uses TFC-24 membrane

Flow restrictor size (drain rate) 300 mL/min. uses TFC-36 membrane

Flow restrictor size (drain rate) 420 mL/min. uses TFC-50 membrane

Flow restrictor size (drain rate) 500 mL/min. uses TFC-75 membrane

Flow restrictor size (drain rate) 500 to 600 mL/min. uses TFC-100 membrane

Flow restrictor size (drain rate) 800 to 850 mL/min. uses TFC-150 membrane
