Membrane, 36 GPD TFC RO reverse osmosis membrane - standard size 1.75" X 11.75"
Standard size membrane can be used as a replacement for most TFC model Reverse Osmosis.As of December 2019, these are no longer used or carried,
We recommend using the 50 GPD membrane as a replacement,
see here: PN 24TFC50
This TFC Membrane works on Well or City water supplies.
If you are on chlorinated "city" water, you should use a Carbon Block Prefilter ( like our CTO 2 - 5 Micron 10" Carbon Block ).
This size membrane is used in the Water Shield brand RO distributed through Water Treatment Warehouse, Venice, FL.
All models installed before June 2018 ( after that, the 50 GPD membrane might be used ).
