Membrane costs

The costs of  membranes are more transparent nowadays with more membrane manufacturers competing in the market .  It's hard to believe that the manufacturers didn't want to give membrane quotations to some small contractors decades ago.

RO membrane elements are easily available in online store Amazon.com.  A small home RO membrane costs only  $26. A Dow 4"×40" Filmtec TW30 membrane element costs about  $230.

A Hydranautics CPA5-LD 8"x40" membrane element costs $654 for bulk order in bigbrandwater.com. The cost of unit square meter membrane is less than $16.
