What is the Difference between TFC and CTA membranes?

TFC membranes are bacteria resistant and it has a higher removal rate of total dissolved solids compared to CTA membranes. We strongly recommend using TFC membrane for purifying drinking water.

CTA membranes need chlorine to protect itself from damaging molds and bacteria. CTA membranes should only be used in applications where water is chlorinated. We do not recommend using CTA membranes filtering water sources that are non-chlorinated (wells).
