Chlorine will destroy a TFC membrane unless it has an additional filter to remove the chlorine before reaching the membrane. In a 3 stage unit like this, a TFC membrane (which has a higher rejection rate of many impurities) can only be used in non-chlorinated water.]NSF certification on the TFC membrane unit, system tested and certified to ANSI/NSF standard 58.
