I bought a used BRS 6 stage RO/DI system in June 2018.
I bought a BRS 6 stage replacement filter kit around xmas, it's still in the bag.
Just dawned on me that kit doesn't come with membranes, my system has 2 membranes.
So from what I have gathered through search feature here on R2R I've found...
The following is an answer to one of our customers who asked, How many gallons will my membranes last. So I thought I would post the answer.
Ahh, There is no direct answer to your question. There are several factors that determine membrane life.
Chlorine will destroy a membrane in no time...
