I got this RO/DI about a year ago:
http://filterdirect.com/product_info.php?cPath=21&products_id=29
I'm starting to get a bit of TDS in my RO/DI, 9 to be exact. Should I replace my filters? What do I need to replace? I hear a lot of people talk about the membrane, but I've never taken it apart to know which piece it actually is. Does that need replacement? I see that its the most expensive part...
any other places I can order replacement filters for cheap? BRS?
