I have a spectrapure ro/di filter but I’m not sure which one I actually have (ratings and whatnot). I’m new to ro, I’ve always just purchased mine from a store. I acquired this one in a tank purchase though. All I can see on it is “aqua-st-kit”. I see it was made in 16 but no other model number. My main concern is finding replacement filters, but also how many gpd does it produce?
