I've long rulled out RO filters on grounds of cost, but I just stumbled across these
http://www.vyair.com/scripts/prodView.asp?idProduct=54
and at only £46 I'm tempted.
BUT is there any good reason to go for something more expensive?
And I haven't really found anywhere that explains how to use one.
So am I right in thinking that you have 3 pipes: one supply pipe, one filtered output and one waste output, with about half of the water that goes into the filter ending up as waste water?
IIRC I read ages ago that you have to have to keep the filter wet, or something like that? Is that wrong, or does it mater if you only need to produce 50L once a week and the filter is disconnected and sat in a cupboard for the rest of the time?
