Discard the last 20% of water and the issue is slight but just using a higher pressure pump will give you much better efficiencies even without recirculation.Quote:

The other thing to consider with filter life is the input water. Not sure what you're tap water readings are but I get an EC of 0.4 out the tap in Leicester, in London it was 0.8 and in Sterling Scotland we were getting an ec of 0 out the tap!
So a filter in London is not going to last as long as one in Leicester and in Sterling it'll probably last for years.
Cost is only one part of the equation of course and even if it cost the same as buying distilled water there's inherent value in being able to process at home and you're water is probably purer then bought water which has sat in plastic leeching for god knows how long.
We were using RO for hydroponics and Aquaponics so plastic leeching was more of an issue for us for most users it's a non issue.
