sounds promising!
I've been asking around and only hearing good things, but I would like to try and find out more about the pre-filter because I have to filter so much. I know that the "Preevolution" filter is the obvious choice, which includes a carbon filter and a sediment filter in two separate chambers and I'm pretty sure I don't need the carbon since I will only be using well water which contains no chloramine (which I think makes the carbon filter unnecessary for me). Perhaps I could switch out the carbon and replace it with another sediment filter? Or maybe just take away the carbon and only use the sediment....
I also heard from someone that buying a separate DI cartridge and putting it in front of the RO unit will also greatly lengthen the life of the RO membranes, but most DI units flow at <1gpm which would make it more difficult for the RO to function at the rate that I would need it to (60 psi).
Not too sure about all this stuff - I am going to inquire with hydrologic and ask around and I'll update here. Any ideas you guys might have is awesome
