My recommendation is to go to E-bay and buy the 100 gpd unit from Aqua-Safe Systems. I use it and so do many others on TR. At $99 plus shipping I rate it a "Best Buy" in
RO/DI units.
It doesn't matter that you only have a Nano. the price difference from 100 gpd to 50 gpd is minimal. You are going to be making water intermittently, why wait longer than necessary.
