We were able to test the new mes2 membrane from maple expert solutions and I have to say very nice, why would anyone buy anything else. It has a 15,000 daily flow rate compared to 8-12000 like the nf90 and h20 70, with A90+% rejection rate. And the best part it's 550.00$!! Check it out on their website.

We started off with 11.5gpm permeate and a 2.5 gpm concentrate on a 600 gph machine at 425 psi. It rested at 10 and 2 after initial use
