The best, Spectrapure without a doubt. No one hand tests and guarantees their membrane 98+% efficient ike they do. A 2% increase in membrane efficiency doubles the life of your DI resin so you can see how the cost difference pays for itself in the long run. Usually in less than 2 years of normal use and as short as a year in heavy use. I use a dual membrane piggyback MaxCap RO/DI system and love it.
