RO/DI Question

[brewercm]

I'm looking at getting one in the next week and was looking at either a 75GPD or 110GPD unit. The price difference is about $25.

Question is since they both use the same size filter cartridge are they both good for about the same "total amount" of water before cartridges need replacement. If the GPD difference is the only issue the 75 should be fine for what I need.

Go with the 110.

Go with the 110, I settled with the 75 and run out of water on mix day! It takes forever to get 32 Gallons! Plus my family drinks the RO water too. It was the best thing I ever bought for the tank. Mine keeps 5Gal in a storage tank for quick use.
