LF RO Membrane

Looking for a decent RO Membrane for a 75GPD RODI Unit. Can a larger GPD Membrane work better?

Match the flow restrictor to the membrane

My unit is 75 GPD so I will have to get a 75 GPD membrane? What happens if I get a higher GPD membrane?

It will produce more water. Make sure it still has a 4:1 ratio by changing the restrictor to match the new membrane.

it’s best to just stick with a 75 GPD Membrane?

You can if you wish but the membrane posted above is pretty much the best one going and the one I always recommend. It's really not much trouble to get a flow restrictor tuned in properly.
