any water experts here know how these new units that have crazy high GPD membranes 400-600GPD and are able to do 2 cups of clean to 1 cup of brine?

I have this one. Super nice if you have the power supply. Independently verified with my own meter down to 10-13 ppm as long as you purge it for a couple seconds before collecting water.

I have very hard (municipal too) water at my house. I've a softener at the front end of the inbound water line and off of that I have my 4 stage RO system which is hooked up to a 20 gallon tank. I've also got an Aquatec 6800 to increase throughput and pressure because I've 3 different outputs for the RO. One line feeds the kitchen sink RO tap. One line feeds the water/ice on the fridge. One line feeds the whole house humidifier hooked up to the air handler in the basement. Running our softened water to the humidifier resulted with the pad lasting like a week before it was riddled with scale.

This system works very well. I even fill up our (3) room humidifiers to supplement things to help reduce dryness while we sleep.

I can't imagine 600GPD throughput on this unit is remotely accurate but am curious to hear some firsthand accounts.

So is this a good deal or no?

Another question that I would have is whether having only one carbon pre(or is it post?) filter is sufficient? Surely it would have to be apre filter to keep chloramine/chlorines off the membrane filter?

It is because they use pump to pressurize water in RO module.
Once pressurized to 80-150 psi (tap water pressure is just 40 psi), water flux improves by 4-8 times and less brine rejection but concentrated.

Industrial RO operates more than 500 psi.

Thanks, never noticed that before. Now it makes some sense at least. Still not sure how the ratio is so high on these though compared to standard ro

How do these compare to the 6 stage RO systems? I'm considering one of those which puts minerals back into the water.

Is the point of this to not need a tank? If you search Amazon for RO system you'll see the 5/6 stage units that use standard filters which are reasonably priced. I've had a 6 stage iSpring unit for over 5 years and it's been great. Looks like their filter costs have gone down a lot so it's more in line with the multi stage units. 2 years of filter for this is $140. 2 years of a 6 stage unit is $133. The 6 stage also adds minerals back.
