Reverse Osmosis Systems are Wasteful

I have always heard that reverse osmosis water purification systems are wasteful, but I had no idea how wasteful they really were until today.
I work with a network marketing company that sells water filters among other things, so I decided to do some research to put together a free report about how to pick the right water filter for your home. Of course, I’m hoping that when I’m done all of the evidence will say you should buy mine, but I’m trying to keep an open mind about what I find.
The report isn’t finished yet but I had to share what I found out about how wasteful reverse osmosis systems are. And that is that household systems are only 5-15% efficient. That means that up to 95% of the water going into the system goes straight down the drain. If you get 5 gallons of water from a household reverse osmosis system, you may have flushed from 40 to 90 gallons of water down the drain. I was absolutely astounded.
Fortunately, industrial systems, which have higher pressures, are closer to 48% efficient, which is still terrible, but at least they get almost half of the water to use.

My filter is nearly 100% efficient. Sometimes I spill. 
UPDATE: The water filtration report is finished and you can find it here.
