Yes. The way most RO filters are designed, they waste a lot of water, because of all the pressure the tank imposes. Specifically, as the tank becomes full, it takes more and more water to go against the backpressure. I use Brondell Circle RO which developed a different design that wastes less water. Much less water. They wrote an interesting white paper about it. You don't have to read the whole thing. Just look at the graph on page 5 to see how efficient this system is: https://www.brondell.com/media/wysiwyg/water-filters/circle-white-paper-final.pdf https://www.brondell.com/media/wysiwyg/water-filters/circle-... It's by far the best designed filter I've ever used. Changing the filters is so simple because of the lack of high water pressure. Previously water would spill everywhere and tightening and loosening the filters was such a nightmare. Like an mini-explosion. It's also less susceptible to structural breakdowns (water will bore through any material over the span of months. It's how my old system failed). Nobody has really innovated on the RO design as well as they have. It stayed stagnant for a number of years and it was something I complained about constantly. For example, one of the other innovations they've done (that most other companies don't automatically do) is automatic flushing so the RO filter last longer. You can install this on old RO systems, but normally, you have to do it manually. Other companies have also tried building a tankless version of the RO system, but the problem they ran into is as the water empties, there's less pressure, so the water dribbles out. Brondell built a flexible reservoir so the pressure always stays constant. It's a beautiful piece of engineering and I wish more people heard about this company. https://www.brondell.com/circle-reverse-osmosis-water-filter-system/ https://www.brondell.com/circle-reverse-osmosis-water-filter...
