I would use caution calling this a Reverse Osmosis system, with that much output and no tank. It looks like just a bunch of filters nothing more. True systems this size will only produce 1 or 2 gallons per hour, unless your water is very clean to start with. Membranes that can produce 100 gpd are out there but the systems are a lot more expensive. The membranes alone are over $ 100,00
