About this item
- ROG400 is a tankless reverse osmosis system. The vertical filter placement design saves more than 30% of space under the sink compares to a horizontal design. A leak-free integrated water route and filter change indicator.
- The PAC filter is a combination of two sediment filters and a carbon filter that removes sand, rust, chlorine, odor, and smell. The RO membrane removes up to 99% of over 1,000 contaminants, including PFAS, lead, fluoride, arsenic, asbestos, and more for up to 3 years. The AC or the active carbon filter made from coconut shell further polishes water removing odor and bad taste.
- With a built-in water pump and GE reverse osmosis membrane rated at 400 GPD, the water flow rate from ROG400 is at 0. 3-0. 4 gal./min., with a pure to wastewater ratio (up to 1.5 : 1).
- DIY installation and future filter replacement. The unit can be connected to the ice maker/refrigerator. It includes an artisan-style stainless steel drinking water faucet.
- At GreatWell, we only use quality components tested by an independent 3rd party against NSF/ANSI standards. Lifetime technical support provided by our dedicated support team based in Atlanta, GA.

Very good price affordable shippin garrived quickly comes with booster pump has a pressure gaugewater quality appears very goodnot really a whole house filter RO system more like a really big fountain setup install manual was all but useless, was generic & for smaller systemyou need to add a pressure tank all hook ups and fittings were 1/4 inch plastic making it difficult to adapt to household plumping1/4 inch lines restrict water flowI have a farm with a well, water is good except I have about 2500 ppm dissolved solids and need a RO system to remove them. I managed to adapt this to provide water to kitchen and hot water. I added a large pressure tank and a booster pump. The RO put out about 34psi on its own, not enough to have a decent shower, as flow drops. I added a 20gal pressure tank to act as a reservoir. and a booster pump. The dissolved solids is a fancy was of saying salt. This was corroding the plumping pipes and fixtures. It was also destroying hot water tanks.
