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.

Yes I am handy but not an expert in anything. First off, the packaging is quite nice. Everything is separated according to their install role. The instructions could not be more clear and helpful with hints to help as well. I had to modify which is a nice term for cut away the back wall of my cabinet to get the first shut off valve that connects to your water line only because my line coming out of the wall was short. I think this is the first time I have done a plumbing project and had no leaks and believe me with all those push connectors I was awaiting geyserville... but not a drop. You will need 2 people for this due to the short size of the tubing that is under a bit of pressure, a bucket and a hand on the shut off valve. Over all my reduction is as: City water measured with a TDS meter was 198ppm and with the new RO system it was 6-9 ppm. I would say a very significant drop in garbage in the water. Positive remarks so far. I will keep testing the TDS to see how long the numbers stay under 10. Have fun, I did.
