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.

$17 every 6-8 weeks for average faucet filter that doesn't even remove the same minerals/chemicals. Having a reliable ro system gives me the quality of drinking water I'm looking for!

We have well water with odor and taste issues, so we were purchasing water in 5 gallon jugs prior to installing this RO. Install was not complicated.

Having moved from NY state with excellent public water to NJ state we felt for more than a year that something must be done. The water tastes much better with this system than with our old system.

After installing this purifier and testing the purified water, it was down to 5 PPM! This is the cleanest and purest water I have ever tasted. It honestly has a sweet taste to it!
