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.

Excellent purchase. A little over a year ago I purchased this Reverse Osmosis Drinking Water Filter System which my plumber installed. The most important reasons for me in choosing this system were whether I would be able to enjoy and safely drink my tap water. I live in Phoenix AZ where untreated tap water is generally unpalatable with taste, odor and impurity issues. And because of environmental concerns I did not want to endlessly be purchasing water in plastic bottles. After much research and reading reviews of other filtration systems I selected this system because of its many positive reviews, and because it best fitted my needs. My water tastes great, ice cubes are crystal clear, no scale build up on dishes, glasses, coffee tastes great and I drink more water now. I only water my plants with filtered water and they are doing fantastically. I love the design of the faucet which complemented my kitchen faucet perfectly, however the one provided was stainless steel and my kitchen is fitted in chrome. I called the company and a replacement faucet in chrome was immediately sent to me. I am very impressed with the customer service and the quality of both the system and faucet. I have experienced no problems, leaks or water pressure issues. I am completely satisfied with the system overall and the quality and taste of my water. I am quite happy with this purchase and highly recommend the product.
