## Description

6-Stage Dual output RO DI water system for both drinking water and Aquarium use. Comes complete with pressure tank and dispensing faucet and 2nd output for Aquarium. Made in USA Koolermax Brand, Brand New, 120 GPD (gallons per day) production capacity.

Review: Good RO/DI unit - We love this unit. It works and clean up the water pretty good. We have high TDS coming into the house 500-550 and it will reduce the TDS to about 20-25 before the DI resin. The high TDS does make it burn through DI resin pretty fast but that is not the units fault. I will say that a universal filter will not fit this unit and you have to buy them from koolermax but they are good filters and cheaper than most to buy.
Review: Working well so far - Bought this a couple weeks ago and the system has been working well. Instructions for installation was clear. We were missing one of the shut off valves. Contacted sellers on desertcart and the missing piece was shipped promptly. Can't complain.
