When paired with a KOHLER Aquifer 4-in-1 beverage faucet, the Aquifer 4-in-1 compact undercounter system will provide you with ambient, chilled, near boiling, and sparkling water at the touch of a button. Using a single-stage filtration and absorption system, this undercounter beverage system reduces chlorine taste and odor for a fresh-tasting drink no matter the temperature. And not only does the Aquifer 4-in-1 system bring convenience to your kitchen, it also eliminates the waste of single-use water bottles and cuts down on appliances cluttering your countertop as it delivers all these functions in one system.
[This review was collected as part of a promotion.] The Kohler Aquifer 4-in-1 beverage system is absolutely amazing! In addition to filtering my water, it provides customizable temperature cold and near-boiling water (and every temperatures in between ) as well as carbonated water all in one convenient faucet. It is easy to install and quiet to run - it took me about an hour to install as a novice. Some of that time was spent emptying stuff from under my bar sink. I have nothing but good things to say about this system except for its size. For what it does, I’m not sure it could be smaller. However, it is LARGE. Because of my plumbing and the presence of a garbage disposal, getting this system in my cabinet took some doing and didn’t leave a lot of room for much else. I’d love for it to be smaller. I also think it would be nice for it to come with a CO2 bottle. Needing to buy additional pieces for such an expensive system lessens the luxury experience this system otherwise imparts. I’d recommend this to anyone for their home, particularly heavy seltzer drinkers like us. I also like being able to custom set the temperature of warm water to make bottles for my baby.. Stephanieg.
