Great Machine

This water filtration machine is awesome. Great machine for people who don’t want to install the filter system under the sink. It’s also nice because of the instant hot water feature if you’re a tea drinker.

Simple and sleek

This machine was exactly what we were looking for. It fits in our apartment size space. The water taste delicious. It’s simple to operate. I really couldn’t have asked for anything better. We’ve only had it for about three weeks but it has really fulfilled everything that we want it. We are a couple of two that work from home so we use a decent amount of water maybe not as much as, a family of four might and we refill the tank twice a day however, it’s very simple

Caroline Wang

Water quality is great, easy to use and it's also very beautiful!
Only wish the temperature could be shown in Celsius too and had hotter temperature setting.


Finally a reverse osmosis system that comes with instant heated water. thus functionality is common place in elsewhere in the world but the US for some reason so I’m glad someone finally included a heating element in their countertop water filter system.

On screen tds readings, filter life are useful features to have.

The machine is a little larger than I expected but not a dealbreaker.
