I love the concept and the size of this unit. I am disappointed that I have to fill it so often and that a lot of water is wasted because you have to empty the container each time it says to fill. But, I guess that’s what RO is. The water does taste good! I hope it does what it says and removes the nano plastics . Haven’t had it tested . I would recommend this unit. Much easier than having a system installed under the sink.
