Just what I needed

I was looking for a countertop water filter for a long time, and I am so glad I decided to purchase the NU Aqua. Definitely having a hot water option is a huge plus since I drink a lot of tea too. It is also very helpful when having people over because they love to refill their water and teas by themselves! It looks nice too. I love it.

Perfect Countertop RO System

After getting fed up with Waterdrop Countertop RO system, I was recommended the NU Aqua one, and I am glad the water tank is enclosed, no more accidentally knocking a half tank over and spill the water all over the counter.

The hot water is a very nice additional, although I do wish there is a 212F (100C) option, but 200F would do.

I love a counter top reversed osmosis system

I love this system for the convenience and also it produce hot water immediately which I loved. However I wish the water tank is bigger, less noisy, and I don't have to throw away the water when refilling, I found it wasteful. Other than that, it was great, it produced such a great tasting water!

Good product

It looks like it does its job well
