Review: quit hauling water home and get this. Helping us all replace that horrible plastic bottle waste - Very good water machine when properly maintained and filters changed. Got 3 years out of my first machine but was starting to have error issues and not pumping very well. Got a new one a month ago and it works perfect and dispenses quick again. Tastes great. Ice it makes is very clear Great for fish tank water replacement also
Review: Excellent unit! - We just got this hooked up and so far it seems amazing! Was really easy to setup and get started. Changing out the filter also is a very simple process. It holds a lot of water, which is great. The water comes out pretty quick compared to other filtering units. We have a jug we fill up and then put in fridge for cold water. The hot water feature on this is incredible, comes out immediately without having to wait for the temperature to change. Hot enough for a cup of tea. Water is crystal clear and tastes great. For anyone living in an area where you can not put one under the sink, this is a great option. Also, looks very stylish and clean on the counter.

*by J***G on November 13, 2025*

I really wanted to like this countertop instant hot water purifier, and while I do enjoy some parts of it, there are definitely things that could be improved. First, the manual is a little confusing, so it took some time to figure everything out. Also, you need to refill and empty the water very frequently, which is inconvenient because the fresh-water tank and the wastewater tank are built together. Another issue is the water tank design: the level markings don’t make sense. It’s actually impossible to fill the tank up to the “max” line because the internal divider sits around the 2/3 height of the tank — so the top part isn’t fully usable at all. The machine is also quite heavy, so it’s not something you can easily move. That said, I do love the heating function. It gives you the exact temperature you want in just seconds, which is super handy for tea, coffee, and baby bottles. Overall, I’d still recommend it — but only if it’s on sale, considering the design flaws.
