## Description

Reverse Osmosis Water Filter

Review: Love the quality, affordability and hot cold options - Love having the assurance of drinking clean water with hot and cold options! I’ve tried Waterdrop product before and appreciate the testings/filter results all products went thru. The only downside is that I wish that the water volume/oz is labelled on both sides of the water reservoir since this is a countertop product. I can’t see the measurement at all when I place it against a wall. See photos. Setup takes about 20-30mins, but it’s straightforward like the instructions provided. Just use 2 big bowls for rotation during flushing. Highly recommend!
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

*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.
