- Waterdrop K19-H Instant Hot Countertop RO System, No Installation Required | 6 Stage RO Filtration, NSF/ANSI 372 Certified, 3:1 Pure to Drain, 4 Temperature Options, Countertop Reverse Osmosis System

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!

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

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.

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.

Used it for only 1.5 years. It had problems on and off throughout, but always came through at the end - until today. The E04 error code came on and I routinely did the appropriate troubleshooting procedures for it. Afterwards the machine was stuck in "flush" and kept flushing and making loud noises. After several (10x and more) times to reset the machine, it just kept flushing and flushing and the machine is absolutely unusable. Nothing lasts forever but did not expect it to last this short of a time. Highly disappointed.

I've owned this for almost 2 years and I have changed the filter once. There is a built-in sensor that tells you when to change, but I also have water testers. The number range from high single digit to the low teens depending on the tester I use. However, I do fill it up to the very top to the "max" line and I believe you're suppose to only fill it to the lower line before it spills over to the other side. Pros: It works! I like the taste of the water and it makes hot water instantly. And filter replacement cost is very reasonable. Cons: The tank is small so you have to refill it constantly. I refill mine 2-3 times a day for a family of 4 people and we're not very thirsty people. It's on your countertop so it takes up space.

I've owned this for a couple of months now and I'm very satisfied. I'm transitioning from a life time of bottled plastic water and this is my first countertop ro. It is easy to set up and use, tastes great, looks cool on the kitchen counter, water quality is supposedly great (better water stored in plastic bottles or whatever yo) also that volume button and temperature control for hot water is super useful. 10/10
