Stokk T1 UV Countertop Reverse Osmosis Water Filter, Carafe Alkaline Boost, 6-Stage RO Filtration System, Reduce TDS PFAS, Large Size (Gray)

I'm impressed by Stokk's countertop machine. It works great. To me, it is much easier to set up and maintain compared to traditional reverse osmosis systems, because this countertop unit does not need any plumbing. It is also much easier to change the filters. There is no after-taste. There is no plastic taste. Another person wrote a review saying that the internal tank of this machine gives the water a plastic taste after it sits overnight, but this is NOT true. I tested this myself multiple times. There IS a temporary taste right after you change the filter, but if you flush the machine a full 6 times, then that takes care of it. That reviewer probably tasted the water without flushing it enough.I personally find that it needs to be flushed 8 full times after the filter is changed, and that's when there is finally no after-taste. Also, I have to point out that reverse osmosis water is quite "empty". In that sense, reverse osmosis water in general has a different taste if you are not used to it. So, it can take a day or two in order to get used to the pure taste of the water.It comes with a 1-liter pitcher. When you press the "pitcher" button, it will automatically fill the pitcher to 1-liter, and then stops by itself. This takes about one minutes. While it does that, you can do other things that you would normally be doing in your kitchen. I do that multiple times in order to fill a 1-gallon jug that I have.The machine can ouput 4 liters of water (just over a gallon) before it needs to be re-filled. To do that, you first remove the plastic lid, which just rests on the back. Then you grab the internal handle within the water container. You first pull horizontally, backwards about two or three inches, which pops it off. Then you pull straight up, and it lifts out of the machine. Then, place it into the sink, tilt it slightly, and fill it with the faucet until it reaches the line marked on the side.The machine is a little taller than I expected, and doesn't fit under my kitchen cabinets, but I ended up finding a spot for it. It is 16.25 inches tall, but you also want a bit extra clearance since you need to move the machine every time you have to change the water container at the back of it, which will usually be once per day.Afterwards, you put the container back into the machine, in the exact reverse order that you took it out. First, tilt it a little bit, in the same way it was before. Lower it down. After it makes contact with the base, now just push it forward horizontally, while making sure that the two "connectors" on the side are properly aligned. After it is fully pushed forward, put the plastic cap back on, which just keeps dust out. Right away, the machine starts automatically pumping the internal tank with filtered water.Personally, I don't use the mineral filter that it comes with. I just get gallon jugs of spring water from the store, and I add about 1/8 of a gallon into each gallon of reverse-osmosis water that I put into my gallon jug. That adds enough natural minerals into it.I've been using this machine for three weeks now, and everything is working perfectly. If that ever changes, I'll make an update here. So if I never update this, then it is still working great. So, give this unit a try. You can always return it for free if you don't like it, which is why I decided to try it. I'm glad I did.

Why did you pick this product vs others?:I've had this item for almost a year, and it has reliably produced great tasting water, and I've had assurance knowing that my drinking water is clean and safe. I wanted reverse osmosis for the fluoride removal and I have not been disappointed. Compared to other water filters, I think I got a great deal and a great filter system with Stokk. Aaron in customer service is also great answering the silly questions that I have come up with!

Why did you pick this product vs others?:I am required to send in water samples to the state, and the samples came back positive for Coliform. When I contacted the company, they actually had no idea how to respond to me because no one has actually conducted a water sample from their system.This product does not actually filter the water as stated. I haven't sent in a water test to check to see what else is NOT filtered out. When contacting the company they told me it was my fault, and that the water sample bottle must have been contaminated. I was sent information about their testing, all testing is done in China. They will not work with me as far as replacing this product in case I got a faulty system. Nor will they refund money if not replacing the system. This product does NOT ACTUALLY WORK! They make you believe it is properly filtering the water, but water tests say otherwise. I would suggest you find a different product, and definitely a different company!

Why did you pick this product vs others?:We wanted to stop buying plastic water bottles, so we decided to invest in a countertop reverse osmosis water filter—and I’m so glad we did.This system checked all the boxes. The water tastes incredibly clean and crisp—honestly way better than bottled. Even our guests have commented on how great our water tastes!It’s easy to use, has worked flawlessly, and feels like such a smart, sustainable choice. My only regret is not getting one sooner!

Overall, I like the product, but BEWARE I bought two units and the instruction manuals were different. I bought the replacement unit because the first one, bought a few months ago, would not work. I assumed that it was beyond repair. However, after reading the instruction manual that came with the SECOND UNIT it added a comment that said to remove and reinstall the RO filter if it will not pump. Notably, this small comment was MISSING from the manual that accompanied the first unit. Now I have two units and they both work. Notably, the system is prone to air binding, which is not too difficult to fix. After I had the same issue with the second unit, Stokk sent me an email that provided instructions to remove the air binding problem.The below is a part of their email:The following reasons may be the cause of E1 error:1. Continuous water filtration protection. Please long press the Faucet button to empty the pure water tank, plug in the power again after 3 minutes of power outage, and exit the protection mode.2. There is air in the machine pipeline, resulting in slow water filtration. Please take out 3 filters and let them stand for 2 minutes before reinstalling.3. The spring at the base of the unit is scaled and cannot rebound. Please clean the scale and try to press the spring repeatedly to make it rebound freely.4. The water tank is not installed in place. Press the water tank firmly to fit it completely.5. The loss of the float causes the water level sensor to fail. Check that the float and rubber plug in the water tank are still in place.6. The water tank filter is clogged. Please clean the filter and reinstall it.So, yes, I like the two units now adorning my kitchen. It was a strange process finding out how to clear the air binding problem, but I hope it was worth it going forward. Other than this issue, the system works fine and the water seems very pure. The overall quality of the unit is good (fit and finish).
