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.

Item was pretty easy to set up and get running, right size for me to fill water tank without difficulty (65+ senior here, no longer a spring chicken). I LOVE IT. My town started chlorinating last fall, and you can smell it coming out of the faucet - chlorinated water is bad for aquariums and house plants, and I suspect not healthy to drink. I had a different filtering system but wasn't sure how efficient it was; I had a water distiller, but it ran 3 hours at 600 watts to get 1 gallon daily. This RO system... is brilliant! I'm happy to drink water again, and even my 2 old dogs are drinking more water since I got this. It's a blessing to be able to drink clean water again at a price I could afford - thank you, Stokkers!

I really wanted this water filter to work, but it ended up a complete nightmare. We purchased it end of August 2024 and since two months it constantly showing the E1 error - regularly multiple times a day. Every time that happens, I have to unplug the unit, drain the water, and reset it. On top of that, it started leaking for a few times now water from the bottom, which is a major safety concern sitting on a kitchen counter next to electrical outlets.Manual: The manual gives no clear instructions.Customer Support: The customer support "tried" to help, however the response time of the customer support is very very slow and no clear answers are provided. They offered to sent us a replacement unit, however without a water tank. After asking multiple times follow up questions, the customer support gets radio silence and is no solution provided after 3 weeks. I already wasted too much time trying to troubleshoot something that should "just work".The product looks sleek, if it works water is tasty, but with the quality of customer support (with a one year warranty) it really destroys the experience when issues occur after this short amount of time.Stokk really needs to step up their quality control and customer support.

I purchased this item a year ago. A year later when I changed left side filter canister it was stuck on and wouldn’t twist off. After a couple emails to the Stokk company a free replacement was on its way to me. With the new free one working fine, my daughter twisted again with the old filter and my daughter was able to twist off the stuck left canister. So I gave it to my daughter to use. Then, I emailed the Stokk company to charge me for the new one. This polite representative Ann, emailed me back to just keep it, free. I’m impressed, very impressed. I thought it would end as another hard lesson but with the help of Ann, my daughter and I are very satisfied customers.
