CF01 Countertop Reverse Osmosis Water Filter, 8 Stage Nano RO Water Filtration System, Home Water Purifier, 4:1 Pure to Drain Ratio, No Installation Required, White

This water filtration statem is very efficient. After flushing it for 6 times, the water taste so pure and sweet! No tap water raste, a lot more better that the filtered water you buy from the store. Now i can save a ton of money from buying filtered water. The only downside is you have to flush out the water everyday to he able to have fresh water the follwing day. I wish the replacement filter would be cheaper. But overall, its worth the investment if you want cleaner, fresher taste of water. Will definitely recommend this to anybody that would like a water filter that really works.

I bought this unit about 6 weeks ago. Our tab water fluctuates between 230-250 TDS and I noticed that our carbon fridge filter really didn't put a big dent in that number. On top of that we live near an Air Force Base where a couple of times now they had spills of forever chemicals, so I decided we really needed a good filtration system. The Koviet unit does a very good job and gets the TDS numbers down to 14 to 36, mostly being in the low to mid 20 TDS. The water looks so clear now, I never realized how our tab water wasn't really that clear at all, my husband also noted this big difference in water quality.On top of that, Koviet has really great customer service. I had a question about the fluctuating TDS numbers on the display and they told me that is because it recycles some water and because of that you really have a little less waste water than some other units. I figured out that once the numbers go higher than the twenties on the display I stop running the water and wait for the pump to stop working and then start again and that makes the TDS numbers go really low again, even into single digits.Because we really love this unit I ordered a second one for our daughter. After the initial cleaning the TDS numbers were much higher than our first unit, high fifties and worse, so I called customer service and they immediately sent a replacement unit. As I said, great customer service. I am very thankful to them and only can highly recommend the Koviet reverse osmosis filtration system!

It's good, just that if you drink a lot of water like I do, you have to change the water often. It works great, the size is decent. Not too big not too small. I do however wish the water Holder held more water. Installation was very easy a bit confusing at first but once I figured it out it was easy. The filter quality is great and the water tastes delicious. I love the design and color.

Nice size unit for a countertop, especially if you have overhead cabinets. This fits nicely underneath, and you can still take out the holding tank for refilling, though it's a little awkward. That's why I have the unit only partly under the cabinet and turned sideways for easy access to the tank.Another thing. The instructions tell you how to insert the filter. Make sure the filter is fully inserted and locked into place. I made the mistake of turning the filter towards the 'locked' symbol, but it was really snug and I apparently didn't turn it enough. When I filled the unit and plugged it in, all the water in the tank drained all over the countertop. We have dark counters and I didn't even notice the water until it started dripping down the sides. So just be aware.Also, there is no on/off switch. The unit starts filtering as soon as you plug it in. So you need to follow the instructions and do things in the proper order. Make sure you remove 'all' the protective tape that was put in place by the manufacturer for mailing. Check the unit closely for that. Don't plug it in until you have followed the instructions to insert the filter, fill the exterior tank and put it in place. Then make sure you fill the tank and run it through the filter 4-6 times to clean and prepare the water for human consumption. The LED screen displays numbers on it, but frankly I'm not 100% sure of what they mean. The instructions don't explain it. So I'm glad i bought an inexpensive ($7) handheld water test device to measure water quality. I used that to tell me when I could safely use the filtered water. My tap water TDS was an unhealthy 227 but after completing the initial filtering process and running it through 6 times, the TDS dropped to 10. Anything below 50 is considered safe.I'd like to see the manufacturer include information in the instructions on how to read and understand the display readings. Other than that, I like the unit. It's probably too small for a family, especially if everyone drinks from it. The tank on this holds up to one gallon of tap water. In our house there are only two humans and two pets. We have county water that keeps failing water tests so we've been drinking bottled water for over a decade. We had two prior pets who were drinking the tap water and both died too early from illnesses that could be linked to the water. So rather than give the new pets bottled water we got this water filter. I still prefer the taste of the bottled water over the filtered water, but I hope to learn to drink the filtered water while home and use bottled water when I'm out and about.

Our tap water is disgusting. Consistently measured 600 PPM. The filter gets it down between 20-30. Some other reviewers aren’t impressed with a 20-30PPM filtration—but we sure as heck are! Water tastes amazing. Great value for the money. Hopefully this filter lasts us 12-18 months before needing to replace. Setup was easy. And the fact that it can be placed anywhere is an added bonus! Yes, some words weren’t translated perfectly—but that’s only an issue if you’re really incapable of understanding simple steps. If you understand intent, you shouldn’t have any issues following along.
