RO filter replacement
This is exactly what is described and works great in the water drop system we have. Easy to install yourself!

Great filter love it
I’m on a well and have this filter on a kitchen sink for coffee and drinking water. This filter is very simple to replace and most importantly takes the hardness down to almost nothing. I test this water often and it’s consistent.

Easy RO System!!!
This filter is so easy... all you do when the new one comes in is twist out the old one and twist in the new one. You do have to reset your machine though so the light goes back to blue. If it doesn't go blue then it hasnt been reset yet. So you push the reset button at the top and hold it down until it beeps then immediately push the filter light you are changing.. if you are doing both then do one right after the other with no pause between pushing the buttons. Once they are blue its reset. I had a hard time with it and contacted their customer service and they helped me through email it was very easy. ... show more

Great tasting but dispenses slow.
I love everything about this RO system - it’s under the sink out of sight, it’s quiet, and most importantly the water tastes really good. Like really good. My only gripe is that it dispenses so slow. Not sure if it’s the filter, the system or what. But all I know is that when I first bought it, it dispensed faster. ... show more
