    Great quality filter
    The installation wasn’t quite as simple as we thought it might be, but it was still simple enough that we could figure it out with little experience in this field. We had to do a little trial and error with the plumbers tape in order to get a tight seal, but that was the hardest part. Everything else was pretty straightforward. Our water has a noticeably better taste and there are no floaties in our water. We are glad we purchased this!

    4.0 out of 5 stars Water in a Well We’ll See
    Reviewed in the United States on September 28, 2023
    It’s pretty straightforward to install this kit. I had to drill a hole in my counter top for the water tap. I like the slim size and the sleek look of the unit. It easily fits underneath my sink. Would have liked to have seen some better water lines/tubing. These plastic semi rigid lines included could be stainless steel braided. I can see them getting kinked or pinched later while under sink items get moved around. I’m also a little skeptical about the quick disconnect style of installing these water lines, maybe because I’m old school.
    But…the water tastes clean and most of all, my wife is happy with it. I’ll update if there are any changes.
