Review: Great water filter
Review: All Stainless with a Carbon filter is exactly what I wanted. I really like this product. Had it for a month so far. The only way this can leak is from over or under tighting the valve nut, Over filling the top tank or leaving the valve open which I did by mistake,lol be careful. Half the price of some. It came missing the stand. I just made one and works good.

**Q: How long does it take to filter the water?**
A: from the time I add city water to the upper chamber I'd say it's completed within 30 45 min.  Be aware there's still about an inch of water left in the bottom of the upper unit.  The bottom of the filter sticks up that high.

**Q: What is the water filter’s height? Is it suitable for use in the kitchen?**
A: Approx 20” high for the filter unit and with stand approx 26”.  Soda can for size

**Q: Where do we informtaion on what this filter does/does not remove in our water?**
A: I was not able to find anything on this issue for waterdrop filters
