Great system. Was buying bottled water before but even some bottled water tasted off. I don't have that issue with the waterdrop RO. Water tastes great.
There appears to be a slight difference in the labeling of the filters. The manual on my filter unit says to use a filter XYZ. (I don't know what that number is.) When I searched online to find that filter, it was called something else. I had to dig in a little deeper to make sure it was the right product before pressing the purchase button.
