Rated 4 out of 5
from need instructions there should be instructions as to when to clean filters and more importantly whether the loose plastic balls should ever be washed. This unit replaced an identical unit which I used for >5 years until the filters fell apart, and the container filled with water which failed to come out of the proper lower spout.
