Product review (2 stars): The filter does a great job of eliminating the sulfur odor from my well - Update
The filter does a great job of eliminating the sulfur odor from my well. I only wish it lasted a little longer.  I have to change it about every month.

UPDATE:  I just ordered another of these filters and installed it about three days ago.  It is doing nothing for the sulfur smell, Don't know if it's a bad filter or a damaged one.  Not satisfied at all.
