At the moment they have lasted 2 months in the water with no sulfur smell. This is a new review. The fliter lasted 3 months, which is what I expected. The smell in my hot water tank returned when 3 months had passed. I am satisfied that I have been using this filter for 3 months, the paper filter only lasted a month. After replacing the filter, the smell is gone. Ok, new review. This time I drained the water heater, replaced the filter after 5 months and I have a ton of iron in my well. This is the best filter on the market. My water has never been so clean and odorless in 25 years. I've stocked them up in case the price goes up.
