Product review (3 stars): You have no choice :)
This product is a defamer to Honeywell's line of quality products. This filter for some reason is catching up fungus very fast. The original filter that came with the humidifier was very good. It lasted two winters with good care but this, hmmm doesn't last even one whole season. Disappointed but you have no choice... you don't get competitive X brand products; others are even worse.
