Product review (1 stars): Couldn't be more disappointed
I have already had to replace this item after less than 2 months use because it caused my entire house to smell like mold & mildew. My furnace and humidifier are both 1 year old and when the service tech came out a week ago he said the filter was installed correctly. Not only did I waste money on this product but I had to pay for a service call and a new humidifier filter.
