Product review (5 stars): Worth The Money
I was a little skeptical at first. I purchased this product because I was reading the reviews on the traditional filter used for a Honeywell whole house humidifier and someone mentioned this product. I now see why it has so many positive reviews. The traditional Honeywell pad always had mold and mildew in the plastic, three sided cartridge holder for the filter when I changed it, and I always had to soak it in bleach to get all of it off. I just changed the new filter with silver in it. WOW. no mold or mildew anywhere. NONE. Clearly this filter is doing exactly what is made to do, which is "filter"  healthy water into the furnace. I would recommend this filter to anyone.......
