Product review (3 stars): Not impressed
These filters got moldy/dirty in less than one month, whereas the original filter that came with the humidifier lasted between 2-3 months. We have a Vicks V3700 humidifier, listed as compatible with this product, but it was difficult to fit the filter and I had to bend the metal wires to get the lid to close. I was not impressed with the quality or durability of these filters.
