Product review (2 stars): Not a Holmes product
After reading many of the reviews on this product before purchasing, I realized that I might not get a product actually manufactured by Holmes. As you can see by the Customer Photos I submitted, the filter was not manufactured by Holmes but fits my model Holmes humidifier. I cannot yet comment on how long the filter lasts as I just received it, but I also find that filter life fluctuates greatly with weather, use and care/cleaning of a humidifier.
