Product review (1 stars): These Filters Stink - Literally!
I ordered a half-dozen of these filters at the beginning of the year, and just got to the point where I needed to start using them, as I just ran out of the last half-dozen I ordered here.  The first batch worked great, although they didn't last very long (compared to the original Holmes filters).  This batch though, is terrible.  They emit the most God-awful smell when the humidifier is running that we can't even use them.  It smells like the filter is burning, and the stench permeates the whole upstairs!  I opened all six and they ALL smell this way.  I'm hoping Amazon will let us exchange these "stinkers" for the type we ordered last time.  Based on my experience, I'd steer clear of these, unless your sense of smell is completely shot.
