Product review (5 stars): Accordian style works the best!!!
I received the product and what I received is the accordion style product.  This style product is the more expensive type and works best in the  Emerson Humidifier.  The honey comb style seems to just fill up and not work as well at all.  The machine just runs and runs and runs.  the accordion style really puts the moisture in the air.  Which is what you want.  So spend a little more and get the best.  Keep a spare set on hand too.
