Product review (1 stars): Lousy product & worse customer service - BUYER BEWARE
I ordered three of this item,  Since the seller advertised this item as a 3-pack of filters, I presumed I would 9 filters.  I received 3 physical filters.  In addition, they were shipped in a plastic pouch and arrived at my home in terrible shape.  Only one of the filters was usable.  When I inserted the filter into the humidifer and added water, the filter portion of the filter litterally started to peal off the wire mesh inside the filter to keep its shape.

I contacted the seller and they indicated they would correct the order and ship the remainding filters.  That was weeks ago...nothing shipped and no further contact from the shipper.
