Product review (2 stars): Skuttle Replacement Filter
The filter is very fragile and has a special coating on it to prevent mold since water runs through it.  The wick needed to use the filter was missing, and a lot of the coating was missing, possibly because of how it was shipped.  I was unable to use the product as intended because of the missing wick. Otherwise, the filter is an original replacement pad.  Amazon refunded the price of the product.
