Product review (1 stars): Item Received has Different Part Number Than Advertised
CAVEAT EMPTOR !!  The original filter that came with my humidifier was a "Permanent" i.e., washable filter, hence the HWF75P part number.  I ordered this filter which is listed on AMAZON as HWF75PDQ-U.  The item that was delivered, was a HWF75 and the package states this filter is only good for up to six weeks.  This is clearly not the filter I thought I ordered.  I will probably keep this and use it until it is spent, only because nobody stocks this filter locally and I need to use the humidifier now.  I will not purchase another.
