Product review (4 stars): Good product, but not the same as in the past.
This is the second replacement pad HC26E1004 that I have ordered.  Last year, the product was as described by earlier reviewers as a pad within a plastic frame that fit right into the humidifier pad slot.  This year the pad was as pictured in the photo without a frame and without instructions on how to install.  Since the manual for the Honeywell humidifier says to follow replacement instructions on the pad box, I was not sure how to replace the plastic tray top since there was no illustration.  Otherwise, the pad is the right size and fits the old tray, but you need to clean out sediment inside tray before putting in pad.
