Product review (4 stars): Good filter, good shipping, still a reasonable price.
OEM qualty with mildew control that the cheaper white filtters do not have. Fit my Honeywell humidifier perfectly and last all season. Can be rinsed clean (of the filtered dust) and reused. It's getting harder to find these filters... and the price reflects that. (Used to be able get these for around half the price available now, but still worth the price.) Supplier filled & shipped the order quickly and delivery was fast.
