Product review (1 stars): Utter Garbage
If you notice the good reviews are ancient. Honeywell should be ashamed to have their name associated with such an inferior product. As others have noticed, years ago these OEM filters had a blue backing. If for no other reason this gave the filter structure as it took on water weight. Then they disappeared and were replaced by a filter without the backing but one that at least kind of go the job done. Now ..... these are pure garbage. If you soak them in a tub, be sure to treat them like a irreplaceable family heirloom, or they will fall apart in your hands, Same goes when trying to flip them over when you refill your tanks. At any price they are overpriced. For me the Honeywell name is forever tarnished and when this humidifier is retired, I will never buy another product with the Honeywell name.
