Product review (5 stars): RJ from Michigan
I have had the GeneralAire humidifier for 6 years.  The other 990-13 evaporator pads that I have purchased cost close to twice as much per pad as the 2 pack including shipping.  The powder is on every pad that I have used.  Rinsing the pad with water washes off the extra powder and makes it easier to handle without making a mess.  Good quality and great price.
