Product review (4 stars): GeneralAire 990-13 Humidifier Pads
Very reasonably priced and both pads were packaged in seperate bags.  I did notice the blue power that others had mentioned. I washed the humidifier pad with tap water and all of the blue power flushed out fairly easily - not sure why pads are packaged with excessive loose blue power in them?? After a season's use, I will have a better ideal of the true value of the pads.
