Product review (1 stars): Clogged drain tube and caused major damage to furnace and flooring
I recently purchased and installed this without any issues in my humidifier.  Everything was great, or so I thought.....  I arrived home to find water dripping from the ceiling in my kitchen.  Come to find out my humidifier which is mounted on the furnace on the 2nd floor above the kitchen was having issues.  The pad was disintegrating and had clogged the drain tube.  This caused the unit to drip water down into my furnace.  Ultimately it cost me over $2500.00 in furnace repairs and hours of time cleaning up the water mess.  Beware!
