Product review (1 stars): Humidifier Pad Flakes Apart After Installation
Do not buy.  The pad will flake off tiny white pieces into the air flow.  I have a ton of white flakes being caught in the filter and others that make it through are coming out of all of my central air/heat vents.  Most of the beds upstairs are covered in little white flakes from the filter.

Took me a little while to realize where the flakes were coming from, now too late to return the product.
