Product review (2 stars): thinner, lower moisture output
thin and smell like wet cardboard.  the original that came with the filter was about twice as thick as this one and lasted about 2 months.  first set of replacements I bought of another brand were about as the original and lasted about a month.  this set of replacements are thin and lasted only about 2 weeks, and required the fan be set higher to get the same moisture output as compared to using the thicker filters.  wish I could find the original, but will settle on the first replacement I tried (the one through subscribe and save).
