Product review (1 stars): Did Not Work Well
I got the humidifier used last year in time to use for winter.  I bought a filter from eBay for last winter and it worked fine for the whole four-plus months.  This winter I tried to reuse the filter, but it stopped wicking after a few weeks.  I bought the two new ones assuming each would last a winter.  The first only lasted about three weeks.  I tried turning it over and got another week-plus then it stopped wicking again.  Now Im using the second one.  I don't see any difference between what I got last year and this year, but they certainly perform differently.
