Product review (1 stars): Filters same as original Honeywell product?  I say no.
I've owned my humidifier for years, and I could count on replacing filters 2, maybe 3 times per season.  These new filters seem to dry up and calcify (so they won't take up water) much more often.  I'm not even through the winter humidifier season and I've had to change them 5 times.

Bottom line, I think whoever is now manufacturing these filters is using some other material.  They don't work very well for me
