Product review (5 stars): These are the ONLY filters you should buy for your Vornado Humidifier!
Believe me, I've tried so many of the less expensive off-brand imitators and none of them do as good a job or last nearly as long as these filters. You truly get what you pay for on this item. I've experienced no problems with them, and they are superior in wicking properly so that the fan actually puts out humidified air.
