Product review (5 stars): Best price for OEM filters
I have a Honeywell 360A humidifier. These are OEM filters and this 3 pack is the best deal.  If you live in the mid-Atlantic region, you'll need 2 filters for a fall/winter season.  It's getting pretty cold this week and the system kicked on today.  Depot sells them for $12 a piece.  If you have Prime, get these now!
