Buying Our Filters
Online vs In-store pickup
All Filters sold online for shipment will be sold in cases of 12 filters per case. If you'd like to order online and pick up in-store, at our Stuart location, please see our "store pickup" page or call us to order as few as 1 air filter in our 1" and 2" standard sizing.
