It doesnt fit like I thought it would. 16 is smaller than the normal 16 I receive when buying from the store. . . Trying to make it work but may need a different size

Great Filter at a Great Price!

Filters of this quality are usually 2x the cost at major retailers. We have several dogs constantly shedding and these filters keep my allergies at bay. Not to mention my last shipment was received the very next day after I ordered it. My A/C maintenance guy let me know about FilterBuy and I'll never buy any others.
