My filters came nicely boxed

My filters came nicely boxed and they were in perfect condition. I replaced the same size that was in my air-conditioning vent area and I had a gentleman out to clean my vents and he told me my size is actually probably a 16. 5 so it would be a 16. 5 x 25 by one. Kind of crazy, but the product was perfect.
