Warning! The filters I received were just over 1/2 inch smaller than the label said they should be. north clean. 18x24x1 (inches) means exactly that. I read a lame apology for replying to another bad review - some bullshit about the lack of industry standards and differences. There's no excuse for your product labeled 18 x 24 x 1 to actually measure 17.45 x 23.5 x 3/4 inches. I've used all sorts of filters and so far I've never had this problem - ie. They were the same size as advertised (18 x 24 x 1). I'm so stunned by this nonsense I don't even know where to start. It's not even close. All other filters tend to be intentionally slightly oversized (by a hair or two) for a snug fit. I can't even get the damn things in because they're practically smaller than the inner lip of the intake, causing them to partially go into the intake. Now I've settled it with Revain.
