It's amazing how many sized filters for AC units there are, and they are down to the 1/2", 1/4" sometimes even 1/8" or 1/16" size differences. You want to be sure that you get the right size as that fraction helps secure a snug fit for maximum filtration. Not only that, but being off by a fraction too big can make the difference in a tight fit or no fit at all. This model and size fits exactly. Just what was needed.
