Photo misleading
AS others said the photo of the filter is misleading. It shows the filter inside the shell, this is not the case. The shipping was fast and I received two filters (I have a split AC system so I needed two) nicely packaged. However it is not "just slide in" you need to place the filter in the shell of your previous filter. For me this is much better than dealing with an accordion style filter where you have to use four combs and have enough dexterity to figure it all out in the dark tight space of the attic. I was surprised to learn about this style of filters as I am a new home owner who is used to 3M filters from your local Target store.<br />This does the trick and it is rated for a year so I'll deal with it again next year. So far so good.
