If you noticed in my picture the 1 x 3 board that the filter bracket is attached to has (2) steel "T" supports braces. The first time I went to remove my filter to winterize the 1 x 3 board came completely off. The way the factory stapled this board in to attach the filter house to wasn't structural sound enough to hold anything. I got another 1 x 3 board (a inch or so long to overlap another stud) glued and screwed it to the back of the existing board and put (2) steel "T" support braces on it, Solid as a rock now.
Might also mention, the factory guy on the filters said I didn't have to replace the filter every year if it looked good and wasn't used a whole bunch that season. Just remove it when winterizing, let it air dry and re-use next season.
