Filter quality!

The filters do a great job they just dont fit tightly in the return. Ever other brand I have used fit tightly in the return vent. These say 20x30x1. I get a musty smell when walking by the return I feel this is from the filter not being tight. There is a small gap at the top. Your filters are not true to size. The reason I say that is I have NEVER had a filter of any other brand fit like this. I bought enough for a half a year so I guess I will have to use them. Thank you Teresa Ensey
