Cabin filters and mice

[Bobiam]

My past 2 cabin filters have been home to mice and they have chewed minor amts of the filter material, but do not appear to have gotten into the heat/AC system. I'm doing all I can to kill mice and last year killed 26 between my 2 garages.

I need a metal screen reinforcement or guard on my cabin filter to prevent serious damage. Some intake air filters have them, but I can't find a brand of cabin filter with wireprotection. Ideas???

Also, a screen above or below the filter would do well if I mad or purchased one. Any knowlege of such a product?

Thanks......... Bob
