Boy, it was not that easy pulling and cutting the filter element from the cardboard frame without ripping off some of the filter media. Cutting it wasn't that easy too Looks like it will work OK, I installed the filter with the wires facing upward. I figure there is a plastic grid already molded into the filter holder's bottom. It cost me about 10 bucks for the filter, with up to eight more pieces I can get from what's left over,
I think I will just buy the Toyota filters next time. It was just too much work and a hassle to cut away the 3M filter material from it's cardboard frame, and I think that some unfiltered air can escape through the sides because there's no way to get the edges perfectly straight.
P.S., just curious, which way does the air flow through the filter? From top to bottom, or from bottom up??

look on the side of the 3m filter, it should tell you which direction of airflow

the air flows from above the filter housing to below. set the filter accordingly. if using "web absorber" or another filter with a separate activated charcoal layer, put the charcoal layer on the bottom of the filter tray and the green filter material above that. cut the black plastic to fit and lock it on top. mine took all of 10 minutes to make and install and "web absorber" brand is also cheaper than standard filters. it was $10.00 at home depot.
