After how many miles do you need to change the cabin air filter in a Toyota?

It all depends on where you live. I usually get between 50 and 60,000 miles between chances but after the fires that we had here in California all the smoke and ash got trapped in my filter and every time I turned on the fan it smelled, so I change it. Mine is located behind the glove box in both my 2003 4runner and my 2008 Tundra and only takes about 10 minuets to change it. Instructions came with the new filter when I bought it from an auto store.
