I just recently installed a new canister and Chris is correct, the bottom is sealed.

Yup, that is why there is a filter. GM part 7026014.
It's simple to change. The filter is a flat disc about 4 inches in diameter and 3/8" thick. It sits in a recess in the bottom of the canister that
is probably only 3 1/2" in diameter. The smaller diameter holds the filter in place. The whole bottom is open on the original style canister. You
have to unfasten the canister from its mounting and access the bottom surface. Just use caution around the vac tube fittings as they are fragile.
You have to kinda scrunch up the old filter to get it out. And you have to distort the new filter a little to force it in to place.
In the late 80s they changed the design, sealed the bottom and added a fresh air vent to the top. Service parts would be like this, so some may no
longer have a serviceable filter on the bottom.
