CY: Yow, that's cruddy. And it looks like the air flow is blocked.
Should be open. Is it possible some one walled off the air vent?

I stuck my hands in there, and the opening is above.
Plus, it used to work, and nobody has touched it since.

It *was* embarrassing when I saw that cruddy filter.

I almost didn't want to post a picture before I cleaned it.

According to the manual, there is supposedly a "v-shaped" set
of filters at the blower itself, but I haven't been able to
find them yet.
