They may well be a waste too.

I got 3 fans designated for that use. All three wound up with sagging
blades. Fiberboard. Two were so bad they looked like open umbrellas. I
made new blades from 1/4 ply, no sagging.

I've got one in a lanai that was installed in 1998 that is still going just
fine.
The room is essentialy open to the outdors in humid Florida.
Blades are plastic. You have to pay attention to what you are buying.
