There certainly is. Electronic stores..(the BIG ones) often carry a

I see no reason to eliminate static charge build-up on the inside only.
I have a plastic ShopVac that builds up enough static to suck the hair
off my head on a dry day like today....I mean, the frickin' thing
levitates and sticks to the wall like balloon!!! The air flow on the
inside, builds up the static on the outside of the container.
