MaxxAir makes a vent cover specifically for the Fantastic fan.
It's taller I believe.
I just used the standard vent cover over mine and it works fine.
Also unless you plan to run your vent on Hi speed a lot it won't
hurt to have the lower cover IMO.
We rarely run ours on hi because even a fantastic fan is noisy on
