CFM NEEDED FOR HOT TUB ROOM?

Client wants to move Hot Tub indoors into it's own 9x9 room. Whole house HRV will be running continuously; I will add dedicated exhaust fan; considering Panasonic Whisper, but have no idea how much ventilation will be needed to exhaust moisture when tub cover is off. Suggestions?

I've had a hot tub for many years in an unheated room. I originally installed an exhaust fan, but have never needed it. Assuming cover is off only when in use, at most run a small (100 cfm or so) when in use. I'd seriously recommend not heating the room.
