I think you can probably get the filter aftermarket for cheaper too. It's not a hard thing to replace if you have the tools handy.
I always had odor issues if I didn't turn on the HVAC. Even with just outside air or recirc on and HVAC off for defogging the windows, there was always a slight odor. I usually turned on the HVAC and then set the desired temperature to as close to the outside temperature to avoid HVAC actually trying to heat or cool the cabin air. This way, I still got defogging but without a major hit to EV range.
