This is the latest information I got from Subaru Japan/Japan Direct Import Service:
" Cabin Air Cleaner: Catalogue says that this cleaner works by the electrical power of car battery.
......P/N G3015PA000 ...It is 43,900JPY or $481.77 US
Cabin Air Cleaner circulates air in the cabin by electrical power of car battery, and cleans dust and the stench through a filter in it. This cleaner is controlled by a switch that is installed around driver's seat. it starts working for 5 minutes with Hi-mode linking with the air conditioner; then it is changed to Low-mode automatically. Manual for the installation is also attached in the box, and we heard from Subaru that you can install it easily. (I will translate the manual if you purchase.)
Solar Cleaner: Catalogue says that a fan of this cleaner works by "solar electrical power", and removes stinks of the cabin. After that, good and light smell of jasmine remains. You should think this equipment as an aromatic. Actually, this equipment has a solar battery in it, and a fan works without any sources of power. But it works only for an aromatic, and doesn't work for the cleaning of air in the cabin. Also, liquid in it has to be purchase once it runs short. You can install this anywhere you prefer because this equipment is fixed by a double-side tape."
