When you say AC blower, you mean Air Conditioner, and not Alternating Current, right? This confused me for way longer than it should have...

What do you mean that your car is not as inefficient as you had thought? Did you measure the resistors to see how much energy is wasted at each blower setting? Would be very interesting to know.

Your plan sounds good to me, although I've not looked into the specifics.

Paper filters are reusable, even more easily so than oil-based ones. Simply knock the dirt off by tapping it against a solid object like the pavement. If you really want to, use compressed air at a reasonable distance so as to not tear it and blow it out, or use a vacuum.

I never replace filters in any of my vehicles, including engine air filters, or HEPA filters in vacuum cleaners.
