Y. M. Sin:
I emailed you a description of the air cleaner system I am looking at adapting. If it doesn't get through (Electrical shortages in California have been playing havoc with our ISP/internet service) I have provided a link to the company below.
The device I am thinking about using for traffic situations is an Austin Air Jr. Air cleaner - http://www.austinair.com
. I checked with the factory, and they said it should run fine off a power inverter, and those are only $30-40 for a 150 watt 12V to 120V model.
The whole system would be rather like installing a stereo amp and subwoofer.
I have used these in my home for several years, and they are extremely good at removing dust, odors, and vapors.
