A volcano ash/air filter question. He lives right next to a volcano, which is expected to erupt soon. Was told to duct tape panty hose over the air intake to keep ash from clogging the filters? Will this work, and what color should he get? Guys say it should work, and suggest taupe. Clean or replace when it gets clogged.
