I have read and heard of people using pre-filters on their air cleaners. But have yet to fine anything in forums. I travel cross country each year and have been in very dirty environments. Like my trip last year. I drove through Texas, New Mexico and a part of Arizona ... when somewhere in Texas was on fire and the farmers were plowing for their planting. The debris in my air cleaner was black and mostly blocked it. I have a reusable filter and all I did was take the time to clean it and on the road again. If it was paper, I would be changing it out each time it was plugged, until I was out of the area. It was bad on I40 then.Has anyone used a pre-filter before ?If so, what was your conclusion of it's effectiveness ?
