I dont keep my bike in a woodshop. Probably not the best place to keep it.For the avg cost of around $60-$100 for a single BMC filter ( yes i know it is reusable ) and since the BMW filters are replaced once every 12000 miles I would have to put more than 50k miles on the little G310GS for it to be worth the investment. I can live with a little less performance ( less than 1% ) and a lot better air quality getting into the engine. With BMC filters only stopping particles larger than 7 micron my bike would be breathing like a 50 years old cigarette smoker in only a few days. My bike sits in my garage that is both a metal and woodworking shop. Dust and particulates in the air all the time, and in some cases down to 3 micron and highly abrasive. No thanks I will stick with paper filters. I use personal breathing filters down to 1 micron everyday, don't know why I would want my bike to have anything less.
