Same in desert shield desert storm ...... sent back home for cases of panty hose to make pre-filters over the stock air filters on our vehicles..... Wheeling these days I carry multiple AFE filters for just dust . Ever see the K&P lifetime oil filters ??

Also bypass filters for oil, coolant and transmission fluid by amsoil work well.
I had an air hose and an air tank on a m978 hemmtt fuel truck. Was a daily routine to pull the air filter and blow out the fine dust that accumlated in the filter. That pressurized air helped me keep my rifle clean too.
Im still trying to figure out how We took the 2015 Cruze in for an Oil Service and a few other things and left with this Truck that only had 32 miles on it when We left...
The only answer I can come up with is: If Mama aint happy, then NOBODY is gonna be happy thing.
Im not up on those but will check them out. Damned good idea on the Pantyhose, quite the different use of them from back in the WWII Days;)
