I poured a lotta mile thru 'em when I was an "apprentice" to be a dairyman.
Filters good fer gett'n foreign debris outta milk goi'N into cans. But, only garlic taste will pass thru GURNSEY milk while pouring mostly water thru.
However, I strain "spent" oil thru the filters, now. Good fer tractors, mowers, and service vans. Profitable when servicing car engines.
