Good post. I have brought it up before that the race for more efficient filters is more for marketing to sell a higher margin oil filter than what is being required for the applications being applied to.Baldwin Filter's purpose in life is to match the efficiency of the OEM specs of the filter they are making. They don't try to filter out more, or less, they try to match the specs. They are well constructed and made in USA. So, if that particular OEM wants playground pebbles and bird nest to go through their filter, that is how Baldwin will build it, on purpose. They try to match the efficiency of the actual Motorcraft or Honda filter you would carry out of their dealership. You can buy filters from other filter makers that have 20 micron or smaller absolute ratings out there. Some of those don't match the OEM efficiency. In other words, the car makers own filters allow the bird nests to come through, that is what they want. Baldwin is not competing to make a filter that simply fits and takes out the tiniest micron of debris. Some industrial hydraulic filters OEM's require the 20 micron absolute or smaller ratings. Baldwin makes those filters to spec. for those companies also.
Sometimes "Good Enough" is just that, good enough and anything more has limited to no appreciable returns other than a decimal data point on a spreadsheet.
