Many years ago, when NAPA changed over to thier own brand of filters (WIX)they had a study that showed paper filters usually have an efficiency of about 98%, while oil bath runs between 20 and 35%. Oil "bath" is a misnomer. The air is not bathed. The incoming air changes direction and centrifugal force flings the dirt particles into the oil. At idle the oil bath filter is next to useless. It is most efficient at high air flow. Paper filters the same at any air flow. Use NON-detergent oil in an oil bath as that oil allows the dirt to settle. Detergent keeps it in suspension. In the dryland farming country they used to put an oil bath on top of a stack that fed the semi-cleaned oil to a paper filter - sort of a pre-cleaner.
