Baldwin Filters new Micron Ratings
Baldwin Filters MICRON RATINGS NOW AVAILABLE ON BALDWINFILTERS.COM
WHAT IS A MICRON
Contaminants are measured in microns (μm). A micron is a unit of measure equal to one millionth of a meter. The average cross-section of a human hair is 50 microns. The human eye cannot see anything smaller than 40 microns in size.
WHAT IS A MICRON RATING
A micron rating is used to indicate the ability of a liquid filter’s media to remove contaminants of a particular size. A filter that is efficient in catching large 50 micron particles may allow virtually all smaller particles to pass through. Therefore, in order to make sense, efficiency ratings must include both the amount (%) and size (micron) of contaminant removed.
NOMINAL MICRON RATING
Indicates the filter is capable of capturing at least 50% of a specific size particle.
ABSOLUTE MICRON RATING
Indicates the filter is capable of capturing at least 98.7% of a specific size particle.
COMPARING FILTER PERFORMANCE
When comparing against other branded filters, it is important that testing is done under identical circumstances. Knowing not only the micron size, but also the efficiency is crucial when determining the filters’ performance capabilities.
