a Beta ratio of less than ß2 on particles the size of talcum powder. Beta ratings can be used to explain the efficiency of filtration for all fluids, oil, diesel, petrol etc; it’s simply a measurement. It is important that both the micron sizing to determine the filter rating. Filter micron ratings are often based on one of these methods, but with many possible variations: A. Nominal Micron Rating (NMR) NMR usually means the filter can capture a given percentage of particles of the stated size. For example, a filter might be said to have a nominal rating of 90% at 10 micron. Your shirt sleeve may well have a Beta ratio higher than 2000 on particles the size of marbles. The same sleeve may have a Beta ratio of less than 2 on particles the size of talcum powder. Beta ratings can be used to explain the efficiency of filtration for all fluids, oil, diesel, petrol etc; it’s simply a measurement. For example, if 100,000 five micron particles were measured, on average, before the filter, and 100 five micron particles were measure after the filter, the beta ratio was 1,000. For a filter element particle rating to be valid, the manufacturer absolutely must advertise the beta ratio observed for that level of filtration. Beta rating is the most commonly used rating in industry for filters. Its comes from the multi-pass method for evaluating filtration performance (ISO 16889:1999). The Beta rating itself refers to filtration efficiency, however it should always be used in collaboration with the absolute rating to understand what contamination is likely to be seen in the …
A filter with an absolute rating takes out all particles the same size or larger than the rated micron size. A newer filter-rating system called the beta ratio is

For example, a filter might be said to have a nominal rating of 90% at 10 micron.
Beta stability is the measure of how well a filter element is able to maintain its measured Beta Ratio at pressure drops beyond the limits of the normal operating range. For example, beta 200 stability = 210 psid, means that the Beta Ratio for the rated micron size will not drop below beta 200 until it reaches 210 psid across the element. The nominal rating also represents an efficiency figure or degree of filtration. A nominal rating example is “95% of 10 micron” – where the filter prevents 95% of all 10 micron and larger particles from passing through. However, the nominal rating method is generally discouraged. Beta Ratio refers to the efficiency in which a given filter element removes particles of a given size. The Beta Ratio is calculated using the ISO multi-pass test standard 16889:1999. The test involves adding particles of a known size to the test fluid until the fluid reaches a saturation point, This efficiency, or beta ratio, signifies this is a pretty high quality filter media, meaning it would most likely be synthetic to achieve that result. When any filter can achieve a beta ratio of around 70 (just above 98% efficiency), we consider it to be an absolute rating. The Beta rating comes from the Multi-pass Method for evaluating performance of a fine filter element (ISO 16889:1999). Whether you do it yourself or send samples to a lab, fluid sampling should be performed upstream and downstream of the filter to get an accurate effectiveness of the filter. a Beta ratio of less than ß2 on particles the size of talcum powder.

The Beta Rating is the most commonly used efficiency rating in the hydraulics industry. This rating is based upon the Multipass Method for Evaluating Filtration Performance of a Fine Filter Element (ISO 16889:1999). Filter ratings are an often misunderstood area of contamination control. The most commonly used rating is the Beta Ratio, which is defined as the ratio of the number of particles upstream of the test filter versus the number downstream, greater than a given size. Using the Beta Ratio, a 5 micron filter with a Beta 1000 Rating, will have on
