The BLITZ® SUS Power air cleaners are made from top quality T-304 stainless steel. Totally unique, the entire filtration element is made from a fine stainless steel T-304 mesh (200 micron mesh and 150 micron crown).
This mesh means the filter will never wear out, and have substantially less restriction than any other filter. Another feature is the super fine pattern of the mesh. This straightens the airflow and dramatically reduces (restrictive turbulence). The BLITZ air cleaners also have fine mesh at the top of the filter, further improving the airflow capabilities..

I couldn't find what the micron rating of other airfilters is to compare, anyone know?

Dust retention wise, a paper filter is, in fact, a sieve which must have holes large enough to allow air to pass through. That hole size will allow dust particles of 35 to 40 micron to pass - UniFilter's sticky oil catches everything above 4 to 5 micron. Given that engine wear is caused by dust particles larger than 15 micron - UniFilter air filters are way out in front when it comes to dust retention

The ability of an air filter to protect your engine is generally measured using a testing procedure developed by the Society of Automotive Engineers identified as the SAE J726 procedure. We subject a sample of our filter designs to this test procedure using Coarse Test Dust, which includes particles ranging in size from less than 5.5 microns to 176 microns. As a point of reference, a human hair is approximately 50 microns in diameter. The result of the above test procedure is a specific air filtration efficiency number. This efficiency number represents the percentage of test dust retained by the filter and thereby kept out of an engine. Our goal is to design our air filters to achieve maximum airflow while targeting overall filtration efficiency at 98%.
