Which one? They vary ...although I'll say that in the filters that I've looked up, 19um appears to be the nominal value of high frequency.

Part Number: 51515
UPC Number: 765809515154
Principal Application: Chrysler Family of Cars/Trucks (57-70), Ford Family of Cars/Trucks (57-00), Mazda Trucks (94-00), Toyota Landcruiser (71-96) - (Two Quart version is 51773)

Height: 3.404
Outer Diameter Top: 2.921
Outer Diameter Bottom: Closed
Thread Size: 3/4-16

Anti-Drain Back Valve: Yes
Beta Ratio: 2/20=21/37
Burst Pressure-PSI: 275
Max Flow Rate: 7-9 GPM
Nominal Micro Rating: 19

Keep in mind that the listed nominal (in bold) at times disagrees with the statistical nominal (beta ratio) figure. In the above example ..the nominal (50%) is rated at 21um (Beta21=2 2=1/2=50% or 50% of the 21um particles are removed in their test and 19/20th = 95% of the 37um particles are removed.

So take this FWIW [I dont know]

You can find this data by entering the filter number of choice at Wix You can enter any filter number and it will puke out the above data if they make an equivalent.

Does that mean that the 51356 filter (http://www.wixfilters.com/filterlookup/PartDetail.asp?Part=51356) with it's beta ratio of 2/20=6/19 filters out 50% of the 6um particles and 95% of the 19um particles?

If that's the correct numbers, yes.

All Wix are rated 2/20 ..that's 50% (1/2) and 95% (19/20)..the other two numbers X/X+ are the particle sizes that are removed in those ratios.

I tend to think that this is a misprint (data entry?) since the nominal rating is 19um ..I think it was supposed to be 19/26 ..not 6/19. Some of the spec's are in error ..or conflict on the Wix site.

I thought that it sounded too good to be true, especially with the nominal rating of 19um. Too bad that's the only size filter that I use.
