K&N Oil Filter Betas?

[river_rat]

Has anyone else tried to contact K&N to get some idea of their oil filter efficiencies? I sent an email but never heard back.

I was just curious as to what they are and would like to hear something from the "horses mouth" or someone else that has rather than guessing.

Thanks in advance.

Have you tried contacting Champion Laboratories?

http://www.champlabs.com/

They make the K&N filters and they should be willing to give info on their filters.

I have not. Thank you!

Update: I got an email back from K&N yesterday asking what model filters I use, so hopefully they will send me some specific info on these.
Meanwhile, I don't know if it is a current efficiency rating or not, but I stumbled on this BITOG post from 2002: http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=309373&page=all
Stating 50% @ 16 microns and 98% @ 35 microns.

You missed my 2008 posting of specs for a K&N NP-6001 (Ford Powerstroke Filter):

10 um- 53.1 %
20 um- 95.4 %
30 um- 99.9 %
Capacity- 55.4 grams
Hydrostatic Burst- 558 psi
Element Collapse- 175 psid
Flow Rate- 20 GPM (J-806)
Betas- 10/20/30=2.1/21.7/1000

Thanks Jim! That's like I was looking for!
So it's comparable to the M-1. That's good to know.

The K&N HP-1004 I used, according to K&N via email on 9-30-09:
Filter media efficiency (per ISO 16889):



100% at 40 microns

100% at 35 microns

100% at 30 microns

99.4% at 25 microns

98.9% at 20 microns

97.1% at 15 microns

92.3% at 10 microns

82.5% at 5 microns

Wow ... that's quite a PSID before the element collapses. I would have expected it to be much less than that. It's too bad the manufacture's don't give data on PSID at some flow & viscosity point to give the customer an idea of flow resistance.

Fantastic! Twice better then Pure One (51% only at 5 microns)

p.s. But 82.5% is according to ISO16889. How much is it at common-used (Purolator, AMSOIL, CHAMP, FRAM, ...) ISO4548-12?

I don't understand why K&N have used ISO16889 (for hydraulic or fuel only) instead of ISO4548-12 (for lube oil).

Comparing two different ISO standards, so might not be a direct comparison there. The PureOne 51% @ 5 um is ISO 4548-12, where as the other is ISO 16889.

Probably to make it look better.
