Ecogard XA5592 Efficiency

[badtlc]

For anyone interested Ecogard sent me filter efficiency data for this common Subaru air filter. They claim it is 100% efficient down to 10um.

Anyone know how that compares to the industry?

100% efficiency down to 10 microns seems a bit hard to believe.

What needs to be asked is what is the efficiency using the ISO 5011 test standard with the "fine dust" not the "course dust" in the ISO test procedure.

Also, good info when looking at air filters is what's the new/initial pressure drop in inches of H2O at some specific CMF.
