Guard (XG4967).
The published efficiency of the XG is 97% at 20 microns. Does is say that right on the box of the XG4967, or something different? How do you know the smaller XGs don't suffer from a worse efficiency rating like the smaller PureOnes? See below.

Note what footnote 2 says:
"FRAM Group testing of filter efficiency and capacity of models equivalent to PH8A, 3387A and 6607 under ISO 4548-12 for particles > 20 microns."
I was thinking of trying an XG7317 instead of a PureOne PL14610 on the Altima someday, but only if the XG really does filter better.
Zee0Six, That's exactly my problem. All filters in my size filter worse than the larger sizes of the same brand. The XG4967 is rated at >20u size, no different than anybody else's.
I realize the Fram does this @ 97% and a pure one @ 99.9%, but I was just looking to try something new and wanted to know what the group thought about the XGs. There's so much negativity toward Fram's Extra Guard,(and I understand why because of the cheap construction),that I wanted to be sure the XG was a more trusted filter. I've cut open my used Pure one filters and they look really nice. maybe I post some pics. I don't like the relief valve on the pure one. I think the coil spring in the XG is much better. I noticed a post recently of the relief valve on a Bosch that was stuck open.
Thanks!
