Mobil1 filters are supposed to be the best. I've never noticed a difference between any filters thought. I change my oil pretty often though so it never gets a chance to get really dirty. I just use OEM filters. I got a case of them on sale from
http://www.autopartsonlinecanada.com/ ...package that with a couple fuel filters, pcv, in-cabin filters, bearing seals and other consumables and you'll easily be over the $75 required for free shipping. It's quick to your door too cuz the warehouse is somewhere near Burnaby.
