A while back, I interviewed some industry experts on the shelf life of oil filters. I was advised that 3-5 years is a safe average and that cellulose media based filters are more at risk to high humidity. A rusty tapping plate is a sure sign of poor storage and a filter so tainted isn't a safe bet. Dry, temperature stable conditions are obviously best and could extend the shelf life of any filter but I got to wondering...
Here's how I now store filters. We have a Food Saver vacuum pack do-dah and I have been putting all of my filters into these, along with a package of desiccant and the end off the box for ID. Unlimited storage life as I see it. Buy when it's cheap. Store until you need it with no worries. This is the latest batch I've put into "suspended animation."
