Inspect your's annually. If you can still see the metal screen all around, then it's not dirty enough yet for a recharge, even if the cotton pleating is dirty
If you ever find any part of the screen is covered in dirt, then it's time
If you put on a lot of miles, it won't hurt to recharge it before it's due, but overdoing it is a waste as they need some dirt buildup to work more efficiently ??? That's their claim. So don't over clean it

I put very little miles on my daily driver (>5K/yr), but I re-oil my filter every 20K or so because 'it wasn't red anymore' 
My mileage may jump to 10K with the new job, but look how many years I could go between re-charges |
I've got a roto fab intake I picked up from someone else who was trading their car in. He had it on his car for a few months only (bought new) then on mine for a few months. It was full of bugs, but still red. I did the recharge so at least I know where it started from. Almost at 40,000 kms on my car already....
