Any car peeps here

I have a roto fab, I bought it off someone else so I didn't receive any paperwork.

It's been on my car for a couple of months, on his for a couple. I'm just wondering about the frequency of recharging the filters. K&N is every 50k, but I am not sure on this one. I've seen info on every 10k miles, if so, it's a bit of a pita as I have to basically take it apart just to get the filter out.
