Air filter to use on a weber?

Howdy all
jus forked out for a weber for the darn 1300 (shit thing)
Any who, what airfilter cani use on it as i know you can use a k&n but cant justify ?30+ for one
Cheers all

Assuming you're running a standard airbox, if you cant afford a K&N or the like then the only option is stanrdard paper filter for ?3-4.

Cheers
