Refiling scubbers is no longer cost effective. You can buy a new scrubber for less then it will cost you to buy enough Carbon to fill the old one...
Umm.. I don't know where you live but I can get 50lbs of activated carbon for ~100$
The 2nd MOST expensive filter they sell is $99 so yes for the same you could buy a new filter. You're welcome!
