I took my carbon filter out of the tent today because I have to turn it around for my new setup. When I took it down I noticed how dirty the pre-filter was, so I started to take it off and soon realized I had opened a bucket of worms. It was very difficult to remove, so I just took out my little shop vacuum and gave it a once over with that. It looks a lot cleaner now. Do you think its cool now for another session, or should I bite the bullet and take it off entirely and clean it with water? I saw a thread in here where someone reminded someone else not to forget to clean their pre-filter. Any opinion?
Peace
