Well, I've never tried to make my own. However after using my store bought scrubber for two years, I decided to take it apart and just replace the carbon.
From my experience, it was quite expensive and VERY DIRTY and have never done it again. I just replace it and try to dispose of the old one without taking it apart.

That's my 2 cents worth
keylime Reviewed by keylime on . Carbon Filter Review I saw on some other boards, that some people made their own Carbon Filter to hide the smell, especially for the stinky strains. I know that I can make one quite cheap and easy, I was just wondering if any of you picked up a store bought carbon air cleaner. If so, post up the type/model and what you think of it! Rating: 5
