Visually stunning but less effective than my other si carbon filter because the design prefers girth to height. The 14mm female opening is also a bit big and my bowls are a tad loose, which is advantageous in that I don't have to worry about the filtercomming up with the bowl when I go to clear the pipe.

Works well

Works well but needs too be refilled and with no direction where to get the refill jazz.


Hey Joe, Thanks for your honest feedback on the Grav Activated Charcoal Filter Attachment! You can actually find activated charcoal at your local pet store because it's used in fish tanks to keep the water clear. You could also easily order it online from Amazon or an online pet store. Here is an example of the same type of charcoal used in the Grav Activated Charcoal Filter Attachment: Hope this helps :)
