Excellent Carbon Filter Adaptor

This carbon filter adaptor is far better quality than the Black Leaf adaptors I've been using. I recently dropped my Black Leaf carbon adaptor and of course it broke so went looking for a replacement and found this website and SI products. I am highly impressed with the quality and functionality of this unit. I also use Penn Plex Pro Carb Laboratory Quality Activated Carbon pellets. Chips tend to clog faster.

Honestly works way better than expected!

I got this for my double shower head bong that is about 16 inches tall. I have smoked a whole ounce out of it and it still looks brand new like i just bought it yesterday, and i haven't even had to change the carbon yet! Hands down best attachment you can get for your piece, works better than any ash catcher i have ever owned (trust me i have owned many) for much cleaner/ smoother hits and a much much cleaner bong.
