thats pretty crazy. Do you stick ur fingers in there? i have a 18.8 little sista still waiting on the roor diffuser it was on back order . I have a friend that has a carbon filter and ive smoked countless bowls, after a while resin does build up and the smoke turns yellow equaling to harsher hits and barely taste of nugs. im kinda iffy on the CF adpator theres some pros can cons like most products. just me .2 cents

nice bong though
legalherb Reviewed by legalherb on . Local 18.8 Shop Bong with RooR CF/Bowl Here's my 18.8 bong that I've been using for a while. The downstem has 6 diffuser slits and an open bottom. Just got the RooR carbon filter and bowl today. (RooR glass screen too, fits nicely!) The bowl's quite the monster, it didn't look so big in the picture. Oh well :stoned. But the carbon filter is amazing. Keeps everything below the carbon filter clean as a whistle so you can same lots of time cleaning. Not to mention gives a great hit for a long time and when it gets kinda nasty you Rating: 5
