Ok ok.. first let me tell why I refer to myself as a carbon expert. I am familiar with not just carbon in general but also the various different kinds of carbon and it's use for filtration in air as well as water. I was born and raised in the aquarium industry and my main filter product for aquariums consist mostly of carbon(something my father invented years ago). From my experience growing up I learned what carbon can do, can't do and what kinds of carbon to use for various applications.
I have also been an avid smoker since an early teenager and being 33 now I've used and experienced most kinds of filtration possible for smoking and even trying some of my own ideas.
I will say at first when I saw i could get a carbon attachment for my Roor that I was skeptical of how efficiently it would work at removing toxins, tar etc from my smoke. After obtaining a carbon filter an attaching it to my roor i couldn't of been more pleased. If you think the diffuser you have in your roor filters your smoke cleaner, having the carbon filter gives you a whole new level of filtration. It produces a much smoother smoke with far less tar. You will even notice that past the carbon filter your bong/roor will barely get dirty or have any tar build up. Once I noticed this I realized that the same tar build up is happening inside my body and removing it from the smoke gives a better smoking experience and is better for my overall health.
Using carbon to filter your smoke does nothing at all to make your smoke taste bad. it does not remove the taste. Those individuals who have used carbon and mention it has had an adverse affect on their smoking experience were most likely utilizing a carbon filter where water filtration was not utilized afterwards and may of inhaled minor bits of carbon dust. The carbon dust itself does not taste great and could be a reason why some say it adversely affects your smokes taste. ii would always suggest using a bond like a Roor which would use water to remove any dust, which should only occur if you use a low quality dusty carbon. A dusty carbon can be risnsed ahead of time to remove any dust and will still filter your smoke with no problem.
When choosing a particular carbon go to any large aquarium store and choose a coconut shell based carbon. Coconut shell based carbons are much better at filtering air. Also avoid purchasing any carbon that come sin pellet forms. Pelletized carbon is basically compressed carbon dust and does not allow for good air or water filtering as air/water will go with the path of least resistance and go around any pellets. Always choose Coconut shell based carbon that is in granule form.
Now that we are pas that, for those of you who would like the ultimate form of filtration here is my suggestion. Although it does cost some money to purchase.. It combines Vaporization, Carbon, a diffuser in water, and ice.
This can easisly be achieved with a Roor bong which has the carbon filter, diffuser and ice notiches to hold your ice in the middle of your tube where the smoke sits the lognest. That will cover ur carbon, diffuser and ice(IMO if you got this you're doing perfect already)
Now you ad the vaporizer, but how do you get a vaporizer to attach to the roor?? Problem solved with a french company who produces a vaporizer called the Herborizer.

If you take a look a the link you will notice their 'heat chamber' attaches to a glass to glass fitting and can replace the 'bowl' on your roor.
There you go, I know it's an expensive proposition to do. If you can't afford the vaporizer as well I would high suggest getting the Carbon filter for your roor or if you can make shift one for your own device.
