A lot of users wonder what the difference is between bubblers and bongs. And quite honestly there isn’t a lot of difference between the two. In fact a bubbler is essentially a portable bong that has a built in filter. Bubblers are a great combination of pipes and bongs because they are small enough to carry around but also has the feature of water filtration. A traditional pipe does not have the filtration feature like a bong, but also does not require additional attachments a bong would required. Thus, I thing a bubbler is the best of both worlds for smokers who are looking for a small piece but doesn’t want to spend the money to invest in a bong.
