Backflow vs Normal Incense Cone Burn Speed Comparison

Check out https://www.artbykazami.com/faq for answers to common questions about backflow incense.
For this particular brand of incense, the backflow cone lasted around 19 min, and the normal cone lasted around 25 min. Backflow will always burn faster just because of the improved airflow that the drilled hole provides, but the speed difference is not so dramatic as I've seen suggested elsewhere-at least, not for this particular brand of incense.
