We introduced Dent breath pastilles through a viral campaign. At www.lungtester.com we created an online lung test where people can measure their lung capacity. To perform the test you use either a microphone or your headphones as a microphone. A woman's voice carefully guides you through the test and its simple instructions. When your equipment is activated it's time for the test, to blow as hard as you can into your microphone. The test will be interrupted by Dent because it has detected bad breath.
