Smoke Defender / smoke absorb bracelet

Smoke Defender
Smoke Defender

As we all know, secondhand smoke takes a toll on human health. “Smoke Defender” is a bracelet designed for smokers to reduce the harm of secondhand smoke. By using a small fan and activated carbon to absorb harmful gases inside the device, it can protect people from harmful secondhand smoke and keep the air around the smoker clean. At the same time, the screen on the bracelet can show the smoking quantity to remind people to smoke less.
