Forget nuking your Smoke Buddy in the microwave. Place 2 to 3 silica gel packets (which can be found in every new pair of shoes, or inside of your old perscription medication bottles) inside of your Smoke Buddy. The silica dessicant will absorb/eliminate even more moisture and carbon before it even gets through the internal filter, and it won't add any exhalation resistance either. Just my 2 cents
