Don't worry, I am not selling charcoal product. But there are some of these products in the market lately. Actually, I wanna sole agent some of these products, but didnt take off. Em... lets see, I assume you wanna get rid of any pungent smell that may arise. Try not to use air freshener, some ppl are allergic to it. For any job, always think of maintenence free and try to keep things simple. Simple to beautify. Have you thought of cleaning the ventilator ? What if it break down and you could not get the right size again ? Too much electicity stuff is bad for our health. Anyway, charcoal are " CARBON " products, they have a tendency to absorb all bad smell near them. u could also put a small piece in you fridge if it gets too fishy. Maybe also your shoerack
