16 Pack Bamboo Charcoal Air Purifying Bag, Activated Charcoal Bags Odor Absorber, Moisture Absorber, Natural Car Air Freshener, Shoe Deodorizer, Odor Eliminators For Home, Pet, Closet (16x50g)

I like the different sizes of the bags, and the fact that it deodorizes, etc. However, not sure how to reactivate, or activate it, does it need to be in direct sunlight or can i leave it in the car,, does it reactivate thru the glass?? Confused as i do not have direct sunlight.

Ok. So, I built an office cubicle and I originally stained my desk outside. Then when I brought it inside and installed it, I realized it wasn't as glossy as I wanted, but I was not about to take it back outside. So I glossed it in that tiny office. The smell was insane. I aired it out as much as I could. Then I bought these charcoal things and put 4 large ones in the room. In 2 days, it smelled like nothing! No chemical smell anymore. I keep one in my car as well. I will buy again. Remember to bring it outside once a month to let the sun recharge it.
