Air Purifying Bag All-Natural Bamboo

This deodorizer bag is made of 100% bamboo charcol that is supposed to last 2 years. It is supposed to help prevent excess moisture, mold, humidity and musty smells. Helps against allergens and bacteria and help odors. The bag is made from a burlap type material. To refresh the bag you just place outside for an hour.
I am currently trying this bag out in my my kids bathroom. For some reason it smells like metal or sulfur. I placed this bag on their bathroom counter. So far I have noticed a decrease in the smell. I love the design of this bag. It has a rustic look to it that works with the decor. I also love that it does not give off a scent to mask the odor you are trying to get rid of. I also do not have to worry about it getting moldy or stinking because of the moisture in the bathroom.
I am really surprised at how this bag has been working. I would recommend it to anyone looking to elimated odor with a natural product.
I received this item free or at a discounted price in exchange for my honest opinion.
