Review on MOSO NATURAL: 200g Original Air Purifying Bag (4 Pack) for Cars, Closets, Bathrooms, Pet Areas - Unscented, Chemical-Free Charcoal Odor Eliminator by Stan Myers

I bought this to combat the smell of cigarette smoke in my Buick Enclave (to give you an idea of the cabin size) because me, my partner and some of our friends smoke. If you're like us you smoke with the windows down and still try to blow it out the window but it still gets in. I put all four bags in the car: one on the passenger side, one on the second row on the driver's side. , two in the third row. And they seem to really limit the cigarette smell so far. When I get in the car after a few hours of waiting, I notice that the smell has greatly reduced, but not completely gone. I believe. I took off a star because while they do seem to help, all four are needed when each is designed for odor control in a space much larger than the internal cubic space in the enclave.
