Review on Bamboo Charcoal Air Purifying Bags 4-Pack: Natural Odor & Moisture Absorber, Car Smell Air Freshener | 2x200g, 2x150g by Phanikumar Larsen

Sometimes I think I smell mold in my room. I bought these as an exception and maybe just being in my head will help. The directions were kind of clear, just put it in the sun to "freshen it up". Before my shift I took a bag and placed it in front of the dash and when I got back to the car I couldn't tell the difference. And to keep the bedroom smelling nice, I keep the rest of the bags in my room and they don't need to be exposed to sunlight until they need to be "freshened up". I don't feel much difference in my not so big bedroom.
