Arrived not working condition
I'm not sure how this came packaged, but all scratched up. It also had debris inside the mouth peiece when removing the cap?! Looked like hay.. You can also hear the charcoal moving around. I don't know if the manufacturer is having issues with this product, but the purpose is to filter air which can't be done when arriving dirty (not putting my mouth on) and charcoal is moving around freely.
