As far as l can tell this is a pure option for my cpap. But it is gettable with proper planning, etc. Works great for decanting acrylic paints.

Activated charcoal is great for whitening teeth. Can also be used as an ingredient in toothpaste. Can be added to homeopathic recipes for added benefits.

Besides that it is a decent sized bag that comes vacuum tight. A little goes a long way.
