5 pack of 100 gram activated charcoal sachets; 500 grams in total per package. Each sachet measures 3 x 5 inches.
Are these toxic to humans, particularly babies, or pets?
Activated charcoals are 100% safe, non-toxic, and recognized as "GRAS" (Generally Regarded As Safe) by the FDA.
How long do they last?
Rather than expire, they become saturated at which point they can be reactivated by drying in the sun for 4-6 hours.
How often should they be changed?
We recommend changing them with reactivated charcoal sachets every 2-3 weeks or less in high humidity areas.
