Step 1: The charcoal will be dusty at first. Give it a light rinse and brush off any excess ash.
Step 2: Transfer the charcoal to a pot of water and boil for 10 minutes. Drain the water and allow the charcoal to cool completely.
Step 3: Once the charcoal is completely dry, fill your favorite container or bottle with water and place the charcoal inside. During this time the charcoal will adsorb the impurities in the water. For best results, let charcoal work its magic for at least 2-3 hours before drinking. The longer the better!
Step 4: Feel free to leave the charcoal in the container and refill as necessary. The charcoal will continue to work for 2 to 3 weeks until it needs to be re-activated.
Step 5: Re-activating the charcoal is simple. Boil it for 10 minutes, let it cool, and it's ready to go.
Notes
Filtering time depends on the quality of your tap water. The suggested filtering time for a personal water bottle is 2+ hours. For carafe/pitchers, the suggested filtering time is 3+ hours.
