What are the black particles in my pitcher and how do I get rid of them?
Edited
The particles in your pitcher are excess Granulated Activated Carbon (GAC) pieces that have escaped the filter. These are not harmful to consume and do not reduce the functionality of your filter.
These particles are typically flushed out in the preparation stage, but it's possible for them to appear in your pitcher during use. To reduce them, please remove your filter from the pitcher and re-rinse the filter under running water. Be sure to shake actively and thoroughly until the water from your filter runs clear.
Please note that GAC particles are not harmful if ingested.
