Sometimes I notice black dust in the pitcher. What is that?Updated a year ago

It may look odd, but the black material in your reservoir is completely normal. As the water from the reservoir flows down through the filter, some of the filtration media (the black stuff) may float up through the filter and into your reservoir. This filtration media is what pulls contaminants out of your water using ionic absorption.

The filter is specifically designed to keep it contained so it won’t get into your drinking water. Feel free to rinse out your reservoir regularly (but never put hot water or soap through your filter).
