Home Water Filter – What are the little black things that come out of the filter?

by admin

I forget the type of filter, but on the top part (before the filter) tons of little black things keep coming out of it. This happens for all the filters even brand new. I noticed sometimes very small ones can get into my filtered water. What is this substance and is it safe?

It’s just charcoal that is used for the initial filtering process. It is harmless.
