Does anyone know why a brand new water filter that's still in its packaging would have dirty spots on the filter?
It has plastic on it, but there's dirt underneath it.
Is this normal?

@perceptivei that's carbon dust from manufacturing. that's why you have to rinse and put water through the filter before use. it won't hurt you
