I use a water filter and I always see little black things that come out of the tap. What are those black specks? Sometimes they're so much and when they cluster together they look disgusting. Are they safe? I'm schooling in a different city, and the person that was leaving here left the water filter in the fridge, so I started using it. Other than that I probably wouldn't have and wouldn't have noticed those black things because I've never used a water filter before. We do not use a water filter at home, but I've never noticed them before back there. But I'm going to make sure I tell my parents to get one. Why am I seeing them here in the tap water in this city and are they safe?? These things are really disgusting. Are they supposed to be coming out of the tap? I'm even scared to cook with the water now. I always use the water from the filter to cook.
