Hello and good evening! Something in my house makes me sick and i don't know for sure what it is. So i want to exclude every possibility. Is it possible that an activated carbon filter emits dust particles that pollute the air and if so,do they have to be recognized as black dust at all? And could such kind of dust be unhealthy to produce allergies and dizziness and tiredness? I do more believe it could be the vinyl floor covering emitting plasticizer gas or something but i want to make sure the next flat is clean of everything harmful.
