RE: Gritty residue in reservoir and other ResMed 11 problems
Do you live close to a freeway? I lived next to a freeway in southern Ca. and every morning my vehicle would have this coat of dirt, or so I thought. I was informed by A long term resident it was brake pad dust from stop and go traffic on the freeway and people just accept it. LOL.
