Fit-out dust is plaster, gypsum and paint. It bonds to wet coils and fills ducts. A filter swap is not enough if the unit ran during sanding. We deep-clean indoors and, on ducted apartments, we treat the ducts as contaminated until proven otherwise — camera first if the landlord wants proof.
Tell the contractor to cap returns during sanding next time. You are paying for their dust now.
