Passengers in XX1 and XY2 boarded the aircraft in ZZZ wearing neck/face masks. They removed those during flight and put on white mask with a filter valve that had hose connected to it and the other end connected a powered air filter that hung around their necks. When I talked with both of them I advised them they could not use the air filter or a mask with a valve. He began to argue that he called reservations and was told it was fine. He then demanded for me to show him where it said that. I pulled up the face mask information with no valves he took picture of page. At that point passenger took her mask off and replaced it with the neck/face mask she wore on boarding but he did not. When he was ready to deplane he changed mask he was wearing back to the neck/face mask he had originally worn as he boarded.
Flight Attendant reported passengers wearing non-approved face masks.
