On Royal Caribbean ships, 100% fresh ocean air is continuously supplied from outside. The air is drawn from one side of the ship for cooling and ventilation, then removed via exhaust on the opposite side of the ship. This continual intake of fresh air replaces the air in any space, with a total air change up to 12 times an hour in staterooms, and about 15 changes an hour in large public spaces. In local spaces, like smaller venues and your stateroom, fan coil units provide an extra layer of protection, continuously scrubbing the air of pathogens, using a high-grade MERV 13 filter that captures aerosols 1 to 3 micron in size with 90% efficacy— fine enough to filter colds, flu germs, and coronavirus. An independent study by the University of Nebraska Medical Center onboard Oasis of the Seas confirmed that cross-contamination of air between adjacent public spaces is extremely low, and undetectable in most test cases, thanks to this powerful system.
