We could all use a change of scenery and a breath of fresh air— daydreaming of your next vacation is great for now but few things come close to the real thing. When you’re ready to get back out there, rest assured, you have a comfortable home away from home waiting for you on board. Part of any memorable cruise with Royal Caribbean is the lengths we go for your safety and well-being. We even have an app that makes planning your day-to-day seamless, maximizes the hands-free parts of your vacation and gives you more time to just enjoy your getaway.

Every detail is important to us, including the quality of the air you breathe on our ships. Each ship in our fleet is filled with 100% fresh, filtered air. At the center of how that’s made possible is our robust HVAC system—heating, ventilation and air conditioning—that continuously supplies clean air indoors by taking in and filtering the ocean air.

Watch and learn from experts and scientists who break down how the effective HVAC systems work on board.


Whether taking in a show at Two70, enjoying a tasty dish at Chops Grille or Izumi, or relaxing in your stateroom, you can breathe easy. This HVAC system and its multiple layers of filters and other features make it virtually impossible for aerosol particles (like those from a cough) to pass between spaces. And that’s certified by an independent assessment conducted on a Royal Caribbean ship, thanks to a team of scientists from the University of Nebraska Medical Center—a leader in coronavirus research and clinical trials—and the National Strategic Research Institute.
