Taking proper care of an ASV machine can keep it working properly over time. The most important steps that you can take to keep your ASV machine in good shape are asking your doctor about maintenance and consulting the device's user's manual. These steps can help you make sure you follow the proper cleaning and upkeep procedures for your specific machine. Keeping the device and accessories clean reduces your risk of inhaling dirty air. You may want to lightly clean the mask every day, while cleaning, disinfecting, or replacing other components on different schedules.
