A recent FDA safety communication has warned patients and health professionals that the agency has not cleared any devices that use ozone gas or UV light to clean, sanitize, or disinfect continuous positive airway pressure (CPAP) devices.
From 2017 to 2019, FDA officials said they received 11 reports from patients who developed a cough, difficulty breathing, nasal irritation, headache, or asthma attacks when they used ozone gas-based products to clean, sanitize, or disinfect their CPAP devices and accessories such as masks, tubing, or headgear. No adverse events have been linked with products that use UV light.
