Ozone is a toxic gas that can kill bacteria and viruses, but there is a cost. If the concentration of the ozone is strong enough to kill bacteria and viruses, it is also unsafe for people and animals. Companies that manufacture devices that emit ozone are required to disclose that information. The SoClean CPAP sanitizer machines work in sterilizing machines, but the manufacturer has failed to disclose that its products emit ozone, according to a SoClean lawsuit. In fact, SoClean has claimed the devices are “safe” and “healthy”, the lawsuit claims. SoClean CPAP sanitizer owners may be able to join a class action lawsuit against the company for falsely advertising the safety of their products.
