 This was found on the bed next to where the homeowner's head lied. My biggest concern with stuff like this is I want you to also know the homeowner's on a CPAP machine. This is next to their head while they're using a CPAP machine. People that use this typically stop breathing in the middle of the night. So what this does is ensures that you consistently have airflow throughout the night. But if you're having trouble breathing, you also want to make sure that the air that you are breathing is clear of all contaminants. So having rotten food, roaches, stuff like that. Something that you want to make sure you're not contributing to the factors that would make it harder for you to breathe.
