Some of the more important parts of sleep apnea machines are not typically noticed during their use.
The filters (there are two) ensure that the air used in continuous positive airway pressure (CPAP) therapy is safe and healthy to breathe.
If you've ever changed a filter anywhere else—from an air conditioning unit, a whole room air filter, or a smokeless ashtray, as examples—you'll know that these hidden gems are hygienic workhorses, capturing billions of particles of dust, pathogens, and other undesirable matter floating, otherwise invisible, in the air around us.
CPAP filters work just as hard and need attention in order to ensure your CPAP machine remains in solid working order for years to come. They are also your first line of defense for good respiratory health.
