       FDA Cleared 
The proprietary valve allows you to breathe in with minimal resistance, but during exhalation, the air flow is redirected through a narrow side hole with more
resistance to air flow.  This resistance generates positive pressure in the back of the mouth during expiration alleviating upper airway obstruction. The pressure during expiration can be adjusted to your comfort level simply by rotating the sleeve to close or open the side hole.
Safe, Effective , and Convenient
Ideal for use during travel, flight or camping
 
 
Snoring
Snoring and airway obstruction are due to events occurring in the upper airway.  At end expiration, the upper airway is most susceptible to collapse, because the pressure is low, upper airway is narrowest, lung volume is smallest, and muscles are most relaxed. Consequently, when inhalation begins, and a small negative is created, it causes potential upper airway collapse. With the EPAP mask, collapse of the upper airways is prevented by maintaining a positive expiratory pressure during expiration. The EPAP mask works using expiratory resistance technology that have been shown in clinical trials to be effective in preventing upper airway obstruction. The EPAP mask is easy to use. If you tried other expiratory resistance devices previously, you will like OptiPillows EPAP Mask. The EPAP mask is reusable, and can be used perhaps up to 1 year.
 
How much pressure is generated?
 
The pressure during expiration can be adjusted by rotating the sleeve to close or open the side resistance.
​
With side resistance fully open, it generates 1 to 3 cmH2O of pressure.
 
With side resistance 50% closed, it generates 3 to 7 cmH2O of pressure.​

With side resistance 75% closed, it generates 8 to 14 cmH2O of pressure.
