Optipillows EPAP Mask Optipillows alleviates snoring by preventing upper airway obstruction by using Expiratory Positive Airway Pressure for treatment of snoring. Optipillows EPAP Mask is FDA cleared and is used like a CPAP nasal pillow mask, but without the tubing or machine. Optipillows EPAP Mask comes as a kit which includes headgear, the proprietary EPAP valve, and 3 sizes of nasal pillows. It's lightweight and comfortable, and does not require a prescription. Optipillows is reusable, lasting up to one year. Optipillows EPAP Mask is the only EPAP device on the market that offers adjustable pressure. During inhalation, the membrane opens allowing users to breathe in easily. During exhalation, the membrane closes and redirects the expired air through a narrow opening on the side of the valve. This creates Expiratory Positive Airway Pressure (EPAP) in the mouth and back of the throat, which helps keep the upper airways open and prevents snoring. Based on the needs of the user, the pressure can be adjusted by rotating the patented valve sleeve to make the opening larger or smaller. Tired of waking up throughout the night due to snoring? Need a comfortable solution that you can live (sleep) with? That's why we created Optipillows EPAP Mask. It works like a CPAP mask, but without the tubing and machine. Optipillows also requires no power source. What Causes Snoring? During sleep muscles and tissues around the throat relax and settle toward the back of the mouth. This causes obstruction of the upper airway which leads to snoring.
