Frequently Asked Questions:

How does Theravent work?

Patented MicroValve Technology uses the power of your own breathing to create Expiratory Positive Airway Pressure (EPAP). This gentle pressure naturally opens your nasal airway to target and treat snoring. The valves are set in an adhesive that you place over your nostrils right before sleep. You will breathe in normally and then feel a gentle resistance as you breathe out. This is the MicroValves beginning to work.


Is Theravent effective for snoring associated with OSA?

Theravent is not intended to treat sleep apnea. Please see your doctor if you think you may have sleep apnea. Theravent, Inc., the maker of Theravent, also offers Provent® Sleep Apnea Therapy, which is indicated to treat obstructive sleep apnea.


How is Theravent different from nasal strips like Breathe Right?

Nasal strips are placed on top of your nose and help dilate your nostrils, reducing congestion. Theravent uses the power of your own breathing to create pressure that opens and supports your nasal airways.


How long does Theravent take to get used to?

Give yourself at least a week to get used to the feeling of Theravent. Some people may get used to the therapy in one night; for others it may take up to a week. But you will soon find that you get used to the new routine.


How do I apply Theravent?

  1. REMOVE: Peel paper backing to expose the adhesive.
  2. ALIGN: Using a mirror, center the device so that both nostrils are completely covered by the mesh area.
  3. APPLY: Place the device so that it completely covers both nostrils. Gently press the adhesive down against your nose to create a seal between the device and your nostrils.
  4. CHECK THE SEAL: Make sure the device is sealed around your nose with no wrinkles or gaps, since these can create air leaks. Air leaks reduce the effectiveness of the device.


  • If you are having trouble breathing in, remove the device and reapply.
  • You should feel resistance when you breathe out through your nose with your mouth closed. This means the device is applied properly. You can check the device by plugging the center hole in the device with your finger and gently breathing out. If the device is sealed, you should not feel air escaping around the adhesive. If you have an air leak around the adhesive, gently press down around the adhesive. . You should naturally switch to nasal breathing and your snoring should be treated. If a leak persists, remove device and reapply.Once you have a proper seal, breathe in and out through your mouth until you fall asleep
  • Make sure the area around your nostrils is clean, dry, and free of lotion.
  • Use a mirror to apply the device.
  • Users may require several nights to feel comfortable when wearing the device.
  • After use, remove the device by gently peeling the adhesive off each nostril. For sensitive skin, remove the device with warm water or while in the shower.
  • Apply the device just before you are ready to go to sleep.
