Research shows that external nasal dilators (strips) can reduce nasal airflow resistance during inhalation and exhalation. In a study of 47 subjects, nasal strips reduced nasal airflow resistance by an average of 0.5 cm H₂O/Lps.

Another study showed that a nose strip reduced nasal resistance by about 39% compared to no strip.

When the mouth is kept softly closed, nasal breathing can become the primary airway , which research shows is associated with lower resistance and more stable airflow dynamics. One study found that mouth breathing is linked to increased airway resistance and more problems with upper airway collapse.

According to a systematic review, research on mouth taping is still limited and for some with nasal blockage, there may be risks. Consult a healthcare professional before use if you have any breathing difficulties, nasal congestion, or underlying health conditions.

You get two well-shaped components – a nose strip and a mouth tape – Designed to be used together or on their own. Instead of searching for two different packages, you get a ready-made evening kit in one solution. The material and fit are selected to be skin-friendly and comfortable during the night, making it easy to integrate into your evening routine.
