The Mute nasal dilator uses a discreet, dual-loop design that fits inside the nostrils to enhance airflow by up to 38%, as clinically tested. Its adjustable left and right stents allow for minor fitting customizations, accommodating asymmetrical nasal shapes. The soft, pliable polymer construction is FDA-registered and biocompatible, offering a balance between flexibility and structure.

Each pack includes three sizes to help users identify their optimal fit. Once properly adjusted, the dilator sits low inside the nose with only a minimal visible bridge. While not invisible, it's less conspicuous than adhesive nasal strips. Most users report immediate breathing improvement, with some noting enhanced sleep quality and reduced snoring frequency. 

However, comfort is inconsistent - some experience irritation, pressure, or even internal sores with extended use. Fit also varies; certain nasal anatomies may find the device too short or too wide.

The product is reusable up to 10 times per unit, which can offset its price compared to disposable alternatives. That said, the cost may still feel steep for what is essentially a molded plastic clip, especially if a preferred size needs to be purchased separately later.
