Nozovent® Nasal Dilator

Do nasal dilators work and how do they help with snoring? 

Nasal dilators don’t cure snoring, but they can make a real difference if your snoring is caused by blocked or narrow nasal passages. Worn inside the nostrils, they gently widen the nasal valves, reducing resistance and improving airflow. This can ease nasal-based snoring, support clearer breathing through the nose, and reduce mouth breathing. 

They’re less effective if your snoring comes from the throat or tongue collapsing during sleep, in which case another type of solution may be more suitable. You can take our interactive snore quiz to help determine your snoring type. 

What’s the difference between nasal dilators and nasal strips? 

Nasal dilators and nasal strips are sometimes referred to as internal and external nasal dilators. Both aim to improve airflow, but they work in different ways: 

• Internal nasal dilators (or nasal valve dilators) are small inserts worn inside the nostrils. They gently hold the nasal passages open and are usually reusable, providing consistent support throughout the night. Some are designed to provide extra support for weak or collapsing nasal valves. 

• External nasal dilators (or nasal strips) are adhesive bands placed across the outside of the nose. They work by gently lifting the sides of the nose to open the airways. 

Many people prefer the comfort and reusability of internal dilators, while others like the convenience of disposable strips. 

Are there different types of nasal dilators? 

Yes. Internal nasal dilators (sometimes called nasal valve dilators) are small, reusable inserts worn inside the nostrils, while external dilators (nasal strips) are disposable adhesive bands placed across the outside of the nose. You may also come across magnetic nasal dilators, magnetic nose clips, or nose magnets, which are a more recent innovation. These devices include small magnets and are designed to hold the nostrils open in a similar way, helping to improve airflow and reduce nasal snoring. 

Are nasal dilators safe to use every night? 

Most nasal dilators are safe for regular nightly use. Internal dilators can be cleaned and reused but should be replaced after the period recommended by the manufacturer for hygiene. External dilators (nasal strips) are single-use and should be discarded after each night. Always read the instructions for use, as these include important details on cleaning, replacement, suitability, possible side effects, and any cautions. 

How do I clean a nasal dilator? 

Reusable nasal dilators should be cleaned regularly to keep them hygienic and in good condition. After each use, rinse the dilator under warm water and gently wash it with mild soap. Allow it to air-dry completely before storing it in a clean case. Always check the manufacturer’s instructions, as some types (including silicone nasal valve dilators) may have specific cleaning or replacement guidance.
