Finding the right size - here's how


The right size is particularly important for the Nasivent tube to work optimally. Only if the nasal dilator fits well can it gently widen the nostrils without pinching or slipping. As the anatomy of the nasal passages varies from person to person, the Nasivent Tube is available in five sizes (XS to XL).

There are two simple ways to find the right size:
The most straightforward method is the Nasivent Starter Set, which contains all five sizes. You can try out each variant at your leisure and find out which is most comfortable to wear. The tube should be tight enough not to slip, but at the same time not cause any uncomfortable pressure.

Alternatively, you can also measure your nostrils from the outside with a ruler to get an initial indication of the right size. You can find measuring instructions and a size chart directly on our homepage - there you can quickly and easily estimate which size is likely to fit best. This method is particularly suitable if you want to order your individual size straight away.

Regardless of whether you test or measure: as soon as you have found your ideal size, you can reorder it individually at any time.

Difference between Tube Plus and Sport model

The Differences Between Nasivent Tube Plus and Nasivent Sport

The Nasivent product family offers two high-quality nasal dilators that enable free nasal breathing – whether in everyday life, during sleep, or while playing sports: Nasivent Tube Plus and Nasivent Sport.

Both versions have been proven to improve nasal breathing, enhance oxygen intake, and can be used in a variety of ways – for example, to reduce snoring, relieve nasal congestion, help with allergies, support deviated septum issues, or aid CPAP therapy. Athletes in particular benefit from improved breathing, especially in endurance sports.

Nasivent Tube Plus was specifically developed for daily and nighttime use. It is made from especially soft, flexible medical-grade silicone, ensuring maximum wearing comfort – even during extended use. It is ideal for use while sleeping, for snoring problems, or as a gentle alternative to nasal sprays.

Nasivent Sport, on the other hand, is primarily designed for active individuals and sports enthusiasts. The slightly firmer material ensures a secure fit, even during intense movement. By specifically widening the nasal wings, more air can be taken in during training – which significantly supports performance and endurance.

Good to know: Both products can generally be used for all the mentioned purposes. The main difference lies in the material and the resulting individual preference – softer and more comfortable with the Tube Plus, firmer and sportier with the Sport model.

Both versions are available in five sizes – for an optimal fit – and also come in a starter set. While the Tube Plus features a discreet transparent look, the Sport model makes a bold statement in blue or white.

Conclusion:

Whether at night, during the day, or while training – with Nasivent Tube Plus and Nasivent Sport, you get two flexible solutions that specifically support your nasal breathing – depending on your lifestyle and personal needs.

How long can you use the tube

The Nasivent Tube – whether in the Plus or Sport version – is designed for regular and long-term use. When used and maintained properly, a nasal dilator can be used for several months or even several years. The exact lifespan depends on individual usage frequency, care, and personal preference. Many users replace their Nasivent Tube approximately every 6 to 12 months.

To extend the lifespan and ensure hygienic use, the Nasivent Tube should be thoroughly cleaned with warm water and mild soap after each use. Occasional disinfection, for example by briefly boiling it in hot water, is recommended. After cleaning, the product should be stored dry and protected – ideally in the storage box provided.

Thanks to its durable medical-grade silicone, the Nasivent Tube is not only comfortable to wear but also especially easy to maintain – making it ideal for daily use, whether at night while sleeping or actively during sports.

When and for how long can the Tube be worn?

The Nasivent Tube can be worn for several hours at a time, depending on individual needs – whether during the night, while exercising, or in everyday situations. Many users wear it continuously throughout the entire duration of sleep, typically between six and eight hours, to consistently improve nasal breathing and effectively reduce snoring. It can also be worn for extended periods during physical activity or in cases of acute nasal congestion.

Thanks to its high-quality, medical-grade silicone, the Nasivent Tube is particularly skin-friendly, flexible, and comfortable to wear – even over longer periods. It is important, however, to pay attention to personal comfort: if any pressure, irritation, or discomfort occurs, the Tube should be removed and, if necessary, a different size should be tried.

A proper fit is key to a comfortable wearing experience – especially during prolonged use. That’s why both Nasivent Tube Plus and Nasivent Sport are available as starter sets with five different sizes, allowing users to determine their optimal size individually.
