The silicone tubes were my prior favorite. The tubes, on the other hand, take up some space in the nose, restricting airflow slightly. These stretch the nostrils outward without putting pressure on the sensitive septum or restricting airflow. They come in a two-pack; I used the first one nightly for almost 6 months until it started to clog up my nose. We'll see if the second one lasts as long as the first. It's a fantastic offer. Great quality and the size really suits me.

Absolutely the best nasal dilator on the market! It is superior in both airflow improvement and daily usage impact. I've used Nozovent for every sleep for 4 years and dont feel rested without it. I have never experience discomfort or sores on inside of nose - unlike some other nasal dilators. Also easy to clean and iHerb has the best price in market as well.

These simple devices are really magic for improving your nasal airway, if you have difficulty breathing through your nose in bed at night. They’re easy to use, have no side effects, and each one lasts for many weeks. They’re also good value, at least if bought through iHerb.

I bought this for me and my boyfriend. He has nasal valve collapse and this helps him sleep at night and to breathe better during his workouts. The material (ingredient) is a nice sturdy silicone and it springs the nostrils out for better breathing. The quality is nice but the size is to big for me. Would recommend for people with larger noses.

I just ordered for first time, and for the beginning it feels uncomfortable until you get used to it. I believe it is different experience for everyone in particular, for the people who like to sleep in different positions, sometimes in the morning when you will wake up you will have to look for the device in your bed sheets ( at list this what I am doing sometimes).

The best for my sleep. Can't sleep without it. Have tried other brands but this one is the best as others were too uncomfortable and some were painful.

This has been really helpful They’re easy to use, have no side effects, and each one lasts for many week I have been using Nozovent for years It guarantees a snore free sleep experience

These things are massive and were quite hard to place accurately in my nose! Maybe its just me :) Once placed they do work....just not for people that sleep on their front :)

I got these for my husband and they worked pretty well and he said they were comfortable. After a few weeks they seem to kind of lost their effectiveness.

It doesn't work for us 100%, but there's an improvement in the loudness of snoring. but very uncomfortable to wear, the parts you insert inside nostrils are large. It tends to slip out during night.
