Provent Anti-Snoring Nose Vents

There are actually two different types of stop-snoring products that people refer to as ‘anti-snoring nose vents.’

The first is a product that is also known as a ‘nasal dilator.’ This type of product is essentially a small tube or device that you insert into the nasal passages to ‘widen’ them out, thereby making breathing easier.

The second one (which is the type that we refer to as an anti-snoring vent) is a type of EPAP (expiratory positive airway pressure) device that contains small ‘vents’ that allow air to be inhaled freely, but that make it more difficult to air to be exhaled. These are usually stuck onto the nose with adhesive, to create an air-tight seal over the nasal passages.

Anti-Snoring nose vents

While both of these types of stop snoring products could, in theory, be classified as ‘anti-snoring nose vents,’ the two could not be more different.

To put the difference into the most basic perspective, one would have to say that both of these products treat completely different types of snoring.

But in this post, we are (for the most part) going to be discussing the second type. Here is what you need to know.

How Are Anti-snoring Nose Vents Meant To Work?

Anti-Snoring nose vents are actually pretty simple to use. Most of the time, they come with little adhesive strips so that you can attach them to the opening of your nostrils. Once you do, they allow you to breathe unhindered when you inhale – but they create resistance when you exhale, which helps to build up expiratory air pressure inside of your airway.

How ProVent Works

This creates pressure that, in theory, helps to treat the root cause of soft palate vibration – which is the most common type of snoring. Soft palate vibration occurs when the soft muscle and tissue of the airway relaxes and closes on itself – thereby creating restriction. When you breathe, the air rushes through this newly restricted space, and the soft tissues of the soft palate vibrate.

This creates the sounds that we have come to associate with snoring.

So these devices help by increasing the air pressure in the airway, which helps to keep the soft tissue from collapsing inward.

Granted, this is mostly in-theory. These types of devices do not always work as perfectly as planned… but, they do in some cases.

Do We Believe That Anti-snoring Nose Vent Method Works?

This type of product certainly has its merits. It also has its downsides though. We are not as pleased with how these products tend to perform as we are with some… but on the same token, we also feel like they tend to work better than some as well.

If soft palate vibration is causing your snoring problem, then we would probably recommend a product like an MAD or a tongue retention device first, as these are a bit more technical and help to treat the root cause of the problem more directly. We would also recommend healthy lifestyle changes to help you work toward a state of better overall health.

But – with that being said, we also really like the idea of these products. In a way, they help to provide CPAP-like technology for a fraction of the cost. And while they are not as efficient, they can work, and are worth a try if you don’t want to use something quite as invasive as an MAD.

The Positives

Here are some of the upsides to Anti Snoring Nose Vents…

  • They are pretty inexpensive
  • They tend to work well in some cases
  • They aren’t very invasive
  • They help to treat the root cause of soft palate vibration

The Negatives

Here are some of the downsides…

  • Some people don’t like how they look and feel
  • They do not work for everyone
  • They aren’t as efficient as some other methods
  • You have to keep buying them (they are usually disposable) to keep using them

Who Should Use This Product, And When?

Any adults, age 18 and over, should be able to use this product. If they are having trouble breathing through their nose, then this might not be the right type of product for them. This also may not be the right type of product for someone who gets really bad allergies or nasal congestion.

Who Needs Anti-Snoring Nose Vents

As for when you should use it, you would need to use this product every night during sleep to see the benefits.

This is one of those products that you would have to use continuously in order for it to work.

Who Should Avoid This Type Of Product?

This type of product (EPAP nasal vents) likely isn’t suitable for kids. It would also not be for you if you tend to suffer from allergies or a lot of nasal congestion, as it could make things a lot more uncomfortable. Also, if the root cause of your snoring is in the nasal passages, this product will likely not help.

Scientific Studies

There have been quite a few scientific studies conducted on nose vents (both the EPAP type and the nasal dilator type) since they first came out. One of the most well-known studies to be conducted on this type of device was published in the Journal of Clinical Sleep Medicine.

It was called Long-term use of a nasal expiratory positive Airway pressure (epAp) device as a treatment for obstructive sleep Apnea (osA). In this study, Obstructive Sleep Apnea was treated with a device called Provent, which is basically an EPAP nasal vent that fits right into this product category.

Provent is an interesting product because it uses EPAP therapy to build up positive airway pressure in the subject. This is accomplished because the vents require more pressure for exhalation than for inhalation.

According to the study, patients who used Provent actually had reduced AHI numbers and were significantly less sleepy during the day than they were when they didn’t use the device.

Scientific studies actually show that products like this are quite useful for helping with not only snoring, but also OSA.

Another very interesting study (this one a review), called Nasal Expiratory Positive Airway Pressure Devices (Provent) for OSA: A Systematic Review and Meta-Analysis, was a review and meta-analysis. Therefore, it was exempt from IRB protocol.

But… it was designed to review current studies about Provent and EPAP, and give a comprehensive answer to the question does it actually work, according to all of the studies that have been conducted on it?

56 different articles were look at first, but later on, authors agreed that a total of 18 original studies and 10 conference papers met the inclusion and exclusion criteria. The combined studies followed 920 different patients, from a range of different ages and backgrounds.

You can view the review information here.

Here is a statement from the review document Conclusion, which does a good job of citing the findings of the review.

“Although nasal EPAP does not completely eliminate OSA, there is an improvement in OSA outcomes based on polysomnography and questionnaires (quality of life and sleepiness).”

The document also goes on to say that there are a number of benefits that make the device more effective. These include the fact that it is portable, that there are really no reported side effects from their use, that they do not require electricity, and that they are more tolerable than PAP treatment.

The review also goes on to say that “further studies are needed to evaluate long-term efficacy and delineate clinical and polysomnographic profiles of patients who would be best suited to this therapy.”

As you can see, this is an anti-snoring remedy that has actually been pretty thoroughly researched. It has also shown effectiveness in the treatment of obstructive sleep apnea, which is pretty impressive.

Nasal Vents That Are Not EPAP Devices

There are some nasal vents on the market that are not actually EPAP devices, though a lot of people think that they are. This is especially true with a lot of generic-brand nasal vents being marketed right now.

Many such vents also work as nasal dilators and air cleaners… but this is certainly different from them utilizing EPAP technology.

For best results, always make sure to read thoroughly about any device that you plan to purchase. Nasal dilators can still work, but they are traditionally less effective than EPAP nose vents.

Before buying a nasal vent, make sure that you…

  • Are aware of what type of product it is
  • Find out for sure if it uses EPAP technology
  • Know exactly what company produces it
  • Research the device to see if there are any clinical trials that vouch for its effectiveness
  • Look into customer reviews to find out if it actually works for the people who buy it

We actually really like YouTube reviews, as opposed to regular written reviews… because it seems that YouTube videos are usually more legitimate. They are harder to fake, and take a lot more effort to produce.

Plus, most YouTube reviewers don’t necessarily want to be known for lying or misleading their followers about products!

At any rate, make sure that you know what you’re getting before you spend your money on a product… especially if the company seems vague or unclear about what the nasal vent actually does.

The Nasal Cycle

When it comes to nasal dilators, it is believed that they may contribute to helping with a phenomenon known as ‘the nasal cycle.’ Very few people are aware of this, so we will discuss it here. We will also discuss what nasal dilators have to do with it.

When we breathe, we actually breathe with a physiologic phenomenon where alternating congestion and decongestion of the nasal passages produces a change in resistance from one nostril to the other.

In one study, roughly 72% of human subjects demonstrated a clearly defined nasal cycle.

This also helps to explain why, when humans end up feeling congested in their nasal cavities, they usually feel it more on one side than the other.

The difference in resistance is usually pretty slight, which is why most of the time we do not notice it. But it may help to explain why nasal dilators can help to prevent snoring and mouth-breathing during sleep.

Nasal dilators (not the EPAP vents) help to keep both nostrils open during sleep. It is also reasonable to assume that they actually may work better than nasal strips, as nasal strips work less directly by pulling the nostrils outward, instead of pushing them out from the inside.

So in this sense, there is certainly something to be said for nasal dilators, and the fact that they may be able to help offset the negative effects of the nasal cycle.

If you experience a clogged single-nostril on a regular basis, this may actually be a remedy that could help you.

Keep in mind, however, that EPAP nasal vents do not work for this purpose. As we discussed earlier, nasal vents will probably not be very comfortable for people who are already suffering from a nasal congestion problem.

It can sometimes be confusing to talk about nasal dilators and nasal vents in the same context… but it is important that you know how each type is different from the other.

Remember… EPAP nasal vents are more regularly used to treat obstructive sleep apnea, while nasal dilators are used to open up the nasal passages and treat nasal snoring.

What Is The Difference Between EPAP and CPAP

CPAP stands for ‘continuous positive airway pressure.’ EPAP stands for ‘expiratory positive airway pressure.’ 

These are two very different things. But when it comes to sleep apnea, they both basically seek to accomplish a similar goal.

CPAP utilizes continuous air pressure to help keep the airway open during sleep. This is accomplished through the use of a CPAP machine, which is the ‘gold standard’ for obstructive sleep apnea treatment. It uses technology to produce the pressure. EPAP, on the other hand, relies upon the patient alone to supply any positive air pressure. In the case with nasal vents, this is accomplished by putting vents over the nostrils that make it harder to breathe out than to breathe in. By supplying this air resistance, they are trapping air in the airway and raising the pressure… which also creates more room and helps to alleviate sleep apnea.

CPAP has been very successfully used to treat sleep apnea, but it also has a low compliance rate in comparison to other devices. CPAP is bulky, cumbersome, and can be quite uncomfortable if it is not fitted right. It is also difficult to take on trips, as it is not necessarily ‘mobile.’

EPAP therapies (Like Provent and Theravent) have actually gained a lot of traction as potential alternatives to CPAP, at least in some certain cases. In one study, titled A review of EPAP nasal device therapy for obstructive sleep apnea syndrome, it was actually shown that “Patients generally prefer EPAP to continuous positive airway pressure (CPAP), and there are no serious adverse effects from its use.” 

The study also went on to say that CPAP was more effective, but that the two different therapies got similar enough results that EPAP could potentially serve as a legitimate alternative.

The study sounds positive, though it concludes that more research is needed to gauge the effectiveness of EPAP when compared with CPAP and other sleep apnea treatment options.

Mandibular advancement devices can also be used for the treatment of obstructive sleep apnea. Not all of them are cleared for it, but there are some that have received FDA clearance for the treatment of OSA. These are marketed as alternatives to CPAP as well.

Final Thoughts

Anti-Snoring Vents can do a lot of good for some people – but they are not quite as effective as some other treatment options out there. If you are suffering from snoring that is caused by soft palate vibration, then we would actually recommend a mandibular advancement device or a tongue retention device first.

Of course, if you don’t want something quite that invasive to start out with, then a product like this can actually be awesome to try. It can be especially helpful to find a brand that offers a money back guarantee, in case you don’t end up being too crazy about it.

And there is also CPAP to consider. CPAP is definitely the number-one recommended treatment for obstructive sleep apnea… though EPAP has gotten very good results alongside it in clinical tests. It really may all come down to your personal situation.
