The Theravent brand has the same technology used in sleep apnea treatments from another well-known device you might have heard of – Provent Therapy.

However, this product was only available via a prescription.  The EPAP technology used in the device helped many with OSA (Obstructive Sleep Apnea) to get a new lease on life.

Theravent made this technology accessible to others with sleep issues as well.

The brand incorporated the technology in a nose strip that changes airflow, affects the throat cavity and through this, has the potential to stop you from snoring.

A Closer Look

The Theravent strips are small, disposable adhesive pieces of fabric that stick to the front of your nose.

Each adhesive has small vents that regulate airflow to influence your snoring.

You can put it on before you go to sleep and peel them off again when you wake up.

Clinical Data and the Technology Behind Theravent

I’m going to start with the statistics that prompted me to give this a try. This was after trying just about everything and only finding negligible positive results.

It’s clinically proven that these strips can reduce snoring by up to 76%.

That’s a huge difference, and this is the technology that makes it happen.

What is Nasal EPAP?

How Theravent works EPAP is the acronym for Expiratory Positive Airway Pressure.  Basically, it helps regulate the pressure inside your mouth and the airflow, so you’ll inhale via your nose & exhale through your mouth.

You snore because your throat muscles relax, closing the airway to your mouth.  Then air must push through a very small hole (which makes a loud noise) or exit through your nose (which can also make a noise if your nasal passages collapse).

With these strips, when you inhale the MicroValves are open, but when you exhale they close partially. Now there’s positive pressure in your throat which forces the airway open through your throat and mouth, so there are fewer vibrations (less snoring).

Sounds easy, but it’s actually amazing technology.  And Theravent is the only brand that has FDA approval to use and sell this technology to the public in this form.

The best part of all is that I didn’t need a prescription to get this.

I was also impressed that Theravent uses hypoallergenic adhesive and Medical-grade fabric. Even people with sensitive skin and allergies can use this.

You probably see that these strips are activated by breathing through the nose. If you breathe in through your mouth while you sleep these strips will obviously not work.

The Range of Theravent Products

The Range of Theravent ProductsPersonally, covering my nose while I’m sleeping sounded a little uncomfortable.

It’s not natural, but this is exactly why the brand created its range of products:

  • Theravent Lite: This is for light snorers but is also ideal to get you used to sleep with this new device.
  • Theravent Regular: It provides moderate resistance, so it’s effective for general snorers. If you’re working up to the next level of strips, these will make for easier crossover.
  • Theravent Max: If you snore loud and heavy these will give enough resistance to create the right pressure inside your mouth.

I love that unlike many other manufacturers, Theravent didn’t expect me to make a huge capital investment while I figured out which ones worked the best.

The trial pack contains two of each of these. I could test them out and then buy the most appropriate ones in bulk.

How to Apply a Theravent Adhesive

It’s pretty simple, but I had an occasion where the strip was misaligned. This made me restless because I couldn’t breathe comfortably, so positioning is very important. These points should help get the fitting correct:

  • Ensure the skin around your nose is clean and dry (no lotion)
  • You first peel a paper film off the back of the adhesive
  • Hold the adhesive on both ends with your thumbs and forefingers
  • Position it, so your nostrils are covered
  • Now press it upwards firmly so it can seal against your skin
  • Check that there are no wrinkles as this will break the seal and alter air flow
  • Close the small vent in the middle with your finger while you exhale; if it stays in place your seal is tight enough

At first, do this in front of the mirror; it’s much easier. Eventually, this process becomes second nature, and you can quickly do it in bed before you switch off the light.

You will know the fitting is correct when you are able to breathe easily, but with you feeling resistance when you breathe out.

There shouldn’t be any air escaping out around the edges either.

Then, you can get into bed and concentrate on breathing in through your nose and out via your mouth.

The pressure inside your mouth and throat cavity should prompt this to happen even when you fall asleep.

Pros & Cons


  • It’s a no-medication way to stop snoring
  • The brand offers a 30-day money back guarantee
  • Easy to come by
  • You don’t need a prescription
  • Trial pack available


  • Takes up to a week to get used to and many people give up due to the initial discomfort
  • It only works for certain types of snoring (nasal snoring)
  • Continuous expense of around $1/day instead of a once-off investment
  • Taking off the strip can be painful
  • Tends to leave an odd taste in your mouth

My Experience

I’ll be honest about the first few times I tried it, it does take quite a few nights to get used to.

While the brand mentions three to five nights, it took me a full week:

  • It felt weird to have something sticking to my skin
  • My breathing was different, so I didn’t relax at first
  • I was concerned it would fall off during the night, so I didn’t want to try sleeping in my normal side sleeping position

I would advise you to push through and not give up on day two or four.  I have tried many anti-snoring devices and have learned to give each product a proper chance and thorough testing before coming to a final conclusion.

Thanks to the desperation I tried the entire trial pack, and on night number six, at last, my sleeping app was showing considerable improvement in the amount of snoring that was reduced and the improvement in the quality of sleep I was getting.

One thing that motivated me was my partner who could report an improvement in sleep since day three. I must have started snoring less by then, which is good news for whoever shares your bed.

Important Notes

One downside to these strips is that I can’t wear them every night.  I suffer from allergies and when I have a really stuffy nose—or when I have flu—they don’t work. It feels too uncomfortable, and they don’t counter the snoring at all.

Who are Theravent Anti-Snore Strips Recommended For?

Basically, anyone asking the question – do snoring strips really work.

Looking at Theravent Snore Therapy reviews, I do find one thing that stands out.

There’s no question that the technology works, but it only applies to a certain set of circumstances.

You must be a light snorer, and you must be a nose breather.

Obviously, these will not work if you are breathing through your mouth the entire night.  Hence, when I have allergies, or my nose is clogged, using these will be impossible.

Is It The Same As Regular Nose Strips?

So why try Theravent anti snore strips if regular nose strips don’t work for you?

Because it’s completely different technology.

Nose strips work from outside the nose by physically adjusting the nasal passages. With Theravent the pressure works inside the nose and throat cavity.

It’s less invasive and a more natural process, so it should feel more comfortable to you.

The one benefit of nasal strips is that they can still work when you’re battling with a cold or allergies.

Pricing and Warranty 

Unlike some anti-snoring products that are only available online at Amazon, you may find this at your local store.

The brand even helps you find an outlet with its website’s store locator.

Bulk packs are also available making it slightly cheaper per unit.

The pack of 20 strips is available for $17.99. That’s a minimal expense, and it gives you a good chance to see if it works for you.

What should give you peace of mind is the 30-day money back guarantee, so you’ll never waste your money trying this.


The short answer is that yes, the Theravent’s EPAP device works. It did for me. But there are limits to its functionality.

It doesn’t combat sleep apnea at all, and since it doesn’t work the moment I have a stuffy nose, I know it won’t work as well for heavy snorers.

For them, a MAD or TSD device is still the best option.

Light snorers…I really think you now have a new option.

My Rating: 3.7

Which Product Should I Buy?

questionEvery person has a unique mouth and different needs for their particular snoring, so one that is perfect for one person, may not be the best option for another.

With well over 100 products on the market it can obviously be quite daunting to decide, “Which one?”

To help ease the decision process I have created a comparison chart where you can effortlessly assess each product and its features, price, pros and cons. I have also written several detailed reviews for those devices that I believe to be leading products.

If you would rather not spend a lot of time reading reviews, please take a look at the article linked here: My Mouthpiece Recommendation. It’s a list of three products which I believe, based on my extensive experience, are the best options available to people who suffer from snoring.
