Asonor Anti-Snoring Spray Review: Does This Nasal Spray Stop Snoring?
Verdict at a glance
Asonor is a Danish nasal spray (30ml, ~£15) that targets throat tissue via nasal application. Manufacturer trial: 3 of 4 users saw reduced snoring. Best for mild to moderate palatal snoring; not for sleep apnoea or nasal-origin snoring.
2026 testing notes: easy nightly use, no taste, bottle lasts ~30 nights. Mixed Amazon reviews (3.4/5) reflect variable results. For more reliable snoring reduction, a mandibular advancement mouthpiece remains the proven choice.
What Is Asonor?
Asonor is a nasal spray designed to reduce snoring by coating and tightening the soft tissue at the back of the throat. Unlike decongestant sprays that target nasal blockage, Asonor's solution travels from your nostrils to the throat, where it firms up the tissue that vibrates during sleep.
It's manufactured by TannerMedico, a Danish company, and has been on the market for over 15 years. The product claims that 3 out of 4 users experience reduced snoring.
Key Specifications
- Type: Nasal spray (throat-targeting)
- Bottle size: 30ml
- Application: 4–5 pumps per nostril before bed
- Rating: 3.4/5 on Amazon (7,600+ reviews)
- Lasts: Approximately 25–30 nights

How Does It Work?
Snoring occurs when the soft tissues in the throat relax during sleep and vibrate as air passes through. Asonor addresses this by:
- Lubricating the throat tissue to reduce friction
- Tightening the soft palate and uvula so they vibrate less
- Opening the airway slightly by reducing tissue laxity
This mechanism targets palatal and throat-based snoring — the most common type. It's different from nasal strips or nasal dilators, which only address nasal airflow restriction.
Who Is It Best For?
- Mild to moderate throat snorers — soft palate vibration
- People who dislike wearing devices — no mouthpiece or strip needed
- Travellers — compact 30ml bottle fits in any bag
- Those wanting a non-invasive first step before trying mouthpieces
Not ideal for: Severe snoring, obstructive sleep apnoea, or nasal-origin snoring. For nasal congestion, a nasal strip or humidifier would be more appropriate.

Our Verdict
Asonor is a convenient, non-invasive option for people who want to try something before committing to a physical device. The fact that it targets throat tissue (rather than just nasal passages) is a genuine differentiator.
However, the mixed Amazon reviews and reliance on manufacturer-funded studies mean expectations should be tempered. For reliable, proven snoring reduction, a mandibular advancement device remains the gold standard. Asonor works best as a complementary solution — or as a low-commitment first step for mild snorers.
Frequently asked questions
Does Asonor anti-snoring spray actually work?
According to Asonor's own clinical studies, 3 out of 4 users reported reduced snoring. The spray works by lubricating and tightening the throat tissue, reducing the vibrations that cause snoring. Results vary — it works best for mild to moderate throat-based snoring.
How do you use Asonor spray?
Tilt your head back and pump 4–5 drops into each nostril just before bed. The solution travels from your nasal passages to the back of the throat where it coats and tightens the soft tissue. Avoid swallowing, eating, or drinking after application.
Is Asonor safe to use every night?
Yes. Asonor is formulated with gentle, non-medicated ingredients and is designed for nightly use. It's not a pharmaceutical drug, so there are no dependency risks. However, if you have nasal conditions or allergies, consult your GP first.
How long does a bottle of Asonor last?
A single 30ml bottle typically lasts 2–4 weeks depending on usage. At 4–5 pumps per nostril per night, most users get about 25–30 nights per bottle.
How does Asonor compare to other anti-snoring sprays?
Asonor targets the throat (via nasal application), which is unusual for a spray. Most anti-snoring sprays are either decongestant nasal sprays or throat sprays. Asonor's approach is unique but has a more limited evidence base than mechanical devices like mouthpieces.
