Your Inhaler Treats Half Your Airway — SONU Band | SoundHealth

Living with asthma

Your inhaler treats half your airway.

Asthma is a one-airway disease — nose to lungs, inflamed together. Up to 4 in 5 people with asthma also have rhinitis at the top of that airway. Research links treating it to about half the risk of asthma-related ER visits. Sonu is the drug-free, FDA-cleared way to take the top half back.

🫁

Your inhaler stays. Sonu is not an asthma treatment — it treats the rhinitis most asthmatics also carry. Keep following your asthma action plan.

The unified airway

Asthma is a one-airway disease.

Doctors call it the unified airway: your nose and lungs are one continuous passage sharing the same inflammation. When the top is blocked, you mouth-breathe cold, dry, unfiltered air straight to lungs that are already touchy — all day, and all night. That's why the nose is where airway doctors look first in their asthma patients.

Your inhaler's job

Bronchodilators and inhaled steroids — prescribed by your doctor, guided by your action plan. Nothing here changes.

Sonu's job

The congestion, drip, itch, and sneezing of rhinitis — cleared with drug-free acoustic resonance, no additions to the med list.

The evidence

What asthmatics deserve to know

4 in 5

Asthma rarely travels alone

Roughly 80% of people with asthma also have rhinitis — in some clinic studies, over 90%. Having both typically means more severe, harder-to-control disease. Yet the nasal half often goes untreated.

Treat the rhinitis, and asthma outcomes look different

In patients with both conditions, those treated for their rhinitis had about half the risk of an asthma-related ER visit or hospitalization (IDR 0.49, p=.001). A second study found nasal anti-inflammatory users had significantly lower odds of asthma ER care (OR 0.75) and hospitalization (OR 0.56). These studies reflect rhinitis treatment generally — not the Sonu device.

2–18

It holds for kids and teens too

In a cohort of asthmatic children ages 2–18, adequately treating their allergic rhinitis was associated with a lower incidence of acute asthma exacerbations. The unified airway doesn't wait for adulthood — and Sonu is FDA-cleared for ages 12 and up.

Sept

And the timing is now

September brings more asthma-related ER visits than any other month in the U.S. — the AAFA's "September Asthma Peak" — followed by cold, dry air through fall. The half of the airway you can calm today is the top one.

Where Sonu fits

The nasal half, without another drug

Until now, treating rhinitis meant adding to the med list — usually a daily steroid spray. Sonu is the only FDA-cleared wearable with an indication comparable to a nasal steroid spray: AI-personalized acoustic resonance that relieves congestion, runny nose, itching, and sneezing. Zero pharmacology. Zero interactions with what you already take.

Scan your face

The app maps your nasal anatomy in seconds and tunes your frequencies to it.

Wear the band 15 minutes

Gentle acoustic vibrations resonate through the sinuses — most people find it deeply relaxing. Before bed works beautifully.

Nasal breathing, restored

In its RCT, Sonu reduced total nasal symptom scores 2× better than placebo, with an 81% response rate.

Who this is for

Built for the way asthma actually lives

Adults managing asthma

You've handled the bottom half for years. This is the first drug-free tool for the top half of the same airway.

Parents of teens 12+ on inhalers

Many teens are already on two steroids a day — inhaled plus nasal. Sonu gives the nasal half a drug-free option, FDA-cleared for ages 12+. Talk to your doctor before changing anything.

Anyone tired of adding medications

Controller, rescue, antihistamine, spray, tablet… Sonu is the one item on the shelf that isn't a drug — nothing to metabolize, nothing to interact.

Sonu is FDA-cleared to treat nasal symptoms of allergic rhinitis (nasal congestion, runny nose, nasal itching, sneezing) in people ages 12 and up. Sonu is not indicated to treat, prevent, or manage asthma and is not a substitute for any asthma medication. Do not change your asthma medications without consulting your physician; always follow your asthma action plan.
