At SleepTest.com, better sleep starts with better breathing. That's why we recommend SONU Band - a drug-free wearable that helps relieve nasal congestion so you can breathe easier at night.
At SleepTest.com, we help people get to the root of their sleep issues. Sometimes poor sleep is tied to sleep apnea. Sometimes nasal congestion, allergies, or restricted nasal breathing are making sleep worse.
SONU Band is a product we recommend because it offers a non-drug option for people struggling with nasal congestion at home. It aligns with our belief that better breathing can support better rest — and that patients deserve practical solutions, not guesswork.
Drug-Free Relief
SONU uses acoustic therapy, not medication or steroids.
At-Home Convenience
Easy to use from home and designed to fit into a nightly routine.
Sleep-Focused
We recommend solutions that support better breathing and better rest.
When your nose feels blocked, sleep can suffer. Congestion may lead to mouth breathing, more nighttime wakeups, worse snoring, and an overall drop in sleep quality. SleepTest.com has also noted that allergies and congestion can worsen sleep apnea-related symptoms in some people. SONU is not a sleep apnea test or a sleep apnea treatment — but for people whose nights are disrupted by nasal congestion, it may help support easier breathing and a more comfortable night’s sleep.
SONU Band is designed to relieve nasal congestion using personalized acoustic resonance therapy through a comfortable wearable band.
According to SoundHealth, SONU has been studied in a randomized controlled trial and shown to improve nasal symptoms such as congestion, itching, and runny nose. The company highlights a 2x improvement in nasal congestion symptoms compared with placebo and says over 80% of patients experienced a clinically significant reduction in congestion symptoms. SoundHealth also cites physician support and notes that SONU was recognized as one of TIME’s 2025 Best Inventions.
If nasal congestion is your main issue:
SONU may help you breathe more comfortably and support better sleep at home.
If you also snore, wake up tired, or feel exhausted during the day:
You may need more than symptom relief. SleepTest.com can help you find out whether sleep apnea is part of the problem with an easy at-home sleep test. SleepTest highlights snoring, gasping, headaches, daytime sleepiness, and low energy as common warning signs.

No. SONU is indicated for relief of moderate to severe nasal congestion due to allergic and non-allergic rhinitis. It is not a sleep apnea test or sleep apnea treatment.
According to SoundHealth, SONU is for individuals 12 and older with moderate to severe nasal congestion related to allergic or non-allergic rhinitis.
That may be a sign that congestion is only part of the issue. SleepTest.com recommends considering an at-home sleep test if you also have snoring, gasping, headaches, or daytime fatigue.
