5 Myths About Using a CPAP Machine
Key Takeaways
-
Modern CPAP machines like the AirSense 11 run around 27 dBA, quieter than a normal conversation.
-
Sleep apnea affects people across ages, body types, and genders, not just older, overweight men.
-
A 2026 study found CPAP use improved relationship quality for both patients and partners, sustained at 6 months.
-
CPAP masks include anti-asphyxiation valves that let you breathe room air if the machine loses power, there's no suffocation risk.
Quick answer: Most common CPAP fears, noise, bulky masks, relationship strain, are based on outdated technology from over a decade ago. Modern CPAP therapy looks and works differently than most people expect, and consistent use is linked to real health and relationship benefits, not the tradeoffs people fear.
Myth 1: "It Sounds Like a Jet Engine"
The reality: Modern machines are genuinely quiet. The ResMed AirSense 11, for example, runs at about 27 dBA, close to a whisper and well below normal conversation level. Most bed partners find it far less disruptive than untreated snoring.
Myth 2: "I'll Feel Like I'm Wearing a Gas Mask"
The reality: Mask design has changed significantly. Nasal pillow masks and minimal-contact full-face designs use soft silicone and under-the-nose seals, leaving a clear field of vision for reading or wearing glasses in bed. Tubing is lighter and more flexible than older designs.
Myth 3: "Only Older, Overweight Men Need CPAP"
The reality: OSA is influenced by anatomy and genetics, narrow airways or large tonsils, for example, not just age, weight, or sex. It affects younger adults, women, and even children, and is significantly underdiagnosed in women in particular, whose symptoms often present differently than the "classic" case.
Myth 4: "Skipping a Few Nights Doesn't Matter"
The reality: Even one night off CPAP reverses most of the sleep quality and alertness gains from treatment, with symptoms often returning almost immediately. Consistency, not occasional use, is what delivers the therapy's benefits.
Myth 5: "CPAP Will Hurt My Relationship"
The reality: The opposite tends to be true. A 2026 study of 54 couples found relationship quality improved significantly for both patients and partners after starting CPAP, with the improvement holding steady at 6 months.¹ On the sexual health side specifically, evidence is more mixed: CPAP is linked to improved sexual satisfaction in some studies, but it doesn't reliably raise testosterone, and its effect on erectile function varies across trials, it's not accurate to call untreated OSA "a leading cause" of ED outright.

Myth 6: "CPAP Machines Cause Sinus Infections"
The reality: The machine itself just moves filtered room air. Infections are almost always a maintenance issue, uncleaned equipment can harbor bacteria, which is why a regular cleaning routine matters. Properly maintained, a heated humidifier actually helps prevent the nasal and sinus irritation some people blame on the machine itself.
Myth 7: "If the Power Goes Out, I'll Suffocate"
The reality: CPAP masks include anti-asphyxiation valves and exhalation ports designed to open automatically if the machine stops delivering air, letting you breathe room air with no restriction. You might wake up because the airflow changes, but suffocation isn't a real risk.
