Many sleep specialists hesitate to prescribe a heated humidifier for CPAP therapy – and for good reason. When the water chamber isn’t emptied and cleaned daily, it becomes a breeding ground for bacteria, mold, and viruses. A 2015 survey found that nearly 60% of CPAP users skip daily cleanings, and over 25% clean their humidifier only a few times per month. That moisture buildup directly translates to harmful microorganisms being delivered into your airway each night.
Risks of Neglecting Your CPAP Humidifier
-
Bacterial and Fungi Growth: Excess moisture fosters pathogens that can cause bronchitis, respiratory infections, and allergic reactions.
-
Mold and Algae: Unchecked, these organisms release spores that irritate lungs, eyes, and sinuses.
-
Mineral Deposits: Tap water’s minerals accumulate in the chamber, creating “gunk” that harbors germs and degrades performance.
Federal agencies like the EPA and Consumer Product Safety Commission warn that contaminated humidifiers pose serious health risks. Regular maintenance drastically reduces your exposure to these threats.
Best Practices for Your CPAP Humidifier
- Use Distilled Water OnlyTap water contains chlorine, pollutants, and minerals that promote scale and microbial growth. Distilled water keeps your humidifier chamber clean and extends its lifespan.
- Clean DailyAfter each night’s use, discard remaining water and rinse the chamber with warm, soapy water. Disinfect Weekly: Soak in a 1:3 vinegar-to-water solution for 15–30 minutes, then rinse thoroughly.
- Inspect for Wear
Check seals, tubing, and the water chamber for cracks or cloudiness. Replace parts per manufacturer guidelines—typically every 6–12 months.

Avoid Common Pitfalls
-
No Household Humidifiers: Portable room humidifiers are not designed for CPAP machines and can introduce airborne contaminants.
-
Skip Harsh Chemicals: Stick to mild dish soap or vinegar; bleach and alcohol can damage seals and plastic components.
A well-maintained CPAP humidifier ensures therapeutic air quality, protects your health, and preserves the functionality of your equipment. Make cleaning and using distilled water a non-negotiable part of your nightly routine – your lungs will thank you.
