For those who rely on a Continuous Positive Airway Pressure (CPAP) machine to treat sleep apnea, the benefits of consistent use are undeniable. CPAP therapy ensures your airway stays open, promoting uninterrupted sleep and reducing health risks associated with obstructive sleep apnea.

While the focus often lies on the machine’s settings or mask fit, one critical yet frequently overlooked component is the water used in the machine’s humidifier. Specifically, distilled water is recommended. And for good reason. Let’s explore why using distilled water for a CPAP machine is essential and how it contributes to the overall effectiveness of your CPAP therapy.

What Role Does Water Play in a CPAP Machine?

Modern CPAP machines have a humidification chamber that adds moisture to the air delivered through the mask. This feature helps prevent dryness and irritation in the nasal passages, mouth, and throat, making the therapy more comfortable and sustainable for long-term use.

The type of water you use in the humidifier is more than a trivial choice. While tap water might seem like a convenient option, it can lead to several issues that compromise both the machine’s performance and your health. Distilled water, on the other hand, ensures optimal operation and hygiene. Here’s how.

Prevents Mineral Buildup

Tap water contains minerals like calcium, magnesium, and other impurities. When this water is heated in your CPAP’s humidifier, these minerals are left behind as residue.

Over time, this buildup can clog the humidifier chamber, reduce its efficiency, and even cause damage to the heating element. Distilled water is free of these minerals and prevents this problem entirely.

Protects Against Bacteria and Mold Growth

Tap water and even bottled water often contain trace amounts of bacteria and organic material. When these contaminants are heated and sit in the humidifier, they create an ideal environment for bacteria and mold to thrive.

Breathing in air exposed to these pathogens can lead to respiratory and other health problems. Distilled water eliminates this risk because it undergoes a purification process that removes all impurities, ensuring a clean, safe humidification system.

Enhances Machine Longevity

CPAP machines are an investment in your health. Proper maintenance is key to protecting that investment. The mineral deposits left by tap water not only damage the humidifier but can also affect other components of the machine. Using distilled water significantly reduces wear and tear, extending the life of your CPAP machine and saving you money in the long run.

Ensures Consistent Humidification

Mineral deposits and impurities can interfere with the humidification process, leading to inconsistent moisture levels in the air delivered by your CPAP machine. This can result in discomfort, dryness, or irritation. Distilled water provides a consistent, clean source of moisture, ensuring your therapy remains effective and comfortable.

Risks of Using Non-Distilled Water in Your CPAP Machine

Despite the clear benefits of distilled water, some CPAP users opt for alternatives like tap water, filtered water, or spring water, often due to convenience or cost concerns. However, these choices come with risks:

  • Mineral Residue — As mentioned, non-distilled water leads to mineral buildup, which can compromise machine functionality and require more frequent cleaning or replacement of parts.
  • Health Hazards — Bacteria, mold, and other impurities in non-distilled water can pose serious health risks, particularly for individuals with compromised immune systems or respiratory conditions.
  • Higher Maintenance Costs — Frequent cleaning, repairs, or replacement of the humidifier chamber and other components can add up, making the use of non-distilled water a false economy.

Tips for Using Distilled Water Effectively

Now that you understand the benefits of using distilled water in your CPAP machine, here are some tips to ensure that you are using distilled water effectively.

  • Change the Water Daily — Distilled water should be replaced daily to prevent stagnation and ensure optimal hygiene.
  • Clean the Humidifier Regularly — Follow the manufacturer’s guidelines for cleaning the humidifier chamber to remove any potential residue or buildup.
  • Store Water Properly — Keep your distilled water in a clean, sealed container to avoid contamination.
  • Plan Ahead — Purchase distilled water in bulk or consider home distillation options to ensure you always have a supply on hand.
