If you're new to CPAP therapy, you've likely heard about humidifiers but may be wondering if one is necessary. For many users, especially those new to CPAP therapy, a humidifier can be what helps them stick with their therapy consistently.

In this beginner’s guide, we’ll break down what CPAP humidifiers do, why they matter, and how to choose the right one for your needs.

What Is a CPAP Humidifier?

When we breathe naturally, our noses humidify and warm the air. However, CPAP machines push air through your airway faster than your nose can handle — especially in dry or cold environments.

That may lead to discomfort and potential health issues that can cause new patients to stop their therapy.

That’s where humidifiers come in; they replicate your nose’s natural function by adding moisture to the air delivered by your CPAP machine to help prevent common conditions such as:

  • Dry mouth and throat
  • Nasal congestion
  • Nosebleeds
  • Sinus irritation
  • Chapped lips

Types of CPAP Humidifiers

CPAP therapy generally relies on one of three different types of humidifiers:

  • Built-in humidifiers: Integrated into the CPAP machine and ready to use.
  • Integrated humidifiers: Attach to compatible machines and can be removed for travel.
  • External humidifiers: Standalone units that connect to any CPAP machine.
The majority of modern CPAP machines, like those offered at NuCara Home Medical, feature built-in or integrated humidifiers for convenience and performance.

Why You Might Need One

Humidifiers can be especially helpful if you:

  • Experience dryness or irritation during therapy
  • Use higher pressure settings
  • Sleep in a cool or dry room
  • Have allergies or sinus issues
  • Are new to CPAP and struggling with comfort
Studies have shown that adding a humidifier can significantly improve your therapy experience and increase your likelihood of sticking with long-term treatment.

Common Issues: What Is “Rainout”?

Rainout is the buildup of condensation in your CPAP tubing or mask, often caused by warm, humidified air cooling in the hose. It can lead to:

  • Water splashing on your face
  • Gurgling noises
  • Interrupted sleep

How to Prevent Rainout

  • Use heated tubing to maintain consistent air temperature
  • Adjust your humidifier settings to match room conditions
  • Insulate your tubing if needed
NuCara offers heated tubing and accessories designed to eliminate rainout and keep your therapy smooth and uninterrupted.

Do You Really Need One?

CPAP humidifiers may not be strictly necessary, but adding one can make a big difference in your comfort level and compliance with therapy. If you’re experiencing dryness, discomfort, or trouble sticking with therapy, a humidifier might be the solution.
