CPAP Humidifiers

CPAP humidifiers improve therapy comfort by adding moisture to the pressurized air delivered by the CPAP device. They are particularly helpful in cases of nasal dryness, dry throat, irritation or congestion.

When properly adjusted, a CPAP humidifier helps users better tolerate therapy, reduces nighttime awakenings and encourages consistent CPAP use.

What is a CPAP humidifier used for?

A CPAP humidifier adds moisture to the airflow to prevent drying of the nasal and throat tissues. It improves breathing comfort and can reduce common CPAP-related side effects.

It is often recommended when indoor air is dry, during colder seasons, or for users prone to nasal irritation.

How does a CPAP humidifier work?

A CPAP humidifier uses a water chamber to humidify the pressurized air. Depending on the model, the water may be heated to increase humidity levels and enhance comfort.

Some systems combine the humidifier with a heated CPAP hose to reduce condensation inside the tubing (rainout).

What types of CPAP humidifiers are available?

CPAP humidifiers generally include:

• integrated humidifiers: built into certain CPAP devices,
• heated humidifiers: with adjustable humidity and temperature settings,
• water chambers: replacement reservoirs essential for humidification.

Why use a CPAP humidifier?

Adding humidity can help reduce:

• nasal and throat dryness,
• irritation or burning sensations,
• nasal congestion,
• discomfort caused by high air pressure.

Improved comfort often leads to better therapy adherence and more effective treatment outcomes.

How to choose a CPAP humidifier?

When selecting a CPAP humidifier, it is important to check:

• compatibility with the CPAP device brand and model,
• water chamber type and availability,
• heating function and adjustable settings,
• compatibility with heated tubing if needed.

Proper humidity adjustment is essential to avoid excess moisture and condensation in the tubing.

Frequently asked questions about CPAP humidifiers

Is a CPAP humidifier necessary?
Not always, but it is strongly recommended for users experiencing dryness, irritation or nasal congestion.

Why is there water inside my CPAP hose?
This is usually caused by condensation (rainout), often due to cool room temperatures. Proper settings and/or heated tubing can help prevent it.

What type of water should be used in a CPAP humidifier?
It is generally recommended to use water according to the manufacturer’s guidelines to prevent mineral buildup and protect the water chamber.
