Overview

This replacement humidifier water chamber is compatible with the Luna II CPAP Machine. It is designed to be accessible and easy to use with a front cap to easily fill up and a label with a Max fill-up line.

Replaced every 6 months to avoid the chamber to become cloudy or even pitted due to the mineral levels found in most tap and drinking water. As the material deteriorates, invisible cracks may trap bacteria from moisture.

Why do CPAP machines have humidifiers?

CPAP humidifiers add moisture to prevent dry mouth, throat irritation, and nasal congestion caused by pressurized air.

Are all CPAP humidifiers the same?

No, there are two types: - Integrated humidifiers (built into the CPAP machine) - Standalone humidifiers (separate units that connect to the CPAP)

Do I have to use a CPAP humidifier?

No, but it helps reduce dryness and discomfort. If you experience dryness, adding a humidifier can improve comfort.

What type of water should I use in my CPAP humidifier?

Use distilled water to prevent mineral buildup and bacteria growth. Avoid tap or bottled water.

How often should I clean my CPAP humidifier?

Daily: Empty and rinse with warm water. Weekly: Wash with mild soap, rinse well, and let it air dry.

Why is there water in my CPAP mask or hose?

This is rainout, caused by humidified air cooling in the hose. Using heated tubing or a hose cover can help.

Can I travel with a CPAP humidifier?

Yes, but some travelers prefer to turn off the humidifier to reduce bulk. If flying, empty the water chamber before packing.

When should I replace my CPAP humidifier chamber?

Every 6 months, or sooner if you notice discoloration, cracking, or buildup that doesn’t clean off.
