Overview

Specifically designed for the AirMini™ travel CPAP machine and AirFit/AirTouch F20 full-face masks, these compact waterless humidifiers capture heat and moisture from every breath you exhale, releasing it back as you inhale. This keeps your airways moist, reduces dryness, and provides an easy-to-use, portable option without the distilled water or power. 

Available in packs of 1, 3, or 6, each HumidX™ cartridge should be replaced every 30 days for optimal performance.

Product Features

Waterless Humidification

The HumidX™ cartridges use Heat Moisture Exchange (HME) technology to provide humidification without using distilled water or electricity. This approach captures heat and moisture from your exhaled breath and returns it upon inhalation for comfortable and moist air during your CPAP machine use.

Designed for F20 Masks

These HumidX™ cartridges are exclusively compatible with the AirFit™ F20 and AirTouch™ F20 full-face masks. They are tailored to fit perfectly with these masks when used with the AirMini™ travel CPAP machine, ensuring seamless integration and reliable performance.

Perfect for On-the-Go

If you're traveling or just want a low-maintenance setup, HumidX™ F20 cartridges are a simple way to keep things comfortable—no need for distilled water, water chamber or extra gear.

Easy to Use and Replace

HumidX™ F20 cartridges are all about ease. Just slip them in between your mask and the tube connector—it’s pretty straightforward. They’re good for up to 30 days, and changing them out doesn’t take much effort.

Travel Friendly

HumidX™ F20 cartridges are lightweight and small enough to fit in your hand, making them great for travel. They keep things simple—no bulky water chambers or extra humidifiers needed—so you can easily take them along wherever you go.

Hygienic Disposable

HumidX™ cartridges are disposable, which keeps your CPAP setup clean by reducing the chance of bacteria and mold building up. Just swap out each cartridge every 30 days to keep things fresh and ensure your therapy stays effective.

Moisture for Comfort

HumidX™ cartridges help keep things comfortable by adding moisture to the air you breathe, easing issues like dry mouth, sore throat, and stuffy nose. This can make sticking with your CPAP therapy a lot easier and more effective over time.

Pack Options

​​HumidX™ cartridges come in packs of 1, 3, or 6, so you can choose what works best for you. Whether you want to stock up or just have a few extras handy, there's an option to fit your needs.

Important Tips

  • Store HumidX cartridges in a cool, dry place to maintain their effectiveness and avoid exposure to moisture or extreme temperatures
  • Test the HumidX cartridge setup before your trip to ensure it fits correctly and functions well with your AirMini CPAP and mask.
  • Check the HumidX cartridge for any signs of wear or reduced performance; replace sooner if it seems less effective.
  • Use a case for the AirMini and HumidX cartridges when traveling to prevent damage or contamination.
  • Replace the cartridge after 30 days of use even if it appears clean, as its moisture-retaining properties will degrade over time.
  • Keep a small supply of HumidX cartridges in your travel bag or bedside drawer to ensure you're always prepared for your next trip or replacement.

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.
