HumidX F20 AirMini Waterless Humidification

The HumidX F20 is a small heat and moisture exchanger (HME) designed to provide comfortable and effective humidification without water. When users breathe, heat and moisture from every exhale are captured and stored within the HME's tiny paper ridges before it reaches the mask's vent.  When they inhale, this heat and moisture are released into warm and comfortable air during the night.


The HumidX F20 humidification system is only compatible with AirFit F20 and AirTouch F20 Masks for AirMini travel CPAP machines. 

HumidX F20 Capsule
This is the standard waterless humidification system for most climates and sleep environments.

How Does It All Work?

As patients breathe, heat and moisture from every exhale are captured and stored within the HME’s tiny paper ridges. When they inhale, this heat and moisture are released to provide warm and comfortable air throughout the night

Technology Reinvented

Some hospital devices have been using waterless humidification for over 50 years. What sets ResMed’s HumidX apart from other CPAP waterless humidification solutions is that it passes air through an exchange before it reaches the mask’s vent. In doing so, heat and moisture loss is minimized.

It's a MIRACLE!!! I purchased the AirMini with the expectation that I would be able to use the waterless HumidX system. Of course, the regular HumidX only works with the N20 and P10 ResMed masks. BIG problem for those of us who use the ResMed Full face masks, and BIG DISAPPOINTMENT! The technician who was helping me get fitted for a new mask told me he thought ResMed was working on a system to use with the full face masks. He called me later and told me he found it available on the internet. Lo and behold, I found it online with RespShop! HumidX F20 is a miracle that snaps right into my AirTouch F20 mask. It will also work with the AirFit F20. There is not yet a HumidX for the F30 mask, but I hear they are working on it. I'm sure you'll be able to find it HERE on once it does become available. Thank You RespShop!!!

What causes the VERYunpleasant smell from the HumidX F20 humidifier?
After the first night of using a new cartridge recently, I woke with vertigo which lasted about 1 hour. I am very concerned about the possible damage these chemicals may be doing to my brain/ other organs. How can I avoid this smell? I have tried opening the packet 24 hours before installation but this does not help. I look forward to your reply. Yours faithfully, Dr Robyn Denner.
Hi there, I am sorry that you are experiencing an unpleasant smell from the HumidX. Some people appear to be more sensitive to it than others. You may want to consider running the device without wearing it for a few hours to see if that will get rid of the smell. You may need to turn the Auto OFF function off to do this. I have ResMed's phone number here if you would like to inquire with them for other options: 1 800-424-0737
