    Search “myAir” in the App Store or on Google Play to download the app to your phone. If you already have a myAir account, you can sign in directly with your username and password. If you’re a new user, click “Create account” and fill in the required fields.

  • Activate your account
    You should receive an email from myAir asking you to activate your account. Click on the link in the email, then follow the prompts to create your password. To access myAir, you must enter your log-in information and then enter a one-time passcode that is sent by email.

Attaching the air tubing

Connect your air tubing by holding the cuff and lining it up with the connector port on the back of the machine. Line up the connector pin on the tubing cuff to the corresponding slot on the connector port. Push until the cuff clicks into place.

Installing the water chamber

Open the lid of the water tub and fill it with drinking-quality water (for cleanable tub) or distilled (for standard tub) up to the maximum water level mark. Close the lid and gently push the water tub into the side of the machine until you feel it lock into place.

Fitting your mask

The myAir app offers step-by-step instructions to help you fit your mask and check the seal. You can also follow the steps below:  

  • With your mask on your face, connect the tube from your machine to your mask
  • On the Home screen, select “MORE” and then under “THERAPY”, tap the Mask Fit option and select “START” 
  • The machine will start blowing air and a green tick will automatically appear on the screen
  • Wait a few seconds while the machine checks your mask fit
  • If the green tick changes to an orange exclamation mark, your mask may be leaking and you might need to make small adjustments to the fit
  • Readjust the top and bottom headgear straps so that your mask fits snugly but is not pulled tight. You can also pull the mask away from your face and gently let it fall back against your skin
