BreathTech-S³ - What does my data mean?


Indicates the cumulative wearing time of the mask. Data will be captured when the mask is in the loose or fitted state and the sensor is on and paired with Bluetooth. When the mask is not in use, please remember to switch off the sensor by pressing and holding the power button until the red light appears.


Will show as ‘fit’ or ‘loose’. A notification will be displayed if your mask is loose and you need to wear your mask or if you forget your mask.  The mask fit status will take 30-60 seconds to update as the app needs to eliminate the possibility of displaying an inaccurate fit status based on slight adjustments to the mask by the user.


Shows the % remaining lifetime of the mask and will decrease with continued usage.  A notification will be displayed when you need to clean the mask. At this time, you may wash and re-scan your mask or scan and use a new mask. At the end of the lifetime of the mask a notification will guide you to responsibly dispose of the mask in a sustainable manner.


Shows the number of breaths per minute. High breathing rates could be an indication of a respiratory-related illness. This product is not intended for medical purposes. 


A high carbon dioxide build up could lead to Hypoxia which is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. When the mask air quality is shown as ‘bad’ or as when a notification is displayed “To take a breath of fresh air” please remove the mask in a safe environment and take a fresh breath of air and wear your mask again. This product is not intended for medical purposes. 

Important Notes


  • The sensor must be switched on and paired to your phone to capture data. To switch on press and hold the power button until the green light is shown. To switch off press and hold the power button until the red-light flashes and the sensor powers off. 

  • If the mask is not actively used for an extended period of time, please switch off the sensor.  

  • The Incorrect placement of the sensor will impact the data displayed. The sensor should be placed so that humidity from the nostrils are captured as per the on-screen instructions.  

  • The sensor uses a CR1220 battery. Please insert the batteries for first use and when the batteries have drained. 

  • The data captured will be inaccurate if you are holding your breath when the body is in a state of rest where oxygen intake is reduced or for those with extremely low exhalation patterns. The sensor captures data based on the humidity buildup through inhalation and exhalation. 

  • The sensor should be used carefully and not physically damaged. The manufacturers are not responsible for any damages caused by misuse of the product. 

  • The sensor should be removed when washing the mask.
