Is the A.I.R. device user exposed to UV light?

Updated: Sep 30

Answer: No


Testing has shown that the person wearing the AIR Device (aka AIR Solo) is not exposed to any detectable level of UV exposure while using the device. Tests conducted include using an ultraviolet sensor to measure any UV light reflected or directed back into the direction of the user. The results showed no measurable amount of UV light was detected by the sensor when positioned in the face opening of the prototype model.

Update:

Tests conducted include using a UV sensor to measure any UV reflected back to the user. Tests conducted include using an ultraviolet sensor to measure any UV light reflected or directed back into the direction of the user. The results showed no measurable amount of UV irradiation was detected by the sensor when positioned in the face opening of a test head analog.

Additional Testing:

Using a UVC Radiometer placed the the airway opening of the device, the sensor is positioned to detect any UVC directed towards the user. As with the previous tests, the results showed no measurable amount of UV irradiation was directed towards the user.

Additional Testing: Update #3

Using more sensitive equipment which measures peak UVC output you can see that the device puts out a total of 40,000.0uW/cm2 - 45,000.0uW/cm2 UVC exposure. The sensor reading peak exposure from the user side of the device receives 0000.4uW/cm2 or 0.000001% of the irradiation.

Additional Notes:

As demonstrated the Solo irradiates approximately 40,000.0uW/cm2 - 45,000.0uW/cm2 UVC forward dosage but it should be noted that this forward irradiation does not expose others to UVC light. This is because the diffuser lens and user's mask both disperse and absorb the UVC irradiation as designed. The photo below demonstrates this.
