The answer.
No. ALEX does not diagnose, treat or prevent medical conditions. Keep certified smoke and carbon monoxide alarms installed and maintained. ALEX is not a substitute for either, or for advice from a healthcare professional.
A little more context.
We want the limits of ALEX to be as clear as its intended use. Information about indoor air is not a diagnosis, and it does not establish that a home is free from every possible hazard.
If you have a health concern, speak to a qualified healthcare professional. For emergency alarms, follow the instructions for your certified smoke and carbon monoxide alarms.
