Who is Lumen for?

At this time, Lumen was designed to be used by individuals who are 16+ and considered healthy.
For individuals who have been diagnosed with or have the following conditions:
Severe COPD
Severe asthma
Clinically Obese
Lumen is not right for you and we recommend that you do not purchase the device.
If you are currently under medical supervision for an autoimmune disorder/condition or other health-related matters, please consult your doctor before purchasing Lumen. If you have further questions about the science behind Lumen, you can visit our help center HERE.

Can multiple people share one device?

Lumen is designed to be used by one individual at a time. While it is possible for two people who live in the same home to share a single device, we do not recommend it for a number of reasons:
1. Each user will need to download the Lumen App separately to their phones and create their own profiles.
2. In order to unlock your day and receive your meal plan, you'll need to complete a morning breath measurement.
3. Sharing a device makes it difficult to use Lumen consistently on a daily basis, leading to lower rates of success in reaching health goals. Our testing shows that users who use Lumen throughout the day are statistically more likely to succeed in their goals.
