Phare is a smoke alarm that uses indoor air quality (IAQ) sensors to better discriminate between fires and nuisances, and provides you with tailored actionable IAQ insights. It brings together the smoke alarm and the air quality monitor into a single device to bring safe, healthy air to your home.

Today’s smoke alarms are inaccurate and inadequate. They miss 43% of fires, have a 75% false alarm rate, and ignore all other pollutants in the air other than smoke. The last significant improvement in smoke detection technology dates back to 1973. Current photo-electric sensors look for smoke, but most can’t distinguish it from steam, dust, and other harmful particles. This is particularly concerning as we spend 90% of our day indoors, unknowingly breathing air that is 2 to 5 times dirtier than outdoor air.

Phare complements the current optical smoke sensor data with indoor air quality data, looking at the air composition and using machine learning to understand which is the source of the pollutants in it. This allows us to give you tailored actionable insights on what you can do to boost your health, well-being and productivity while keeping you safe.
