Meet the world’s most popular smart air quality monitor: the Laser Egg 2.

Laser Egg Air Pollution Monitor

The Laser Egg 2 tells you instantly and accurately what is in the air you’re breathing, so that you know whether or not you efforts to keep your environment clean and healthy are working. Backed by Smart Air’s open-data tests, the Laser Egg has high levels of accuracy when measuring PM2.5.

A small fan pulls ambient air in through the back of the unit and pushes it out the front. In the middle, a laser beam cuts across this air current. As particles pass through the laser beam, the beam’s light is refracted. A sensor picks up the subtle changes, and information about the size and number of particles passing through is determined through a series of algorithms.

Laser Egg Air Quality Monitor smart device

Provides air quality readings in real-time; measurements are taken every 0.1 seconds and displayed on the LCD screen. Air quality can be displayed as PM2.5 concentration, AQI (US EPA & Chinese standards), and particle count.

An embedded Lithium ion battery means that you can take the Laser Egg 2 around with you, wherever you go. The battery lasts for approximately 8 hours on a full charge. Or you can leave it at home, plugged in and recording data, 24/7.
