All-in-one device. Designed to help protect your air.

Every day, we take over 23,000 breaths. The air we breathe affects our health, sleep, and productivity. The Laser Egg 2+ tells you instantly and accurately what is in the air, so that you can make the right decisions to improve your environment.

Accurate, fast and reliable detection.

The Laser Egg 2+ uses laser-based light scattering to individually count particles in the air as they enter the device, and calculate PM2.5 concentrations based upon these measurements. This allows for extremely fast measurements, with high accuracy readings calculated every 0.1 seconds.

We take our air seriously. The Laser Egg has been carefully tested to ensure your home is protected. It can give particulate concentrations and AQI readings that fall within +/- 10% of the readings from the US Embassy in Beijing. See for yourself:
