Protect the air you breathe.
The world’s most popular smart air
quality monitor with high accuracy
PM2.5 detection.
Make your home an oasis.
What we can’t see can still harm us. Dust, PM2.5 smoke, and other particles constantly affect the air in your home. The Laser Egg 2 tells you instantly and accurately what’s in the air, so that you can make sound 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:
