Product description

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:


Better together.

At home or on the go, pair your Laser Egg with the Kaiterra app for greater convenience, more control. View home and local air quality readings with just a tap.


See historical graphs by minute, hour or day. And make smarter decisions for your home that last.


A smarter, cleaner home.

The Laser Egg 2 supports Apple HomeKit technology and soon, IFTTT, to safely and seamlessly work with your home’s appliances. No more worrying about when to turn on your air purifier if the air pollution spikes. Or let your humidifier take over if the air becomes too dry. A connected ecosystem for a protected home and peace of mind.
