It’s easy to take control of your air.
The world’s most popular smart air
quality monitor, now with high
accuracy PM2.5 and TVOC detection.
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.
Find the indoor pollutants in your home.
Harmful VOCs (volatile organic compounds) are organic, evaporative chemicals commonly found around the home, in building and furnishing materials, including paint, wood and particleboard.

A metal–oxide–semiconductor in the Laser Egg 2+ is used to measure TVOC levels and track down the invisible pollution in your home.

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:

Multiple pollutants, one simple view
In addition to individual measurements, the Laser Egg 2+ can display your home’s air quality with the Overall Index - uniquely developed by Kaiterra to combine readings of PM2.5 and TVOC concentrations.

Created to offer the most complete air quality reading in one easy-to-read display.

Learn more about the Overall Index here.

The overall index can incorporate national AQI standards from a variety of countries in the PM2.5 calculation. You can use the Kaiterra app to select which standard to use.
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.
