CO2 can be toxic at high levels, particu-
larly if you have breathing issues. CO2
is the focus of the Laser Egg+ CO2 air
quality monitor. The HomeKit-compati-
ble device’s readings follow U.S.
Environmental Protection Agency
standards. CO2 and Total Volatile
Organic Compounds levels are dis-
played as parts per million and PM2.5
as micrograms per Cubic Meter of Air
(μg/m3). Air Quality Indexis displayed as
a numerical value corresponding to one
of six color-coded categories repre-
senting the current level of health
concern.—MICHAEL ANSALDO
