Why monitor
Better air, better days
Every room, at a glance
Fresher workspaces
Busy rooms get stuffy. Live CO₂ readings show when a work or study space needs fresh air.
Spot particle spikes
Cooking, candles and outdoor smoke can raise fine particles indoors. Particle monitors show the change as it happens.
Ventilate at the right time
Example: a bedroom overnight, with a window opened at 05:00.

From pocket-size CO₂ checkers to 10-in-1 stations that track particles, gases and climate.
How it works
From sensor to insight

-
Check it from your phone
Wi-Fi models pair with a phone app, so you can see your rooms when you're away.
For every space
A monitor for every room

Getting started
Cleaner air in three steps
-
Choose what to measure
CO₂ for stuffiness, particles for smoke and dust, or an all-in-one for the full picture.
-
Place it where you breathe
At head height, away from windows, vents and direct sun, in the room you use most.
-
Act on the readings
When CO₂ climbs past about 1,000 ppm, open a window or turn up ventilation.
