Why Multiroom Monitoring?

Every room hides a different risk

Air quality threats vary room by room — and floor by floor. One monitor placed in one spot can never give you the full picture of your home.

Airthings multiroom air quality monitoring — devices across bedroom, basement and living room
Bedroom — CO₂ while you sleep
CO₂ naturally rises overnight in closed rooms, disrupting deep sleep and leaving you groggy. Monitoring here helps you wake up genuinely refreshed and focused.
Basement — radon is the silent threat
Radon seeps up from the ground and concentrates on lower floors. Completely odourless and invisible, it's the #1 cause of lung cancer among non-smokers.
Living room — your holistic air hub
VOCs from furniture, PM2.5 from cooking, humidity swings — your main living space is where it all converges. Get the broadest view of your family's daily air health.
Home office — stay sharp all day
Poor ventilation and rising CO₂ in a home office directly reduce cognitive performance. Know when to open a window before your productivity quietly suffers.

“Excellent Monitor and Great Company! I bought this because I have worked from home for 5 years, and I am in the basement of my home which had a Radon system in it when I bought the house. ”

“Provides a lot of data. This thing does a lot! You'll need a smart phone and the app to get things going. Install it and wait a week so it can calibrate. Then you're off and running and able to see all kinds of interesting data about the air quality of your house.”
