Person suffering from wildfire smoke pollution indoors — Airthings View Plus monitors PM2.5 to track wildfire smoke infiltrating your home

Wildfire season

Wildfire smoke doesn't stop at your front door

PM2.5 particles from wildfire smoke are small enough to slip through windows, vents, and door seals — and small enough to reach deep into your lungs. Track real-time levels with View Plus, then let Renew automatically clear the air when smoke spikes.

Protect against wildfire smoke How smoke gets inside

EPA AirNow lists PM2.5 above 35.4 µg/m³ as unhealthy for sensitive groups. Indoor levels can climb fast during nearby wildfire events.

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.

“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.”
