Radon awareness

Multi-room radon protection

Radon levels can vary significantly from one floor to the next. With the View Plus Duo, you can monitor the two highest-risk areas of your home simultaneously.

Radon is a naturally occurring gas that enters through cracks in the foundation. By placing monitors in different rooms, you can identify hidden risks exactly where they exist.

The View Plus Duo ensures no room is left a mystery.

Health impact

Double the data for localized peace of mind

Radon is the second leading cause of lung cancer. Since levels fluctuate daily, long-term monitoring in the rooms you use most is essential.

By placing one View Plus in your living area and another in a bedroom, you get a 24/7 map of your home's safety where it matters most.

Continuous, room-by-room data. One unified app.

Know exactly where to place each monitor

Position one View Plus where your family spends waking hours, and the other where you sleep. The Airthings app connects both, surfacing how air quality shifts between the two spaces across the day.

Bedroom
Captures overnight CO2 and radon accumulation — the data most closely linked to sleep quality and long-term health.
Living room or kitchen
Monitors daily pollutants from cooking, cleaning products, and outdoor air — where most waking hours are spent.
