What is the View Plus Duo?
The View Plus Duo is a two-pack of the Airthings View Plus monitor, designed to track indoor air quality in the two rooms where families spend the most time at home. Each View Plus uses seven sensors to detect radon, PM2.5, carbon dioxide, VOCs, humidity, temperature, and air pressure, with readings unified in the free Airthings app.
One monitor in the living room. One in the bedroom. One unified view of your home’s air.
Seven Sensors, Two Rooms
What does each View Plus monitor?
- Radon
- The top cause of lung cancer in non-smokers, according to the EPA.
- PM2.5
- Fine particulate matter from wildfire smoke, cooking, and candles.
- CO₂
- High indoor CO₂ impairs sleep quality and concentration.
- VOCs
- Airborne chemicals from cleaning products, paint, and new furniture.
- Humidity
- High humidity promotes mold growth and aggravates asthma.
- Temperature
- Affects sleep quality, mood, and alertness throughout the day.
- Air pressure
- Changes in air pressure affect radon levels and can trigger headaches in some people.
Why Two Monitors?
Does radon vary from room to room?
Yes — radon levels can differ significantly between floors and rooms within the same home, which is why the EPA recommends testing in the lowest lived-in level of the house. Radon is a naturally occurring radioactive gas that enters through cracks in foundations, floors, and walls, so concentrations typically build up first in basements and ground floors.
The View Plus Duo lets you continuously monitor two of those rooms at once. Pair one View Plus in a living area with another in a bedroom, and the Airthings app surfaces both readings on a single dashboard so you can see exactly where the risk is — and when it shifts.
According to the EPA, radon is the second leading cause of lung cancer in the United States, right after smoking, and the leading cause among non-smokers. It is colorless and odorless, so testing is the only way to know your levels.
Where to Place Each Monitor
Where should you put a View Plus?
Airthings recommends placing each View Plus in a room where the family gathers and spends time together — typically the living room and the bedroom for the View Plus Duo. Both rooms expose you to different air quality patterns across the day, and monitoring them together helps pinpoint where problems start.
- Living room or kitchen — daytime exposure
- The living room captures daytime pollutants from cooking, cleaning products, candles, and outdoor air entering through doors and windows. The Airthings View Plus tracks PM2.5, VOCs, and CO₂ here in real time.
- Bedroom — overnight sleep quality
- Bedroom CO₂ rises overnight in closed rooms and can disrupt sleep. The Airthings View Plus also tracks temperature and humidity, two factors directly tied to how well you rest.
- Basement or ground floor — radon entry point
- For homes in EPA Radon Zone 1 states, swap one monitor to the basement or ground floor — the level closest to the ground where radon enters first. The View Plus Duo is built to flex around your home’s layout.
Smart Hardware
What features does the View Plus include?
Each Airthings View Plus combines an always-on eInk display, flexible power options, and built-in hub connectivity in a single device. The design balances glanceable hardware at the wall with deeper insights inside the Airthings app.
- Customizable eInk display
- The Airthings View Plus has a low-energy eInk display that shows up to four of the sensor readings you check most often — always on, always readable, no tapping required.
- Battery or USB-C powered
- The View Plus runs cable-free on batteries for up to two years, or plugs in via USB-C for always-on power and hub functionality.
- Built-in Airthings hub
- Plug a View Plus into USB-C and Wi-Fi and it acts as a hub for compatible Airthings Wave monitors, extending remote access across your full multi-room system.
- Wave to check air quality
- A simple hand wave in front of the View Plus activates a green, yellow, or red LED — a color-coded air quality status at a glance.

Wherever you use your View Plus monitors, you'll get full visibility into the air quality and the power to improve the air your family breathes.
Monitor the air around you
Radon
You can't see or smell it, but long-term exposure to this radioactive gas is the top cause of lung cancer in non-smokers.
Particulate matter (PM 2.5)
Fine particulate matter (PM2.5) reaches deep in the lungs causing short-term discomfort and long-term health risks.
Carbon Dioxide (CO2)
When it reaches high levels indoors, carbon dioxide (CO2) can cause poor sleep and trouble concentrating.
Temperature
Temperature is not just a matter of comfort, it can negatively affect sleep quality, mood, and alertness.
Airborne chemicals (VOCs)
Volatile organic compounds (VOCs) are airborne chemicals emitted by everyday items - many are harmless but some are toxic.
Air pressure
Changes in air pressure affect radon levels and, for some, they can trigger headaches, joint stiffness and pain.
Humidity
High humidity promotes mold growth and aggravates asthma symptoms, while too-dry air can lead to skin and throat irritation.
Designed for the spaces you use most
Two View Plus monitors, right where life happens: The View Plus Duo is designed to monitor the areas you spend the most time in, such as the hall and living room, giving you clear insights into your everyday air quality.
Understand daily air changes: These spaces are often affected by cooking, guests, cleaning products, and outdoor air. Monitoring both rooms helps you spot patterns and understand how your home’s air changes throughout the day.
Simple setup, powerful insights: By tracking key pollutants like PM2.5, VOCs, CO₂, humidity, and radon in two high-traffic areas, you get a more complete and actionable view of your indoor environment.
