Airthings View Plus | 7-Sensor Radon & Air Quality Monitor

Know What's in Your Air. Protect the People You Love.

Most air quality threats are invisible. You can't see radon, smell carbon dioxide, or feel particulate matter building up in your lungs — but they're there, and they're affecting your health every day. The Airthings View Plus gives you a real-time window into the air inside your home, with 7 professional-grade sensors, a free app, and clear, actionable guidance on what to do about it.

Trusted by over 1,000,000 users worldwide and backed by 15 years of air quality expertise, the View Plus is the most comprehensive home air monitor Airthings makes — and the most comprehensive one you'll find at this price point.

7 Sensors. One Device. Total Air Awareness.

• Radon — The #1 cause of lung cancer in non-smokers. Invisible, odorless, and present in millions of homes. The only way to know is to test.
• Particulate Matter (PM2.5) — Fine particles from pollution, wildfire smoke, and cooking that penetrate deep into the lungs. Laser-based detection, calibrated with a GRIMM reference instrument.
• Carbon Dioxide (CO2) — Elevated indoor CO2 from poor ventilation causes poor sleep, brain fog, and reduced concentration — even at levels you'd never notice.
• Airborne Chemicals (VOCs) — Gases emitted by cleaning products, furniture, paints, and kitchen activity. Metal-oxide sensor, self-calibrating using the cleanest air it's exposed to.
• Humidity — Too high promotes mold and dust mites. Too low irritates skin and airways. The sweet spot is 30–60%. Accuracy: within 3%.
• Temperature — Impacts sleep quality, alertness, and comfort. Optimal sleep: 60–65°F. Optimal focus: 68–72°F. Accuracy: within 1°F.
• Air Pressure — Pressure changes affect radon levels and can trigger headaches and joint pain in sensitive individuals. Accuracy: within 0.6 mBar/hPa.

Why Radon Demands Your Attention

Radon is a naturally occurring radioactive gas that seeps into homes through cracks, floors, and foundations — completely undetectable without a sensor. According to the U.S. EPA, radon is the second leading cause of lung cancer — responsible for over 21,000 deaths per year. Living in a high-radon home can be equivalent to smoking 10 cigarettes a day without knowing it.

Every home is different. Even neighboring houses can have vastly different radon levels. The only way to know is to measure.
