Airthings View Plus

The Airthings View Plus stands out as the most comprehensive indoor air quality monitor available, tracking seven critical air quality components including radon gas, particulate matter (PM2.5), carbon dioxide (CO2), volatile organic compounds (VOCs), humidity, temperature, and air pressure. Its ability to detect radon - a radioactive gas linked to lung cancer - makes it unique among consumer-grade monitors. The device features a simple, rounded design with an e-ink display that shows two metrics at a time, though users can cycle through all measurements by waving their hand over the sensor. Battery life is exceptional, lasting up to two years on six AA batteries, though it can also be powered via USB. The accompanying smartphone app provides color-coded indicators for each pollutant and tracks 30 days of historical data. While the View Plus is more expensive than many competitors, its comprehensive sensor array and reliable performance justify the investment for those serious about indoor air quality. The device integrates with smart home platforms like Alexa and Google Assistant, allowing for automated responses to air quality changes. Some users may find the display limited compared to full-screen competitors, and the USB port's placement under the battery compartment is inconvenient for permanent wired installation.
