10 Best Air Quality Meters 2025 in the United States

The Airthings 2960 View Plus is a comprehensive air quality monitor that measures a wide range of pollutants, including radon, PM2.5, CO2, VOCs, humidity, temperature, and air pressure. The device is WiFi-connected and requires the Airthings app for full functionality, allowing users to access live data and receive notifications about air quality.

Its always-on sensors provide continuous monitoring, which is beneficial for those wanting to keep a close eye on their indoor air environment. The device promises high accuracy in detecting radon, a significant concern as it is a leading cause of lung cancer among non-smokers.

The monitor is battery-powered (with an average battery life of two years) and offers a cable-free setup, enhancing its portability and ease of placement in various locations. It features a customizable eInk display and is compatible with devices like Alexa and the Airthings Hub, which adds to its versatility.

The Amazon Smart Air Quality Monitor is a helpful device for those wanting to keep track of indoor air quality. It measures five key pollutants: particulate matter (PM 2.5), volatile organic compounds (VOCs), carbon monoxide (CO), as well as monitoring humidity and temperature. This variety helps ensure a comprehensive overview of your air quality. The device is relatively accurate, although it has a margin of error that varies depending on the pollutant being measured. For example, temperature and humidity measurements are quite precise, but CO and PM 2.5 have higher error margins.

The color-coded LED provides a quick visual indication of air quality, and more detailed information can be found in the Alexa app, which is user-friendly and easy to navigate. The device can also send notifications and even trigger Alexa routines to activate other smart home devices if the air quality drops, adding an extra layer of automation and convenience. One downside is that it requires a continuous power source, as it operates via a micro-USB cable connected to a power adapter. It is also designed for indoor use only and has a limited range for temperature and humidity. On the plus side, it's compact and lightweight, making it easy to place anywhere in your home.

Compatibility with all Echo devices and the Alexa app ensures seamless integration into your existing smart home setup.

Its high-precision external sensors offer very accurate readings, picking up even small changes in air quality. The device responds quickly and features a large, bright 7-inch LED display that makes it easy to see all measurements at a glance without navigating through menus. There are seven different alert buzzers to notify you instantly if air quality drops, which helps maintain a safe environment, and the mute button allows you to silence alarms when needed. Switching between Fahrenheit and Celsius or 12/24 hour time formats is straightforward. Portability is a plus as it runs on a rechargeable 2500mAh battery for up to 8 hours without being plugged in, and it includes a USB-C charger. It is compact and lightweight enough to move around your home easily.
