10 Best Home Air Quality Monitors 2025 in the United States

The Amazon Smart Air Quality Monitor is designed to help you understand and keep track of indoor air quality. It measures five key factors: particulate matter (PM 2.5), volatile organic compounds (VOCs), carbon monoxide (CO), humidity, and temperature. The device offers a color-coded LED indicator for quick air quality status checks and provides detailed information through the Alexa app. Notifications and routines can be set up for proactive air quality management, including controlling other Alexa-enabled devices like air purifiers and fans. This integration makes it particularly useful for those already using Amazon's ecosystem.

The monitor is designed for ease of use, making it suitable even for non-tech-savvy individuals. It is compact and portable, weighing just 120 grams and featuring a small footprint. The accuracy of the measurements is reasonably good, but the device does have some limitations. For example, the temperature and humidity range is not suited for extreme conditions, and the accuracy diminishes at the limits of its measurement ranges. Additionally, it only supports 2.4GHz Wi-Fi, which may be a drawback for some users.

The power source is a standard 5V micro-USB, which should be easy to manage, but the reliance on a constant power supply rather than a battery could limit where it can be placed. If you have a smart home setup with Alexa, this device fits well within that ecosystem, providing useful integrations and automations. If you are looking for a standalone device with broader compatibility and offline capabilities, you might need to explore other options.

The Airthings 2960 View Plus is a comprehensive home air quality monitor that excels in detecting a wide range of pollutants including radon, PM2.5, CO2, VOCs, humidity, temperature, and air pressure. This extensive detection capability makes it a strong candidate for anyone looking to monitor multiple aspects of indoor air quality, particularly those concerned about radon exposure. The device uses electrochemical sensors known for their accuracy, enhancing its reliability in providing precise readings.

The data is accessible via the Airthings app, which offers live data tracking and trend analysis, making it easy for users to stay informed about their air quality and receive timely notifications and tips for improvement. The app's interface is user-friendly, but the dependency on internet access for full functionality might be a drawback for some users. Connectivity options are robust, with compatibility with Alexa and other smart home devices, adding a layer of convenience for tech-savvy users. The monitor is battery-powered, offering cable-free placement, and boasts an impressive battery life of up to 2 years, which reduces maintenance hassles.

The device is compact and portable, with a sleek and understated design, making it easy to place discreetly in any room. It comes with a five-year warranty upon registration, providing added peace of mind. The Airthings 2960 View Plus is a well-rounded and highly functional air quality monitor, ideal for those looking to track a wide range of pollutants with ease and reliability.

The Airthings 2989 View Radon is a radon monitor that also tracks humidity and temperature, making it versatile for home air quality monitoring. Its radon sensor technology is touted as accurate and robust, providing reliable data to help protect your family from radon exposure. The customizable display allows users to set preferences on what data to show, and a simple hand wave can trigger sensor readings, which are color-coded for ease of understanding.

More detailed readings can be accessed through the Airthings mobile app or online dashboard, which includes graphs, notifications, and insights. This device is wireless and WiFi-ready, allowing for flexible connectivity options. The monitor is powered by 6 AA batteries, offering up to three years of battery life, which is impressive for a device with continuous monitoring capabilities.

The compact size and light weight make it portable and easy to place around the home. However, it only detects radon, humidity, and temperature, so users needing a broader range of pollutant detection might find it lacking. Additionally, while the app and online dashboard add value, those not comfortable with technology might find it slightly complex to navigate. Perfect for users primarily concerned with radon exposure and looking for a device with a long battery life and easy setup.
