Temtop vs Airthings: Key Differences
Target pollutants
Temtop focuses exclusively on carbon dioxide, measuring levels from 400 to 5000 PPM. It also tracks temperature and humidity. Airthings View Plus offers a broader scope. It detects radon gas, PM2.5 particles, VOCs, CO2, humidity, temperature, and air pressure. Radon is a significant health concern, making Airthings more comprehensive for home safety. If you only need CO2 data, Temtop is sufficient. For full air quality profiling, Airthings covers more ground.
Sensor technology
Temtop uses NDIR and photoacoustic sensing for its CO2 detector. This Swiss-engineered sensor provides high precision within the critical 400–2500 ppm range. It offers 1 ppm resolution and a rapid 5-second refresh rate. Airthings relies on electrochemical sensors for its various measurements. NDIR technology is generally considered the gold standard for accurate CO2 readings over long periods. Airthings electrochemical sensors are effective for multiple gases but may differ in longevity or specificity compared to dedicated NDIR units for CO2.
Power source
Temtop is powered via a USB cable. The package includes a USB cable for connection. While it mentions a 70-day battery life in standby, it advises keeping the device plugged in for real-time monitoring. Airthings View Plus is battery-powered. This allows for cable-free placement anywhere in your home. You do not need to be near a power outlet. Battery power offers flexibility in placement, whereas Temtop requires proximity to a USB port for continuous, real-time operation.
Connectivity and alerts
Temtop provides local audio alerts. You can customize settings to disable audio and display illumination for undisturbed rest. It operates without an app or internet connection. Airthings requires the Airthings app and a Wi-Fi connection to function. It sends app notifications and saves data to the cloud. You can check live data from anywhere. Airthings also provides pollen forecasts via Breezometer. Temtop is better for offline, local monitoring. Airthings is better for remote access and trend analysis.
Form factor and size
Temtop is a portable, slim device. It measures 1.26 inches wide, 4.09 inches high, and 5.51 inches long. It weighs 4.96 ounces. It includes mounting options for versatile placement. Airthings View Plus is slightly larger and heavier. It measures 3.54 inches wide, 1.18 inches high, and 6.69 inches long. It weighs 5.76 ounces. It features a customizable e-ink screen. Temtop is more compact and portable. Airthings has a flatter profile that may sit more discreetly on a shelf or table.
