How to choose
Match the monitor to kitchen sources
Cooking gives off particles and gases, so the measures that matter are particles, VOCs and CO2. The Temtop tracks PM2.5, PM10, HCHO and TVOC and adds a 12-hour trend histogram for spotting peaks. The LifeBasis covers 11 readings and the AirKnight covers 10 readings, both including PM2.5, CO2 and TVOC. The GoveeLife tracks CO2, temperature and humidity, and the SONOFF tracks PM2.5, PM10, temperature and humidity.
Alerts, power and placement
Alerts decide whether a reading gets noticed. For power, the GoveeLife runs on AC power, the LifeBasis battery lasts up to 11-12 hours, the Temtop battery lasts 6-8 hours, and the AirKnight carries a 3000mAh battery. Keep strong sprays away from the Temtop during readings.
Read trends, not single numbers
One reading only shows one moment, while a trend shows whether a peak lines up with cooking or fades after ventilation. The Temtop logs a 12-hour trend histogram and exports 3 months of data to Excel over USB. The GoveeLife app stores up to two years of data with CSV export, and the SONOFF app holds 12 months of data with export. Compare peaks across days before judging a room.
