Where the two actually differ on the specs we track (3 of 7). Matching specs are omitted.
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Only two whitelisted outlets mention this exact model, and neither lab-measured it. Digital Trends' 2023 roundup praises the M10's large, easy-to-read display, portability and built-in alarm while flagging its roughly 6-hour battery. Wirecutter's Oct 2025 guide references the M10 only in its competition section as a 'former pick,' having moved on to the AirGradient One. No measured benchmarks exist. (2 sourced reviews.)
Praised: Large, easy-to-read display; Portable, grab-and-go design; Built-in alarm for pollutant spikes.
Flagged: Short battery life, about 6 hours per charge; No longer a Wirecutter pick, relegated to a 'former pick'.
