Use cases
Business travel to high-PM cities, checking whether to open hotel windows, and validating indoor air during wildfire season on the road.
Accuracy trade-offs vs stationary monitors
Portable sensors trade some accuracy and sensor lifespan for size and battery life — most use smaller laser-scattering modules than desktop units, which can be more sensitive to how you're holding or wearing them (airflow across the intake affects the reading).
Treat a portable monitor's number as a same-city, same-day comparison tool (this room vs that room, this street vs that street) rather than an absolute reference. For an area's official outdoor baseline, cross-check against the live AQI for your destination city on Aether before you travel.
