Terrestream vs Awair Element

Last reviewed June 10, 2026. Awair support describes Element as measuring temperature, relative humidity, CO₂, total VOCs, and PM_2.5, with an Awair Score in the app.

Where Awair fits. Awair Element is a straightforward home monitor for the core comfort and indoor-air channels. It is easy to explain and may be enough when you only need the classic five-factor set.

Where Terrestream differs. Terrestream adds PM₁, PM₄, PM₁₀, NO_x index, pressure, and light, then uses the dashboard to explain patterns with outdoor context and history.

Factual distinction. Awair Element is the compact score-driven comparison point. Terrestream has more channels and an interpretation layer around source patterns.
