Overview of the eleven measurements
Carbon Dioxide ppm The breath signal. How fresh is the air you are in? Carbon Monoxide ppm Low-level exposure, tracked over time. Particulate Matter µg/m³ See what you breathe. Down to one micrometre. Temperature & Humidity °C · %RH Comfort is a range, not a number. Barometric Pressure hPa Weather, altitude, storms — all in one number. VOC & IAQ Index index Every gas. Every particle. One honest score. Sound Level dBA The ambient floor, measured — never recorded. Ambient Light lx Your circadian signal, measured.
For your space
All solutions
 Home Kitchens, bedrooms, nurseries, basements. Envora shows you what you breathe — and tells you how to fix it, usually for free. Office & Co-work CO₂ is the single strongest environmental lever on office productivity — and the cheapest to fix. Envora gives facilities teams and founders the number to argue with. CO₂ and indoor air quality monitoring for schools Classroom CO₂ and indoor air quality evidence for better ventilation decisions, measurable cognitive lift, and the data trail governors and parents want. Labs & Clinics Envora One is precise enough for laboratories, clinics and regulated spaces, and comes with a signed calibration certificate per device ID. Studios & Gyms Hot yoga, spin, HIIT and small studios generate extreme humidity and CO₂ loads. Envora tells you how your ventilation is holding up — live, per-room, per-class. Podcasts & Studios Envora flags the HVAC hum, the fridge compressor, the neighbour's drill — and the concentration drift that flattens your delivery — before the tape picks any of it up. Landlords & Letting Continuous, timestamped indoor air quality records for every unit you manage — so damp disputes end in data, not arguments.

Choose Envora One if

You actually want to do something with the data — track CO₂ during sleep, log PM2.5 from cooking, set up automations in Home Assistant, export evidence for a damp dispute.

Choose the Amazon monitor if

FAQ

Comparison FAQ.

Does the Amazon Smart Air Quality Monitor measure CO₂?
No. As of the latest publicly listed specifications it does not include a CO₂ sensor — it measures PM2.5, TVOC, humidity, temperature and carbon monoxide. Envora One adds a dedicated NDIR CO₂ sensor, which is the single most important channel for ventilation decisions.

Can I get the raw numbers out of Amazon's monitor?
The Amazon device exposes a coloured indicator and summary status to Alexa users; raw numerical history and integrations with non-Alexa platforms are limited. Envora One exposes every channel via API, MQTT and CSV.

Is Envora One worth the price difference?
If you care about the data, yes. The Amazon monitor is an indicator. Envora One is an instrument — eleven channels, calibrated, with a paper trail and integrations from day one.
