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.
What it protects against
All protection guides
 Mould & damp risk Invisible until it is not. Allergies & dust sensitivity The 40–50% RH sweet spot. Long-term toxic gas exposure What you cannot smell, Envora can. Cooking pollution Your kitchen is an industrial chimney. Sleep & bedroom air Sleep is an environmental sport. Winter dry air Heated air is parched air. Outdoor air events When the air outside is worse than inside.

Sensors

Eleven channels. One truth.

Each channel measured by the best tech available in its class. NDIR for CO₂. Electrochemical for low-level CO. Laser scattering for particulates. Bosch BME690 for climate and VOCs — all fused into a single IAQ score.

Calibration

Every unit. Certified before it ships.

We reference-test every Envora against a laboratory-grade panel before it leaves our bench. The signed certificate ships in the box and is available by serial number at any time.

  • CO₂ reference
    NDIR · 4-point at 0, 500, 1500, 5000 ppm
  • CO reference
    4-point electrochemical vs EPA trace gas
  • PM reference
    Gravimetric, 3-sample average
  • T / RH reference
    ISO 17025 chamber to 0.1 °C / 1 %RH
