Indoor air carries CO₂ from breathing, particulates from cooking and cleaning, volatile organic compounds from furniture and finishes, and nitrogen oxides from gas appliances. None of these are visible. Most are odorless. All affect how you sleep, think, and feel. Lumair makes the invisible visible.
How Lumair works.
Sense
Six precision sensors capture CO₂, particulates, VOCs, NOx, temperature, and humidity every second.
Show
The 2.8-inch touchscreen displays your air quality at a glance. No phone required.
Sync
Readings push to your private dashboard every minute. Track trends, set alerts, see history from anywhere.
On the device
Five pages of clarity. No setup, no apps to open.
Swipe through real-time readings on a bright 2.8-inch touchscreen. Air quality status in plain English. Threshold-based color coding. Touch settings to adjust brightness, switch units, or check device info. Lumair works the moment you plug it in.
On the platform
The full picture, from anywhere.
Your Lumair dashboard tracks every reading, every minute, going back as far as you've owned the device. Watch trends across hours, days, or weeks. Switch between multiple devices in your home or office. See exactly when air quality slipped, what triggered it, and what to do about it.
- Real-time readings with sub-second updates
- Historical charts (1 hour / 24 hours / 7 days / custom)
- Multi-device support with quick switching
- Air Quality Score (0–100) across all metrics
- CSV export for analysis or compliance
- Mobile-responsive — works on every device
Every metric that matters indoors.
CO₂
Carbon dioxide builds up in enclosed spaces and impairs focus, sleep, and cognitive function.
Healthy: under 800 ppm
PM1.0
Ultra-fine particles from cooking, candles, and combustion that penetrate deep into your lungs.
Healthy: under 10 µg/m³
PM2.5
Fine particles linked to cardiovascular and respiratory disease. EPA's primary outdoor air metric.
Healthy: under 12 µg/m³
PM4.0
Coarse particles from dust, pollen, and mechanical activity in your living space.
Healthy: under 25 µg/m³
PM10
Larger particles you can see in sunbeams — dust, mold spores, pollen.
Healthy: under 50 µg/m³
VOC
Volatile organic compounds from furniture, paint, cleaning products, and personal care items.
Healthy: under 150 index
NOx
Nitrogen oxides from gas stoves, fireplaces, and water heaters — a respiratory irritant.
Healthy: under 20 index
Temperature
Indoor temperature affects sleep, focus, and humidity perception.
Healthy: 18–26 °C · 65–78 °F
Humidity
Too dry irritates airways; too humid promotes mold and dust mites.
Healthy: 40–60%
Use cases
Wherever air quality matters.
From homes to restaurants, schools to clinics — Lumair scales with your space.
