True CO₂ (photoacoustic NDIR): no false spikes from perfume or cooking
VOC index, temperature, humidity and atmospheric pressure
4.2" E-Ink display and LED indication, gentle at night
Night report: a summary of your bedroom air each morning

Stop guessing why you wake up tired or lose focus during the day

Stuffy air is easy to miss. High CO₂ in a closed bedroom or office is linked to poorer sleep and lower concentration. Altruist Insight shows you when it's time to open a window.

Meet Altruist Insight, the CO₂ monitor

Precise and stable indoor CO₂ monitoring without false spikes caused by perfumes, cooking smells, candles or other everyday VOC sources.

Wake up to a report on your bedroom air

Each morning the E-Ink screen shows a Night Report: how CO₂, temperature and humidity held up while you slept, summed up in one Comfort Score. Choose a general profile or a stricter biohacking one. Pair it with Altruist Urban to add fine dust and noise to the report. The score rates your room — the part you can actually change. The E-Ink screen gives off no light, so your bedroom stays dark and calm.

Your data, your hardware, your choice

Read your data in three apps, or build your own open-source solution. With open protocols and open-source software, the sensor isn't locked to a single platform, cloud or vendor.
