• DESIGNED FOR HOME, OFFICE & BEDROOM: This compact co2 monitor fits any space — desk, nightstand, or wall-mounted. A 1500mAh backup battery keeps it running when unplugged, with low-battery warnings so you're always in the know. Track rising CO₂ to know when fresh air is needed. Ideal for families, remote workers, and anyone who cares about better sleep and sharper focus — with a smart air quality monitor you can trust.
