Bura One · air-quality monitor

Know what
you breathe.

Bura One measures fine dust, CO₂ and volatile compounds and turns them into one colour you can read from across the room. No app required. The app is there when you want it.

Inside

Three sensors.
One quiet ring.

A laser particle counter, a true CO₂ sensor and a VOC sensor sit under the cap. Air moves through the fabric band on its own, so there is no fan and nothing to hear.

At a glance

Colour you can
read from the sofa.

Green means open a book. Amber means open a window. Red means open both. The ring dims with the room at night and never blinks.

One touch

Tap for the number.
Hold for history.

A single capacitive button on top. Tap and the ring shows the current CO₂ level as a segment. Hold and it plays back the last twelve hours.

Two finishes

Graphite or sand.
Both disappear into the room.

Soft-touch shell, woven band, nothing glossy. Pick the one that matches the shelf it will live on.

Selected finish: Graphite.

Features

Built to be forgotten.
Until it matters.

This fictional product concept uses a light ring to present example air-quality readings.

01

Laser particle counter

PM1, PM2.5 and PM10 with a self-cleaning cycle every night, so readings stay honest for years.

02

True CO₂, not estimated

A dual-channel NDIR sensor measures CO₂ directly, instead of guessing it from other gases.

03

Fan-free airflow

Warm electronics pull air up through the band by convection. Silent by design, not by setting.

04

Ring, not screen

One 360° light ring. Readable from the door, invisible at night, no numbers unless you ask.

05

Local first

Twelve months of history live on the device. The app talks to it over your Wi-Fi, not our servers.

06

Works with your home

Matter-ready. Open a vent, start a purifier or switch a light when the ring turns amber.

In the box

Bura One, braided USB-C cable (1.5 m), wall adapter, a card with three sentences on where to put it.

Where to put it

Breathing height, away from the window, not on top of the fridge. The card says the same thing.
