Air,made visible.
Stand in a darkened room and light a single beam — you’ll see motes drifting through the air. Those motes are PM2.5, PM10, O₃, NO₂. Mote borrows nature’s way to show you what you breathe.
✦ A small manifesto
When you stand in a room without light, light a single beam.Because of the Tyndall effect, you’ll see motes drifting through the air — the same particles your lungs filter every minute of every day. Mote does for the eye what nature has always done for the curious.
