Unearthing Air started as a research project to make the invisible, visible. Not just visible, but decipherable and actionable.
Air pollution carries invisible impacts but using the right tools and know-how can make a fresher indoor environment attainable. In a lot of ways, breaking down air and rebuilding from scratch is a solid approach to understanding the ways you impact air and the ways it impacts you.
This website is a text-based data visualization of indoor air quality from a single day in October 2024.
PM2.5—fine particulate matter smaller than 2.5 micrometers—ghostwrites our indoor life. Outdoor particles come from a variety of sources, but indoor PM2.5 emerges from the quiet rituals that turn a house into a home. These microscopic particles can slip past your body’s defenses, causing health and well-being issues.
This website makes the invisible narratives in air visible–through the text itself. Each particulate in the visualization emerged from everyday indoor activities like cooking, smoking, cleaning, heating, and spraying. As particle levels rise, the text pollutes into illegibility. More pollution, more distortion.
The text you see reflects the PM2.5 level at the time you visit. Use the timeline fixed at the bottom to scrub through the air quality changes throughout the day.
Hovering over a polluted letter reveals its origin and its linger life. As time passes and particles disappear from the air, the letters recover their original legibility.
PM2.5 is measured in micrograms per cubic meter (µg/m³), a representation of how many particulates are floating in your air. Here’s a translation of what those numbers mean over a 24-hour average, in the familiar language of the Air Quality Index (AQI):
