# Air Quality Card

> Air Quality Card is a dashboard card for Home Assistant. It has 117 GitHub stars and was last updated October 13, 2026.

Air Quality Card is a dashboard card that shows indoor air quality readings as gradient graphs with health-based thresholds. It covers gases, particulates, humidity, temperature, pressure and noise, and the graph colors change with the air quality level and update as new readings arrive. Thresholds draw on WHO 2021, US EPA/OSHA and EU guidance where it exists. Critical warnings appear for carbon monoxide, propane and low oxygen, and a separate banner gives a long-term radon advisory. The status badge can use an air quality index entity, or the card works out the status from the configured sensors. Optional outdoor sensors add a dashed comparison line with ventilation recommendations, and the card is set up through the visual editor or YAML, installed via the Marketplace or HACS.

## From the README

> A custom Home Assistant Lovelace card for monitoring indoor air quality with beautiful gradient graphs and WHO-based health thresholds.
>
> - Real-time monitoring of CO, Radon, CO2, PM2.5, PM10, PM1, PM0.3, HCHO, tVOC, NOx, O2, NO2, O3, Propane, humidity, temperature, atmospheric pressure, and noise
> - CO, Propane, and low-O2 safety alerts -- critical red warnings for dangerous carbon monoxide, gas leak, or oxygen-deficient levels
> - Radon advisory banner -- separate long-term health advisory with EPA/WHO thresholds (supports pCi/L and Bq/m3)
> - Gradient-colored graphs that change color based on air quality levels and update live as new readings arrive
> - Interactive hover/touch to see historical values at any point
> - Health-based thresholds anchored to WHO 2021, US EPA/OSHA and EU guidance where it exists (see Health Thresholds)
> - Unit-aware — CO, NO₂, O₃ and HCHO readings in µg/m³, mg/m³, ppb or ppm are converted automatically; numbers, times and time zones follow your Home Assistant profile settings
> - Actionable recommendations like "Open Window" or "Run Air Purifier"
> - Outdoor sensor comparison - optional dashed line overlay with smart ventilation recommendations
> - Tap to expand - click any graph to open the full Home Assistant history view
> - Visual configuration editor - Home Assistant's built-in form editor, no YAML required, with collapsible sections for clean organization
