Air Quality Checker

Check the current air quality for a location.

How clean is the air

This checks the current air quality for a location, from live monitoring data, giving an air quality index and the main pollutants. It is useful for health-conscious planning, especially for sensitive people or on days when air quality is poor.

Understanding air quality

Air quality is usually summarised as an index that combines the levels of the main pollutants into a single easy-to-read figure and category, from good to hazardous, which tells you at a glance whether the air is healthy to breathe. This genuinely matters for health: poor air quality can affect everyone but especially sensitive groups — people with respiratory or heart conditions, the elderly, children, and those exercising outdoors, who breathe more deeply. On days when the index is poor, sensitive people may want to limit strenuous outdoor activity, and everyone benefits from awareness. Air quality varies with location, weather, traffic, industry, and events like wildfires, which can cause sharp temporary spikes. The data comes from live monitoring and needs an internet connection. It is worth noting this is general information for awareness, not medical advice; anyone with health concerns related to air quality should follow guidance from their doctor and local health authorities. Checking air quality helps you make informed decisions about outdoor activity, particularly on poor-air days or if you are sensitive.
