App feature: How to use the air quality index feature

Did you know that poor air quality is considered the greatest environmental risk to health in the UK?

Pollutants such as ground-level ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulphur dioxide, and others can trigger various health problems such as lung irritation and inflammation, asthma attacks, and reduced pulmonary function.

While steps are being taken to reduce the amount of toxic particles in the air, it is a good idea to be mindful of what levels in your area are. So, we have the Air Quality Index feature in our app.

The AQI is measured from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.

The AQI is divided into six categories:

Each category corresponds to a different level of health concern. For example, if the AQI is less than 51, no health impacts are expected, and the air quality is considered good. An AQI between 51 and 100 is satisfactory for most individuals, but could affect certain sensitive groups.

When AQI values are at or above 101, the air outside is possibly unhealthy and could adversely impact sensitive groups.

Anything over 200 is considered harmful for most individuals, and everyone should limit outdoor exposure. The highest category of AQI is hazardous to almost all individuals, and it's recommended to stay indoors until conditions improve.
