0-50 = good ;)
An air quality index (AQI) level of 301 or higher is considered hazardous, indicating that the air quality poses significant health risks, especially for sensitive groups. It is crucial to take precautions when AQI levels reach this point to minimize exposure to pollutants and protect one's health.
An air quality index of 0-15 is considered good, with little to no risk to health. This level indicates that the air quality is clean and poses minimal health concerns for the general population.
A benchmark is the minimum level of quality a product must reach. Any product falling below the benchmark is considered to be of poorer quality.
The ideal parts per million (ppm) level for water quality is typically considered to be below 500 ppm. This level ensures that the water is safe for consumption and other uses.
