What Anti-Pollution Filter Should I Wear When?

The simplest method to select the proper anti-pollution filter to meet your hazard level would be to use the AQI reading or the PM 2.5 reading where you live.

There is not much benefit of the government posting these readings if we do not react to them by wearing some form of protection. Even though we should, many of us just can’t stay home.

Below are the PM2.5 concentration levels and the AQI Range as a reference:

The above calculator is based on the work from the US EPA Air Now calculator, available at

AQI Colors

EPA has assigned a specific color to each AQI category to make it easier for people to understand quickly whether air pollution is reaching unhealthy levels in their communities. For example, the color orange means that conditions are “unhealthy for sensitive groups,” while red means that conditions may be “unhealthy for everyone,” and so on:

Each category corresponds to a different level of health concern. The six levels of health concern and what they mean are:

  • “Good” AQI is 0 to 50. Air quality is considered satisfactory, and air pollution poses little or no risk.
  • “Moderate” AQI is 51 to 100. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.
  • “Unhealthy for Sensitive Groups” AQI is 101 to 150. Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
  • “Unhealthy” AQI is 151 to 200. Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.
  • “Very Unhealthy” AQI is 201 to 300. This would trigger a health alert signifying that everyone may experience more serious health effects.
  • “Hazardous” AQI greater than 300. This would trigger a health warnings of emergency conditions. The entire population is more likely to be affected.
