How Is the Air Quality Index (AQI) Calculated? | Filterbuy

Welcome to the audio version of the following web page: https://filterbuy.com/resources/air-quality/aqi-education/how-is-the-air-quality-index-calculated/  In this episode, we explain how the Air Quality Index (AQI) is calculated and what those numbers mean for your daily health and safety. You'll learn how pollutants such as fine particulate matter (PM2.5), ground-level ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide are measured, how they contribute to AQI values, and why the highest pollutant concentration determines the overall AQI for a given location. You'll also learn how AQI categories and colour codes help communicate the severity of air pollution, who is most vulnerable during periods of unhealthy air, and why monitoring AQI is an important part of planning outdoor activities. Listeners will gain practical tips for interpreting AQI readings, recognizing when air quality may pose health risks, and improving indoor air quality through effective air filtration and proper HVAC maintenance. As you become more familiar with how AQI is calculated, it's also helpful to understand what a moderate AQI really means and when changing air quality conditions may require extra precautions. You'll also discover practical resources for choosing and maintaining MERV-rated HVAC air filters, recognizing when it's time to replace your filter, and finding Filterbuy filters through Amazon, Walmart, Target, and The Home Depot, helping you maintain cleaner, healthier indoor air as outdoor pollution levels change.
