AQI Color Chart: What Green to Maroon Means | Filterbuy

Welcome to the audio version of the following web page: https://filterbuy.com/resources/air-quality/aqi-color-chart/  In this episode, we explain how to read an Air Quality Index color chart and understand what each category means for your health. You’ll learn how the scale progresses from green for good air quality to maroon for hazardous conditions. We also discuss how rising AQI levels can affect children, older adults, and people with asthma, allergies, or other respiratory sensitivities. Recognizing the colours and health categories can help you decide when to limit outdoor activity or take additional precautions. Beyond understanding the AQI scale in the United States and Canada, indoor air testing, winter HVAC care, heat-pump operation, and the distinction between vent and furnace filters can help homeowners manage indoor conditions more effectively. Selecting the correct filter size and MERV rating, replacing filters regularly, and choosing suitable options from Amazon, Walmart, Target, and The Home Depot can help reduce allergens, dust, and other airborne particles.
