        "content": "When you see an air quality reading (AQI) of **147**, that falls into the \u201cUnhealthy\u201d category for the United States EPA scale. Here\u2019s a breakdown of what that means and how the scale works:\n\n---\n\n### \ud83c\udff7 AQI Categories & What a Rating of ~147 Means\n\n| AQI Range | Label | Who it Impacts | What to Do / Health Advice |\n|-----------|-------|----------------|-----------------------------|\n| 0\u201350 | **Good** | Everyone\u2014air pollution poses little or no risk. ([epa.gov](https://www.epa.gov/ozone-pollution-and-your-patients-health/patient-exposure-and-air-quality-index?utm_source=openai)) |\n| 51\u2013100 | **Moderate** | Acceptable for most\u2014some risk for unusually sensitive people. ([www3.epa.gov](https://www3.epa.gov/airnow/mobile/AQItable.htm?utm_source=openai)) |\n| 101\u2013150 | **Unhealthy for Sensitive Groups** | Higher risk for people with asthma, older adults, children, and those with lung or heart conditions. ([epa.gov](https://www.epa.gov/wildfire-smoke-course/communicating-air-quality-conditions-air-quality-index?utm_source=openai)) |\n| 151\u2013200 | **Unhealthy** | Everyone may begin to experience health effects. Sensitive groups more seriously so. Your 147 AQI is just below this\u2014but close. ([www3.epa.gov](https://www3.epa.gov/airnow/mobile/AQItable.htm?utm_source=openai)) |\n| 201\u2013300 | **Very Unhealthy** | Health alert\u2014everyone may experience more serious effects. ([aqs.epa.gov](https://aqs.epa.gov/aqsweb/documents/codetables/aqi_breakpoints.html?utm_source=openai)) |\n| 301\u2013500 | **Hazardous** | Emergency conditions. Serious risks for all. ([www3.epa.gov](https://www3.epa.gov/airnow/mobile/AQItable.htm?utm_source=openai)) |\n\n---\n\n### \ud83d\udd0d What a 147 AQI Implies\n\nIf your current AQI is **147**, that typically means:\n\n- It\u2019s in the **\u201cUnhealthy\u201d** range (151\u2013200). But since 147 is just below that, you\u2019re actually still in the **\u201cUnhealthy for Sensitive Groups\u201d** category (101\u2013150).  \n- Though the general public may not feel much, people in sensitive groups (children, older adults, people with chronic lung or heart disease, etc.) will be at higher risk of breathing discomfort or worse. ([www3.epa.gov](https://www3.epa.gov/airnow/mobile/AQItable.htm?utm_source=openai))  \n- Outdoor exertion should be limited for sensitive people, and everyone should take some caution. ([epa.gov](https://www.epa.gov/wildfire-smoke-course/communicating-air-quality-conditions-air-quality-index?utm_source=openai))\n\n---\n\n### \u26a0\ufe0f Practical Advice\n\nHere\u2019s what you might do given this air quality:\n\n- If you\u2019re in a sensitive group: skip or reduce physical activity outside. Wear a mask if going out. Seek cleaner indoor air if possible.  \n- If you\u2019re not in a sensitive group: you\u2019re generally okay doing what you normally do, but keep an eye on symptoms\u2014especially respiratory.  \n- Try checking what pollutant is driving the AQI (often fine particulate matter like PM\u2082.\u2085, or ozone), since that can affect what protections are best.  \n\n---\n\nLet me know your location or what pollutant is elevated (PM\u2082.\u2085, smoke, ozone, etc.) if you want tailored suggestions!"
