Going outside is fine for most people when the AQI is under 100 and sensitive groups should ease off above 100. The pollutant most likely driving today's

1:00number is ground-level ozone on hot afternoons or fine particle pollution, PM2.5 during wildfire smoke. Your strongest indoor protection is a MIRV-13 filter with the windows closed when the AQI climbs. Virginia's AQI updates hourly and follows the US EPA air quality index scale, which spans 0-500, 0-50 is good, green, 51-100 is moderate, yellow, 101-150 is unhealthy for sensitive groups, orange, 151-200 is unhealthy red, 2-01-300 is very unhealthy purple, and 301 and above is hazardous, maroon. On most days across the Commonwealth, the reading sits in the good to moderate range. It spikes higher during summer ozone episodes and when wildfire smoke reaches the mid-Atlantic. In our experience, helping Virginia households the figure people underestimate most isn't the daily high. It's how fast the number climbs once smoke arrives. If you're in a sensitive group,

Guidance based on USEPA and CDC recommendations. How Virginia's air quality works and what drives it? Virginia's air tells two different stories depending on the season. In summer, heat, and sunlight cook vehicle and power plant emissions into ground level ozone, which is why small galerts cluster in the warm months across northern Virginia, Richmond, and Hampton roads. Ozone irritates the lungs the way a sunburn irritates skin, and it climbs fast as on hot, stagnant afternoons. The second story is particle pollution. PM 2.5 particles are small enough to slip past your body's defenses and reach deep into your lungs. They come from traffic, industry, wood smoke, and increasingly from wildfires far outside the state. That's the shift worth understanding.

5:21Virginia used to sit downwind a very little smoke. Now the Commonwealth catches plumes from Canadian and Western fires, and those events can turn a good air morning into an unhealthy afternoon within hours. We noticed that change in our own inbox before the forecast caught up, as questions from Virginia customers about smoke-rated filters climbed within days of the haze arriving. Season, main pollutant. What drives it? Summer, ground level ozone, heat, and sunlight react with vehicle and power plant emissions. Late spring to summer wildfire smoke, PM 2.5 smoke drifting in from Canadian and Western wildfires. Winter, fine particles, PM 2.5 wood smoke, home heating, and stagnant cold air. Year round traffic and industry, PM 2.5 vehicles and local industrial sources in your metro areas. Patterns vary by year and location. Always check the live AQI for current conditions. Virginia's air also depends on where you stand.

6:23The mix that fuels a bad air day in a northern Virginia commuter suburb looks nothing like the haze that settles into a Shenandoah valley, and knowing your region tells you which pollutant to watch first. This is the part generic AQI maps leave out, so we mapped it to the Commonwealth. Region, main air quality driver, what to watch for. Northern Virginia, summer, ozone, and traffic. PM 2.5, hot, stagnant afternoons along the I-95 and I-66 corridors. Richmond Metro Summer Ozone with PM 2.5 spikes, ozone that climbs on warm days and smoke that drifts in. Hampton roads, ozone and coastal port pollution. See breeze days that trap ozone near the water. Shenandoah and Blue Ridge, regional haze and transported smoke. Hays that pools and valleys and lingers on still days. Southwest Virginia, generally cleaner air, winter wood smoke, and smoke transported from distant fires. Regional patterns are general and shift with weather and wildfire seasons. Always check the live map for your exact location. A lot of

7:28Virginians assume their home is automatically a refuge. It isn't. When outdoor PM 2.5 spikes, those particles work their way indoors through gaps, doors, and fresh air intakes. The good news is that you have real control over the air you breathe most of the day. Running your HVAC system with a high efficiency filter. Keeping windows closed during smoke events and watching the live AQI are three moves that genuinely change your exposure. Most guides skip this part. In the Virginia Homes filter by ships too, the ones that ride out a smoke event comfortably aren't the ones that react fastest. They're the ones that already had murved 13 filters rated for smoke and fine particles installed before the alert. Since that rating captures a large share of the particle sizes that make Virginia's worst air days dangerous. From the author, Michelle Wann.

15:00Question. How do I check today's live air quality index in Virginia? Answer. Use the live map at the top of this page, then enter your zip code or city for a reading specific to your area. The map pulls hourly data, so refresh it before you make outdoor plans rather than relying on an earlier forecast. Question. What AQI level is considered unhealthy in Virginia? Answer. An AQI above 100 orange is unhealthy for sensitive groups and above 150 red is unhealthy for everyone. If you have asthma, heart disease, or you're caring for young children or older adults, start limiting outdoor time once the reading hits orange. Question. Why does Virginia's air quality get worse? In summer, answer. Heat and strong sunlight react with vehicle and power plant emissions to form ground level ozone, which peaks on hot, stagnant afternoons. That's why small alerts in northern Virginia, Richmond, and Hampton roads cluster in the summer months. Question. Does

16:04wildfire smoke really reach Virginia? Answer. Yes, and we've watched it happen. Smoke from Canadian and Western wildfires now travels into the mid-Atlantic, and the June 2023 event drove parts of the region into red and purple AQI conditions. Wildfire smoke is a growing driver of Virginia's worst air days. Question. Should I run my HVAC fan on or auto during a Virginia smoke day? Answer. Set the fan to the on setting so your system filters air continuously instead of only when it's heating or cooling. Switch to recirculate or close the fresh air intake so you're not pulling smoke inside and keep the highest murvy filter your system handles. On the auto setting with a low grade filter, a smoke day mostly passes your air by. Question. Can a MIRV-13 filter overwork? An older Virginia HVAC system answer. Most modern systems handle MIRV-13 without trouble. A very old or undersized system can lose some airflow though. If your airflow feels weak or your manual caps the

17:08rating, step down to MIRV-11 or check with a technician before upgrading. Clean air shouldn't come at the cost of your system. Question. Is it safe to exercise outside in Virginia? When the AQI is moderate answer. Moderate air 51 to 100 is fine for most people. If you have asthma or you're planning a hard workout, ease up near the yellow to orange line, especially on hot summer afternoons when ozone tends to peak between about 2 and 8 p.m. Question. How long does wildfire smoke linger indoors? After Virginia's air clears, answer. Fine particles can hang in your home for hours after the outdoor number drops. Keep your fan and filter running a while longer. Hold off on candles or heavy cooking that add indoor particles and swap the filter once conditions clear if it looks loaded. Question. What air filter should I use during a Virginia air quality alert answer? For fine particles in smoke, a MIRV-13 filter is the practical choice for most homes and it's the rating the

18:13EPA points to for reducing indoor smoke particles. In our experience, the filter most homes already have installed is a step or two behind what a smoke day calls for.
