Use the live AQI map to see outdoor air conditions in your area. It shows one reading with a matching color for your location so you can plan time outside and focus on indoor air when needed.
The Washington AQI map shows current outdoor air for your neighborhood in one reading and color.
Traffic, wood smoke, summer ozone, regional wildfire smoke, inversions, and dust drive day-to-day changes.
Check the map before plans and recheck if wind, heat, or smoke changes.
Close windows, use recirculation, avoid indoor smoke, and use a suitable Filterbuy MERV 8, 11, or 13 filter to reduce indoor particles.
Open the map and check the reading for your town or ZIP code. Lower readings with cooler colors mean cleaner air; higher readings with warmer colors mean more pollution. If today’s map shows higher levels, keep outdoor time shorter or move harder activity indoors. This matters most for people with asthma, COPD, or heart disease, and for young children and older adults. Conditions can differ by neighborhood, so it helps to compare nearby areas.
Several common sources affect day-to-day conditions.
Traffic near major roads, ports, and ferry routes
Wood smoke on cold, still nights
Summer ozone on hot, sunny afternoons
Wildfire smoke from Washington, Oregon, Idaho, or British Columbia
Valley inversions in central/eastern areas that trap smoke and exhaust
Knowing the source makes it easier to decide when to go out and when to wait.
Treat the AQI map like a weather check. Look in the morning before errands, exercise, or school activities, and recheck if wind shifts, heat builds, or smoke appears in the forecast. People who work outdoors should glance again around midday to decide whether to move heavy tasks earlier or later.
Keep hard exercise shorter and choose routes away from heavy traffic. Take more breaks, drink water, and rest in shade or indoor areas when you can. If coughing, chest tightness, or shortness of breath starts, move activity indoors and rest.
On days with higher readings, a few simple habits help.
Keep windows and exterior doors closed during the worst hours
Run AC/HVAC on “recirculate” instead of pulling outdoor air
Avoid indoor smoke and strong fumes (no smoking indoors; skip wood fires; limit heavy sprays)
If available, run a portable air cleaner in the bedroom or main living area
These steps help at least one room stay cleaner while outdoor levels change.
When the AQI improves after a smoke event, a short cleanup helps bring indoor levels down faster. Wipe hard surfaces with a damp cloth, then vacuum carpets and rugs with a HEPA-type vacuum if you have one. Wash bedding and frequently used throws. Let your HVAC fan run for a few hours with a clean filter in place, then check the filter and replace it if it looks loaded. If you used a portable air cleaner, clean or replace its prefilter per the maker’s instructions. These small steps help clear residue that can linger after outdoor smoke moves on.
MERV shows how well a filter captures particles.
If your goal is basic dust control, pick MERV 8.
If you have a cat or dog or notice mild allergies, buy MERV 11.
If wildfire smoke or city haze bothers your home and your system allows it, use MERV 13.
Filterbuy provides U.S.-made pleated filters in many standard and custom sizes so the filter seats properly and reduces air bypass. The synthetic, pleated media captures more than basic fiberglass while supporting airflow when changed on time. Orders ship fast with free shipping in the continental U.S., and Auto-Delivery helps you stay on schedule.
A live map that shows current outdoor air conditions for your location using one reading and a matching color.
Check before outdoor plans and again if wind changes, heat builds, or smoke is in the forecast.
Not always. Ozone or fine particles can be high even when the sky looks clear.
Keep outdoor time shorter, switch hard exercise indoors, and choose routes away from heavy traffic.
Close windows during the worst hours, use AC/HVAC on recirculate, avoid indoor smoke and strong sprays, and run a portable air cleaner if you have one.
Use MERV 8 for basic dust, MERV 11 for homes with pets or mild allergies, and MERV 13 if smoke or haze is a concern and your system allows it.
Many homes change filters every 1–3 months; check sooner during long heating or cooling seasons.
Stop, go indoors, rest, and follow your care plan. Seek medical advice if symptoms persist or worsen.
