Does Air Quality Change By Cleveland Neighborhood?

Yes, and by more than a city-wide number admits. Three things drive it: proximity to the Cuyahoga industrial valley, proximity to I-90, I-71, I-77 or I-480, and wind direction. Prevailing winds run west to east, so west-side communities generally sit upwind of the valley and east-side ones downwind.

The monitor network follows that geography. Brookpark reads the west side. Harvard Yards sits in Newburgh Heights, inside the industrial corridor. Cleveland Near Road measures what people breathe beside a highway, a different question from the city average. Mayfield, at the eastern edge, catches ozone once the wind has carried it across town.

What Is Cleveland's Air Quality Forecast For The Next Three Days?

Forecasts come from Northeast Ohio Areawide Coordinating Agency (NOACA), which forecasts ozone and fine particles daily across eight counties: Ashtabula, Cuyahoga, Geauga, Lake, Lorain, Medina, Portage and Summit.

A forecast earns its keep the day before. The Akron air quality index often moves first when pollution comes from the south.

Is There An Air Quality Alert In Cleveland Today?

Check the map above for current status. NOACA issues an advisory when ozone or fine particles are forecast to reach unhealthy levels for sensitive groups, and the National Weather Service has relayed them since May 1, 2019, which is why they surface as Air Quality Alerts in weather apps.

On an advisory day NOACA asks residents to drive less, avoid idling, refuel after sunset and hold off mowing. The EPA adds the indoor half: windows closed, HVAC running. You can sign up for NOACA's free advisory emails. The Cleveland Division of Air Quality also keeps a recorded line at (216) 664-7442, updated weekdays, which almost nobody knows about.

What Are PM2.5 Levels In Cleveland Today?

For current PM2.5 levels, refer to the map above. PM2.5 is soot and smoke fine enough to reach the bloodstream. It is what makes the sky hazy during smoke events, and what a high-MERV filter is built to capture.

The particle problem, unlike ozone, has not improved. The “State of the Air 2026” report puts the Cleveland-Akron-Canton metro 12th worst nationally for year-round particle pollution and 39th for short-term spikes.

For scale, the EPA's annual standard is 9 micrograms per cubic meter, the 24-hour standard 35. One hour above either is not a violation, because the standards are averaged, but it describes what you are breathing now.

What Are Ozone Levels In Cleveland Today?

Refer to the map above to see whether ozone is driving Cleveland's air quality. Ozone is not emitted directly. It forms when nitrogen oxides and volatile organic compounds react in sunlight and heat, which is why smog climbs on hot afternoons and falls overnight.

Cleveland's ozone status changed this summer and most air quality sites have not caught up. On June 29 the EPA redesignated the Cleveland area to attainment for the 2015 eight-hour standard, ending eight years of nonattainment that had escalated to a Serious classification. The margin was nothing: a 2023 to 2025 design value of exactly 0.070 ppm against a 0.070 ppm limit. Ohio's maintenance plan runs to 2038.

Two caveats. The clean data determination relied on excluding several June 2023 readings driven above the standard by Canadian wildfire smoke, which the EPA concurred were exceptional events. And attainment for ozone says nothing about soot: Cuyahoga County still fails on particle pollution.

Here is the part most air quality pages skip, and Filterbuy makes the filters, so take it as said against interest. Ozone is a gas and filters trap particles. MERV 8, 11 and 13 do very little for it, and neither does a HEPA purifier. On an ozone day the honest advice is windows closed, system recirculating, no hard outdoor workout.

What Is The Pollen Count In Cleveland Today?

Pollen sits outside the Air Quality Index, so the map above will not show it. The AQI tracks regulated pollutants only, which is why a green day can still be miserable if you have allergies. Check a pollen forecast alongside the map, not instead of it.

Pollen grains are large as airborne particles go, so MERV 11 air filters capture them effectively.

Is Wildfire Smoke Affecting Cleveland Right Now?

Check the map above to see whether fine particles are elevated, and watch plumes move on our live wildfire and smoke map.

While smoke sits over the city, three moves cut exposure:

1. Close windows and doors, shut off anything drawing outside air in, and recirculate.

2. Run MERV 13 if your system takes it, which the EPA recommends during smoky periods, and a HEPA purifier in each room you are using.

3. Check the filter weekly. Smoke loads it fast, and a clogged filter stops working and strains the blower.

No MERV 13 or purifier in the house tonight? Do not order and wait. The EPA has tested box-fan-and-filter cleaners and found them a cheap substitute; its DIY air cleaner research has the build. Filterbuy sells filters, and would rather you built one tonight than breathe smoke waiting on delivery.

One caveat from our reviewer, David Clark: if the system develops weak airflow, icing or noise after an upgrade, step down a MERV rating and call a technician.

Which Filter Matches Cleveland's AQI Today?

Read your band from the map above. Above an AQI of 100 the EPA-recommended setup is a MERV 13 filter in your HVAC system plus a HEPA purifier in each room you use. With no central system, the purifiers do the whole job.
