The air quality in Butterfield Township, Michigan is currently classified as Good. The primary pollutant measured is PM2.5, with a reported concentration of 5.3 µg/m³. PM10 data are not available for this assessment, and five valid measurements contributed to the result. The assessment is based on five valid measurements collected from local monitoring stations. The reported PM2.5 concentration of 5.3 µg/m³ falls within the range typically associated with the Good category.
These values are displayed through the OpenAQ platform, which aggregates data from multiple sources to provide a unified view of ambient air quality. No additional pollutant data were reported at this time. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes
The dataset for Butterfield Township includes five pollutant measurements drawn from a single monitoring location at Houghton Lake. The five recorded rows cover nitrogen monoxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOX), ozone (O3) and fine particulate matter (PM2.5). Four of the rows were refreshed within the last 30 days, while one row (the NO measurement) is older than a month, giving the overall collection a mixed freshness profile. Because all values come from the same site, the spatial coverage is limited to that point rather than representing the whole township.
All five pollutants show a single recorded value with no observed spread: NO is 0.0001 ppm (last updated 2026-01-24 14:00 UTC), NO2 is 0.0026 ppm (last updated 2026-02-10 23:00 UTC), NOX is 0.0025 ppm (last updated 2026-02-10 23:00 UTC), O3 is 0.034 ppm (last updated 2026-02-10 23:00 UTC) and PM2.5 is 5.3 µg/m³ (last updated 2026-02-10 23:00 UTC). The median, minimum and maximum values are identical for each pollutant, indicating that the dataset captures only a snapshot rather than a range of conditions. The most recent updates cluster on 2026‑02‑10, providing a relatively fresh picture for four pollutants, while the NO reading lags behind, highlighting an uneven temporal coverage across the dataset. Users should keep in mind that air quality can vary across different parts of Butterfield Township and over time, and the current data reflects a limited set of observations from a single location.
