Air quality today
The air quality in Maidstone today is classified as Good. The primary pollutant measured is PM2.5, with a recorded concentration of 6.44 µg/m³ based on five valid observations reported through OpenAQ.
Overall conditions meet the Good category criteria, and the available data reflect the current level of fine particulate matter. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The dataset for Maidstone contains measurements from six individual sensor rows, each reporting a single set of values for the pollutants that are currently available: PM1, PM10, PM2.5, relative humidity, temperature and UM003 (particle count). All of these readings come from the West Farleigh monitoring site, so the spatial coverage is limited to one location within the wider city area.
The most recent data were recorded on 2026‑02‑10 at 21:00 UTC for five of the six parameters – PM1, PM2.5, relative humidity, temperature and UM003 – indicating that those values are up‑to‑date within the last week. The PM10 measurement is older, with its latest timestamp on 2025‑01‑13 at 23:00 UTC, which means it reflects conditions from more than a year ago. Because each pollutant has only one recorded value (the minimum, median and maximum are identical), there is no observed spread or variability in the data; for example, PM1 registers exactly 3.3423333485921223 µg/m³ and UM003 records precisely 720.2916666666666 particles/cm³.
Given that all six rows originate from a single station, the dataset does not capture spatial differences across Maidstone and relies heavily on one point in time for most variables. The freshness of five parameters is good, but the outdated PM10 reading highlights an uneven temporal coverage across pollutants. Users should keep in mind that conditions can change throughout the city and over time, and the current figures represent a snapshot rather than a comprehensive picture of air quality throughout Maidstone.
