The color scheme on the Purple Air website – which corresponds to the EPA’s ‘air quality index’ or AQI – is only valid for 24-hour data. LRAPA is a conversion equation developed by Lane Regional Air Pollution Agency in Eugene, Oregon, and is best suited for our area. Calibration, also called conversion, adjusts the raw Purple Air values so that they match regulatory air monitors more closely. Then, in the same box, click the Conversion dropdown and select LRAPA.This will show values for fine particles less than 2.5 microns in micrograms per cubic meter. On the Purple Air website, in the bottom left corner, click on the Map Data Layer box and select Raw PM2.5 in ug/m 3.Go to select View Map, and zoom in on your location.To improve the accuracy of your Purple Air sensor, follow these instructions: The data need to be in the right scale and time average.There are two important considerations when looking at Purple Air data to ensure the data is accurate: We know this from placing Purple Air sensors at our regulatory monitors and comparing measurements. Raw Purple Air data are about two times higher than the real values. Many people use Purple Air sensors to learn about fine particle pollution in their area. One of the most popular air sensors is Purple Air.

To download your Purple Air data or create a report with sensor data try the Air Sensor Dashboard (beta). Just returned your sensors? Email us with feedback on the process and tell us what you learned! The data from these sensors are not owned by PSCAA and we are not responsible for their use or misuse. This means that they cannot be used for permitting, compliance, policy, or interpretation of health effects. Note: Air sensors are intended to be educational and are non-regulatory. Project approval is also dependent on the availability of agency staff and resources. The applications are scored based on priority agency locations ( see our focus community work), project scope, relevance of air sensors to answer your question, and including education and outreach. We review these applications quarterly, and will get back to you on status of your application after our next review. Please fill out the form to apply for a sensor loan. Have an air quality question that would benefit from an air sensor? Are you an educator who wants to teach kids about air quality? We now have a limited number of air sensors to loan to community groups, educators, and individuals.

The monitors that report to our website are built and operated according to rigorous air monitoring regulations determined by the Environmental Protection Agency ( EPA), and they provide high-quality data.īut air sensors can be very useful and may help answer questions about air quality, such as: These sensors are available to anyone and typically cost between $100 and $2,500 – a fraction of the cost of our regulatory air monitors.Īir sensors can estimate a variety of pollutants including: dust, fine particulate matter, carbon dioxide, carbon monoxide, ozone, nitrogen oxide, and many others.Īlthough air sensors are less expensive than a regulatory air monitor, they are also less accurate.
