AQI is slow to drop after spike #15

If my PM2.5 sensor has a spike for whatever reason, the AQI is slow to respond and spike too, and then it takes forever to return to normal even after normal readings have resumed. Here is a graph of it happening. It is annoying.

Are you using NowCast?

EPA's AQI is based off a 24 hour average. NowCast was developed for more real time data.
