Woohoo!
We also have this air purifier. It has PM2.5, humidity, and temperature sensors, and will filter your air:

We run that in the bedroom sometimes. All the data, along with the EcoWitt, goes into Home Assistant.
Plus it will kick into higher gear (slightly noisier) if there are too many particles in the air, like when cooking bacon.
