Seems like the laseregg 2+ at best detects PM2.5, but something like the PurpleAir sensor can detect PM1.0 for roughly the same cost. Have you or anyone else used it? I'm interested in purchasing one.

Are there any of these types of devices that don't need to phone home or be connected to the Internet? The fewer "smart" devices I can have in my home the better.

Iirc the laseregg works fine with no connection. It can be connected, but isn't necessary.

My co2 sensors have no connection either: https://www.amazon.com/Hydrofarm-Autopilot-Desktop-Monitor-L...
