Sensor for furnace air filter replacement (lemmy.world)

Is anyone aware of a sensor (preferably Zigbee, I think), that will give me an idea of when I need to change my furnace air filter?

I am picturing something that maybe sits on the "clean" side of the filter to measure...pressure? Air quality? I don't know.

Yeah, there's no sure fire way to know without checking. Simpler solution is a calendar reminder every month to look at it 🤣

Honestly though, you can get cheap air sensors that will at least tell you if the PM rises in the house. Won't alert to things that might be giving you allergy problems though.
