Ask HN: What do you use for air quality monitoring?
2 comments
I recently bought a furnace hepa filter and slapped it in front of a fan I have. Red laser light and sun beams missing is telling me it works. My cat also seems to appreciate it.

Do the sensors need Internet access or can they send to something on the local network?
