> - Cooking is insanely bad for the air in your house

Hold on! Not all particulates are equally harmful - and by far!

A particulate sensor detects water vapor or particles of (non-burnt) cooking oil that are harmless to humans.

In the same way, it detects very dangerous (carcinogenic) compounds from combustion engines or burning coal or wood.

Cooking is in no way "insanely bad" (unless you are grilling your food black or cooking on an open wood/coal fire)
