An industrial air pollution control device that uses filter bags to capture dust and particles from exhaust gases.
From 'bag' (filter medium, usually made of fabric) + 'house' (structure or chamber). Modern industrial term from the 20th century as factories sought ways to reduce air pollution.
Baghouses are boring metal boxes, but they're everywhere—in coal plants, cement factories, grain mills—silently catching billions of dust particles every day, preventing them from reaching your lungs!
