A pressure detector for detecting the pressure of the air passing through the air filter, and an alarm that indicates clogging of the air filter when a predetermined difference occurs between the output value of the pressure detector and a reference value. An air filter clogging alarm featuring: (2) A duct that is installed inside the housing and on the back of the air filter and has a small hole in a part, a tube that connects to the small hole of the duct, a U-shaped manometer that connects the tube with one end, and this U-shaped manometer. a thermistor located in a U-shaped manometer whose resistance value changes depending on the liquid of the U-shaped manometer that changes with the pressure change of the air passing through the air filter; and an indicator light or sound device connected to the thermistor and serving as a load. Utility model registration claim No. 1 (1) characterized in that it is equipped with an amplifier having
Air filter clogging alarm as described in ).
