Beschreibung
Zusammenfassung:	A device that can accurately detect clogging of a filter and that has a simple structure is provided. A device for measuring clogging of a filter in an air conditioner (2) having a blower (30) that blows gas (40), (42) through a duct (10) and a filter (20) that is provided in the duct (10) and filters dust floating in the gas, comprises a device (26) for measuring a sound pressure that is provided in the duct (10), a data processor (70) that extracts data on the sound pressure at a specific frequency from the data on the sound pressure that have been measured by means of the device (26) for measuring a sound pressure, and an estimating device (70) that estimates clogging of the filter based on the data on the sound pressure at the specific frequency that have been extracted by means of the data processor (70).
