    摘要： An air filter unit in which the generation of organic substances is restrained by controlling at least the amount of organic substances detected from a square test piece of 5.times.5 cm (25 cm.sup.2) of a filter medium so as to be 100 ng or less in the total amount of organic substances detected from the whole air filter unit at a temperature of 40.degree. C. before using. The air filter unit is assembled by housing a filter medium that has been bent in a waveform in a frame composed of 4 outer frame members and sealing the gap between the frame and the filter medium using a sealing compound. Organic substances adhering to the air filter unit are removed by blowing a cleaned air heated at 80.degree. C. against the air filter unit at a velocity of 50 ml/min for 60 minutes. Then, an air suction port and an air exhaust port of the air filter unit are sealed with a film (for example, a PET film) which keeps the unit from contacting with organic substances and from which organic substances are not generated.

    摘要： The present invention provides a novel group of particles for air filter inspection which solves problems caused by volatilization and scattering of those particles at the downstream side of the air filter in use, enables an air filter inspection with superior stability and reproducibility, and may be produced by using a comparative inexpensive manufacturing device, and manufacturing methods as well as inspection methods of such a group of particles. The group of particles for air filter inspection consists of a plurality of aggregate particles having a particle size of not less than 0.1 &mgr;m, each aggregate particle being constituted by solid primary particles having an average particle size of less than 55 nm. Further, the inspection method for an air filter has the steps of: producing the group of particles by atomizing and drying a suspension containing the solid primary particles having the average particle size of less than 55 nm, introducing the group of particles into the upstream side of the air filter, and detecting any of the group of particles leaked out of the downstream side of the air filter with a particle detector.
