摘要： PROBLEM TO BE SOLVED: To solve the problem with the prior art that an air conditioning system in an ordinary house and a general office building has its chief object of removing larger fine particles utilizing temperature and humidity control and partly utilizing an electric dust collecting machine, and hence it is impossible to remove harmful matters produced from a building material, and also to remove harmful matters which might badly affect a human body such as chemical gas, organic matter, a tick, and a microbe. SOLUTION: Fig. 2 illustrates a typical housing air conditioning system. A chemical filter unit (Fig. 1) for removing harmful gas, organic matter, a fine particle, and moisture is incorporated in response to a removal object, and is disposed at an optimum position with respect to a housing structure. Hereby, air with very high cleanliness is provided to obtain a comfortable indoor space.

摘要： PROBLEM TO BE SOLVED: To eliminate the deformation of the crest part of a filter medium and also a turbulence in the air current and improve the wind velocity distribution and further, prevent the filter medium from being damaged at the crest part by making spacers attached to the surface of the filter medium folded in a zigzag fashion discontinuous at least, at the folded part of the filter medium. SOLUTION: A filter medium 1 is drawn out of a roll 11, then is folded in a zigzag fashion at a folding part 12 and is heated by a heating part 13. In addition, the folded filter medium l is once developed at a development part 14 and a molten spacer material is linearly spewed out of a nozzle 16 by a spacer application part 15 to arrange spacers in a specified pattern. Further the filter medium 1 on which the spacer material is applied, is again folded in a zigzag fashion at a rising part 17 and thus the mini-pleats air filter pack is manufactured. After that, the spacers are attached to both first and second surfaces of the filter medium 1. However, no spacers are attached to the crest part and the valley part of the fold but these parts are formed discontinuously. This discontinuous part is not particularly defined, provided, however, that the crest part is neither of an obtuse angle nor is deformed.

摘要： PROBLEM TO BE SOLVED: To improve unformity of a blowing off air current and miniaturization by a method wherein a filter medium which is composed of a polytetrafluoroethylene porous film, a pressure loss has a specific value, and a PF value to be calculated from a speific collecting efficiency by a specific formula has a specific value, is used. SOLUTION: A performance to be rearly required as a filter medium can be said to be that improvement of a collecting efficiency and a decrease of a pressure loss according to a purpose and place to be used are simultaneously satisfied. The performance to be made numerical by a balance of the collecting efficiency and the pressure loss is a PF value. That is, the filter medium is composed of a polytetrafluoroethylene(PTFE) porous film. Its pressure loss when air is allowed to pass therethrough at a flow speed of 5.3 cm/sec is within a range of 2 to 100 mm H2 O, and more preferably within a range of 2 to 50 mm H2 O. Then, the PF value to be calculated by the formula from the collecting efficiency for which a dioctylphthalate(DOP) of 0.10 to 0.12 μm is used, is at least 8, and more preferably at least 18.
