Using a fiber having a basis weight of 40 to 150 g / m 2 and a thickness of 0.1 g / m 2 .
The use of a filter medium of 29 to 0.48 mm is preferred. When the average fiber diameter is less than 5 μm, there is a disadvantage that the pressure loss increases, and when the average fiber diameter exceeds 70 μm, there is a disadvantage that the collection efficiency decreases. Also, the basis weight is 40
If it is less than g / m 2 , there is a disadvantage that strength sufficient to reinforce the main filter medium cannot be obtained, and the basis weight is 150 g / m 2.
If it exceeds m 2 , there is a disadvantage that the workability of pack processing (bending of the filter medium) is deteriorated. Also, if the thickness of the filter media is 0.2
If the thickness is less than 9 mm, there is a disadvantage that sufficient strength to reinforce the main filter medium cannot be obtained, and the thickness is 0.48 m.
If it exceeds m, the filter medium is too thick, and the workability of pack processing (folding of the filter medium) is disadvantageously deteriorated.

う不都合がある。As the melt-blown non-woven fabric filter material used as the main filter material constituting the cleaning and regeneration type air filter of the present invention, organic fibers made of a single substance or a mixture of polypropylene, polyester, Teflon (registered trademark) and the like can be used. Using fibers with a diameter of 4-6 μm,
The basis weight is 50 to 80 g / m 2 and the thickness is 0.18 to 0.30 m
It is preferred to use m filter media. When the average fiber diameter is less than 4 μm, there is a disadvantage that the pressure loss is not recovered when washing is performed twice or more, and when the average fiber diameter is more than 6 μm, there is a disadvantage that the washing efficiency is reduced when washing is performed twice or more. Further, if the basis weight is less than 50 g / m 2 , there is a disadvantage that the pressure loss is not recovered by washing twice or more, and the basis weight is 80 g / m 2.
If it exceeds m 2, if it is washed twice or more, there is a disadvantage that the workability of pack processing (bending of the filter medium) deteriorates. Also,
If the thickness of the filter medium is less than 0.18 mm, it is difficult to bond the filter medium, and there is a disadvantage that the filter medium is easily broken by itself. If the thickness exceeds 0.30 mm, the filter medium becomes thick,
There is an inconvenience that the workability of pack processing (bending of the filter medium) is deteriorated.
