[0002]

2. Description of the Related Art Conventionally, there is a filter between a filter and a main body housing, which is hermetically sealed by a frame of a molded article such as PP. This phenomenon has a drawback in that the sucked dirty air is discharged from the discharge port. In the conventional configuration,
Depending on the product, short-passing occurs easily depending on the molding conditions and combination of the molded product, and there is no stable collection efficiency (efficiency that shows how much dust is collected in one pass). There is also a drawback that the toner is liable to adhere and the user becomes uneasy because of being dirty. Further, there is a drawback that the short path as described above is easily generated due to a defect such as the user not replacing the filter depending on how the user uses the filter by replacing the filter.

The conventional air purifier can exhibit its original performance by purifying dirty air with a filter of a main body housing. However, the space between the main body housing and the filter is not sealed, and a short path (dirty air) is not provided. However, there is a problem that dirty air is discharged from the discharge port.
