In the air cleaner according to the third aspect, the cassette 4 containing the pre-filter 2, the ionization unit 3, and the roll 5 is taken in and taken out using the opening 13 of the cleaner body 1 with the lid 14 opened.

(Example) Next, regarding a specific example of the air purifier of this invention,
This will be explained in detail with reference to the drawings.

FIG. 1 is an exploded perspective view of an air cleaner according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a roll 5 of a long filter band 51 and a filter 52 pulled out from the roll 5.

The air cleaner A includes a box-shaped cleaner body 1, a prefilter 2, an ionization section 3, and a cassette 4. The purifier main body l accommodates a blower fan and its driving parts (not shown), and is equipped with an inlet 11 and an outlet 12, and an opening 13 is provided on the side of the purifier main body l. , a lid 14 for opening and closing the opening 13, and a bulge 16 having a viewing window 15 through which the interior can be seen from the front side. The pre-filter 2 has a coarse dust collection function, and is provided with a handle 2I at one end thereof. The ionization section 3 has a function of ionizing fine dust, smoke, oil, etc. in the air, and has a recess 31 extending almost the entire height at one end thereof. Cassette 4
, a holder 44 in which a pair of semi-cylindrical bodies 41 and 42 are connected by a hinge 43, a lattice frame 45 provided on the semi-cylindrical body 41 on one side, and a ground wire mesh provided on the semi-cylindrical body 42 on the other side. 46, and the holder 44, lattice frame 45, and wire mesh 46 can be opened and closed around the hinge 43. Note that an opening 47 is formed in the semi-cylindrical body 42 of the holder 44.

When the cassette 4 is inserted into the purifier body 1, the holder 44 is accommodated in the bulge 16 of the purifier body 1, and at the same time, the opening 47 of the holder 44 faces the viewing window 15 of the bulge 16. It looks like this.
