At the time of c, a filter of 0.1 to 10 mmAq is generally used.
In a filter in which activated carbon is impregnated and an electret is combined, the pressure loss is 5 mmAq (air volume 5 cm 3 /
cm 2 / sec), but the amount of activated carbon is about 50
g / m 2 , the deodorization life was short. Also,
Those using urethane were expensive. In addition, a filter in which pellet-shaped activated carbon is packed in a honeycomb-shaped hexagonal column has a problem in that the flow of air is disturbed, and when an electret is used in combination, the flow of air is uneven and the dust removal performance is reduced.

The impregnated activated carbon is made acidic by impregnating phosphoric acid or the like to improve the deodorizing effect of ammonia or the like. The larger the particle size of the activated carbon, the lower the pressure loss, but if the particle size is less than 10 mesh, the activated carbon will crack. If the particle size is more than 100 mesh, the activated carbon will be detached when forming the filter member, making it difficult to manufacture. In addition, although the deodorizing performance is better as the amount of the activated carbon is larger, the sealing strength between the nonwoven fabrics is reduced when the amount of the enclosed carbon is 400 g / m 2 , so that the non-woven fabric cannot be used.

These show the characteristics of a filter for an air purifier obtained by pleating a filter member according to the present invention and an electret filter, and FIG. 2 shows characteristics of dust removal performance and deodorization performance with respect to filter pressure loss. FIG. 3 and FIG. 3 are characteristic diagrams showing the required power capacity and pressure loss of the fan for maintaining the air flow of 5 cm 3 / cm 2 / sec. As shown in FIG. 2, the characteristics of the dust removal performance and the deodorization performance of the filter depend on the pressure loss of the filter, and if the dust removal performance and the deodorization performance are improved, the pressure loss increases. On the other hand, the air volume of an air purifier is approximately 5 cm 3 / c for a home air purifier.
m 2 / sec, and in order to maintain this air volume,
As shown in FIG. 3, as the pressure loss increases, the fan power capacity of the air purifier increases. Therefore, the filter member of the present invention is generally used for household air purifiers, the maximum fan power capacity is 40 W, and the dust removal performance is 7%.
It was set so that the deodorizing performance was 0% or more and the deodorizing performance was 50% or more. That is, from FIG. 2, the pressure loss when the dust removal performance is 70% or more and the deodorization performance is 50% or more is 0.5 mmA.
The pressure loss is 10 mmAq when the power capacity of the fan is 40 W from FIG. 0.3 to 4 mmAq, which is obtained by subtracting 0.2 to 6 mmAq of electret filter pressure from 0.5 to 10 mmAq of total pressure loss of this filter, was set as the range of pressure loss of the filter member of the present invention.

ものとすることができる。As described above, the filter member according to the present invention is a filter member formed by sandwiching activated carbon and a binder between air-permeable nonwoven fabrics, and has a pressure loss of 5%.
0.3 to 4 m when the air volume is cm 3 / cm 2 / sec
The size of the activated carbon particles is set to 20 so as to obtain mAq.
80 to 200 g / m 2 , the amount of the binder is 30 to 50 parts by weight with respect to 100 parts by weight of the activated carbon, and the breathable nonwoven fabric is made of a thermoplastic fiber selected from polyester fibers and rayon fibers. Since the specific gravity is 0.02 to 0.1 g / cm 3 , the pressure loss can be reduced, and the dust removal performance and deodorization performance can be improved.
