Abstract
An antiallergen filter of the present invention is characterized in that a water-insoluble high-molecular weight anti-allergenic agent having a phenolic hydroxyl group and a moisture-absorbing material are carried on a filter. Because of using the water-insoluble high-molecular weight substance as an anti-allergenic agent, the antiallergen filter of the present invention is free from a problem that the anti-allergenic agent flows and drops or is detached from the filter due to moisture in the atmosphere, etc. even in a highly humid environment or the like. Further, since the moisture-absorbing material is carried on the filter, moisture that the anti-allergenic agent requires for adsorbing and capturing an allergen and inactivating its allergic activity can be effectively retained on the filter. Thus, the antiallergen filter of the present invention can effectively exert its anti-allergenic effect over a prolonged period of time.
