Title:

FILTER MEDIUM FOR AIR FILTER, AND AIR FILTER UNIT USING THE SAME

Document Type and Number:

Japanese Patent JP2021112694

Kind Code:

A

Abstract:

To provide a filter medium for air filter extremely superior in deodorizing speed and excellent in adsorption capacity under the kinetic condition in which air is circulated like an air filter.SOLUTION: A filter medium for air filter of this invention includes a layer including a granular gas adsorbent having an average particle diameter of 250 μm or less between two nonwoven fabric sheets. In the filter medium, a ratio of the average particle diameter of the granular gas adsorbent to the thickness of a layer including the granular gas adsorbent is 0.85 or more, and a pressure drop of the layer including the granular gas adsorbent at an air velocity of 6.5 m/min is 4.0 Pa or more.SELECTED DRAWING: None
