摘要： Provided are an air filter medium that can be reused with a small decrease in performance by performing a disinfection treatment, a pleated pack, an air filter unit, a mask filter medium, and a method for regenerating an air filter medium. An air filter medium (30) including a fluororesin porous membrane (31) and a supporting member (32) stacked on top of each other has a permeability ratio (permeability after disinfection treatment/permeability before disinfection treatment) of 5.0 or less, the permeability ratio being a ratio of permeabilities of the air filter media (30) before and after the disinfection treatment of the fluororesin porous membrane (31) as determined using NaCl particles having a particle size of 0.1 µm, and a pressure loss ratio (pressure loss after disinfection treatment/pressure loss before disinfection treatment) of 0.83 or more and 1.15 or less, the pressure loss ratio being a ratio of pressure losses of the air filter media (30) before and after the disinfection treatment of the fluororesin porous membrane (31).

摘要： Die Erfindung betrifft ein Filtermaterial (10) zur Luftfiltration in einem Filterelement (100) und ein Filterelement aus solchem Filtermaterial.
Das Filtermaterial (10) ist mit einer anströmseitigen Vorfilterlage (2), einer Aktivkohlelage (3) und einer Verbundlage (1) ausgestattet, welche als Feinfilterlage mit Nanofasern ausgebildet ist. Erfindungsgemäß sind die Lagen stoffschlüssig miteinander verbunden.
Dank der Kombination von Vorfilterlage und Verbundlage mit Nanofasern in einem Filtermaterial wird in vorteilhafter Weise gleichzeitig ein hohes Staubspeichervermögen bei hohem Qualitätsfaktor erreicht.
