[Face Bio-Guard] Particle Filtration Efficiency Test #Experimental Video of Vaultcreation

Particle Filtration Efficiency Test_ Experimental Video of Vaultcreation

Comparative test : Vault’s PET filter, KF80/94 mask filter, MeltBlown filter, Nonwoven fabric filter

[Material]

– Vault’s PET filter, KF80/94 mask filter, MeltBlown filter, Nonwoven fabric filter

[Experimental method]

– Installing the test filter in the middle of a cylinder measuring 900mm in width, 70mm in outside diameter(inside diameter 66mm)

– Conduct the experiment by attaching part of rubber gloves to the entrance of the cylinder so that dust can be concentrated into the cylinder

– Prepare 5 cups fo 5 to 10μm dust(1.2g for each test)

– Apply 1.2g dust to each test cylinder

– Spray the blower into each cylinder for 5 seconds(27m/s wind velocity)

– Dust passed through the test filter and smeared in the kitchen towel at the other end

[Result]

– Ranking of blocking efficiency

(1) Vaultcreation PET filter/ KF94mask filter

(2) KF80mask filter

(3) Melt Blown filter

(4) Nonwoven fabric filter
