In a domestic construction field, floor surface must be covered not to be scratched and polluted by protector until resident comes in. However this protector restricts the contaminant to leave from floor surface. So when the protector is removed, much contaminant is emitted from the floor surface to inside and makes a bad influence on the indoor air quality, In this research, it will be tested the reduction performance of contaminant between a normal protector and a contaminant absorption protector using charcoal powder.
