Abstract
The present invention relates to improved protective pleated facial masks or respirators that comprise a pleating spacer that is adapted to enter into, and stably separate the folds of one or more of pleats of a pre-pleated mask or respirator filter, or a pre-pleated filter layer thereof. The present invention also relates to improved protective pleated facial masks or respirators that comprise a pleating spacer that is adapted to stably form one or more pleats in an initially unpleated filter of a facial mask or respirator, or a filter layer thereof. The pleating spacers of the present invention thus act to increase the effective surface area of the filters of such masks or respirators, and thereby improve airflow while preserving the ability of the mask or respirator to protect the wearer from hazardous agents. The invention also pertains to such pleating spacers, and particularly pertains to the use of such pleated facial masks or respirators to protect the wearer from particulates such as dust or other airborne debris, chemical agents, and/or biological agents (e.g., bacteria, fungi, and viruses) from air being inhaled or exhaled by the wearer.
