A foam earplug for reception at least partially within the ear canal and including a body portion formed of resilient foam plastic material having a multiple open cell structure and having a size and shape for at least partial reception within the ear canal. A transdermal material having a particular beneficial action, and with an outer layer of the foam earplug infused with the transdermal material so that the benefits of the transdermal material is in transdermal contact with the ear canal. One example is a humectant material and, specifically, a moisturizer/lubricating material, for providing an increase to the lubrication and moisturizing in the ear canal. A second example is where the beneficial action is provided by systemic distribution such as a sleep aid, i.e., Melatonin, so that when the earplugs are worn during sleep, the earplugs will provide a sleep aid to the wearer.

In some examples, a dual mode respirator comprises a face piece; an inhalation port; an exhalation port; and a port closure movable to close the exhalation port and switch the dual mode respirator from a source control mode to a free exhalation mode of the dual mode respirator.

An example method of making a filter for a respirator is provided. An example filter includes a pleated filter element and a preformed filter mounting element for mounting the filter to a face piece or respirator. The method forms a filter having an air impermeable seal extending around a periphery of the filter, the air impermeable seal including and bonded by melted plastic material of the pleated filter element and melted plastic material of the preformed filter mounting element.

An example filter can include a pleated filter element and a preformed filter mounting element for mounting of the filter to a face piece or respirator. The filter can further include an air impermeable seal extending around a periphery of the filter, the air impermeable seal including and bonded by melted plastic material of the pleated filter element and melted plastic material of the preformed filter mounting element.

A pleated molded filtering face piece respirator to be worn upon the face of a wearer and for providing filtering including at least one layer of moldable flexible plastic material formed from openwork flexible plastic material for providing a plurality of perforations for allowing for the free passage of air through the openwork plastic. A layer of moldable filter material for filtering impurities in the air, the one layer of flexible plastic material formed from openwork flexible plastic material and the layer of filter material for filtering impurities in the air lying one on top of the other to form a moldable multilayer of flexible plastic material and filter material. The moldable multilayer of flexible plastic material and filter material are pleated into pleated material and molded to form the pleated filtering face piece respirator to a desired configuration where the one layer of openwork flexible plastic material forms a support layer to carry the layer of filter material.
