A filtration media including at least a first nonwoven fabric having at least one meltblown layer in provided. The at least one meltblown layer includes a plurality of meltblown fibers having an average diameter from about 1 to about 5 microns. Methods of making a filtration media are also provided. Facemasks including such filtration media are also provided.

An air filter including a filter support that supports porous, polymeric sorbent particles that comprise a divalent metal impregnated therein.

A protective device that includes a combined mask and face shield. The mask and face shield are attached together to form a continuous member that extends across the face of a user. A continuous seal extends around the exterior of the device including the mask and face shield.

A protective facemask includes: a facemask panel sized to cover at least a user's nose and mouth including at least one layer of filter material, where the facemask panel is generally rectangular having a pair of side edges with a vertical height and including folded pleats in the filter material running along the width of the facemask panel; and an elasticized headband panel fixed to an extending between the side edges of the facemask panel, where the vertical height of the headband panel is substantially the same as the vertical height of the side edges of the facemask panel where the panels are fixed to each other

Disclosed herein are methods and systems for face mask with replaceable filter cartridges and components. A face mask includes a mask component, a replaceable filter component, and a closure component. The replaceable filter component is bonded to and as between the closure component and the mask component when the closure component is attached to the mask component.

The multifunctional facemask is intended to improve on conventional facemask devices through an innovative facemask design that is designed to provide a convenient means of carrying while incorporating other problem-solving features. In other words, the device is designed to be rolled up, folded, or carried in a compact form, so as to be worn on the user's wrist as a fancy handkerchief or snap bracelet, when not being used as a facemask. To accomplish this, the device preferably uses buttons to secure the mask device to the wrist. More specifically, the device includes a flexible mask member and a face attachment member. The device further includes one or more fastening elements that can engage with the face attachment member, so as to enable the user to carry the facemask on the user's wrist or elbow. Thus, the multifunctional facemask is a user-friendly face mask device with improved functionality.

Various embodiments of a respirator and a method of forming a respirator are disclosed. The respirator can include a mask body having an upper panel, a lower panel, and a central panel disposed between the upper and lower panels. The mask body can also include a left attachment mechanism disposed between a left tab of the mask body and a left portion of at least one of the upper panel and the lower panel when the mask is in an open condition, and a right attachment mechanism disposed between a right tab of the mask body and a right portion of at least one of the upper panel and the lower panel when the mask body is in the open condition.

A disposable face mask includes an upper portion of the face mask and a lower portion of the face mask, the upper portion and lower portion of the face masks each adjoin monolithically formed therewith face mask straps defined by perforations in a web of material used to form the face mask and straps, wherein the perforations allow the straps to be partially separated and utilized for securing said face mask to a wearer's face. The disposable face mask may be made by perforating patterns into a web of materials to define the face mask straps and face mask body that are formed monolithically from the web of materials. The face masks may be wound on a roll for dispensing by tearing off from the roll and then separating the straps at the perforations. Alternatively, the face mask borders may be cut-through to allow dispensing of the face masks individually from bulk packaging, where the face mask is removed from the package and the straps are separated at the perforations to allow the face mask to be secured to the wearer's face by tying the straps behind the wearer's head.

An improved impression wheel for use within respiratory face mask manufacturing machines that includes a first, second, and third series of spaced helicoidal teeth shaped and adapted to more efficiently and securely interconnect respective layers of respiratory face masks.

A heated medical face mask is provided, including, a first outer layer having an outer surface and an inner surface; a second, inner layer having an outer surface and in inner surface; the first and second layers being fastened together around corresponding peripheral side and bottom edges but being open along an upper edge or side edge to form a pocket; and a heating element being releasably located in the pocket.
