A respirator mask, having a face cup shaped to cover a nose and a mouth of a user, the face cup having a face seal for providing an airtight flexible seal around the nose and mouth of the user, the face cup having at least one respiration port therethrough; a filter for filtering particulate elements from air, the filter received in an inhalation passage formed through the face cup by the at least one respiration port to filter air passing through the inhalation passage; and an accessory housing secured to the face cup to hold a mask accessory, the accessory housing being shaped to receive at least one accessory therein.

The present invention relates to the field of air filtration, in particular to a polytetrafluoroethylene composite filter material and a preparation method and uses thereof. The polytetrafluoroethylene composite filter material comprises a support layer and a polytetrafluoroethylene microporous membrane layer, and the support layer and the polytetrafluoroethylene microporous membrane layer are compounded by an adhesive, wherein the adhesive comprises a two-component polyurethane adhesive, a pore forming agent and an inorganic filler. The present invention adopts a two-component solvent-free polyurethane adhesive, and by adding a low-temperature pore forming agent and an inorganic filler, the pore forming agent forms an irregular pore channel structure at the bonding interface during curing, and the inorganic filler prevents the adhesive from entering the micropores of the polytetrafluoroethylene membrane, so that the air permeability and filtration efficiency of the polytetrafluoroethylene microporous membrane are not affected after compounding; and the prepared polytetrafluoroethylene composite filter material has good air permeability, high peel strength, good filtration efficiency and good barrier effect.

Face mask including a mask body, lining around an edge of the mask body, and a nose strip, wherein the complete face mask including the mask body, the lining, and the nose strip is made of a single recyclable material, such as PET. The face mask can be ground directly for recycling without first separating the parts of the face mask.

A face and neck cover includes a fabric tube having an inner surface and a droplet filter attached to the inner surface. The droplet filter includes a first filter layer, a second filter layer joined to the first filter layer along a first fold, and a third filter layer joined to the first filter layer along a second fold. The third filter layer is in contact with the inner surface of the fabric tube. A first filter pocket for holding an optional removable filter medium is formed between the second filter layer and the third filter layer. A second filter pocket is formed between the third filter layer and the inner surface of the fabric tube. The first, second, and third filter layers are preferably integrally formed from one continuous sheet of fabric folded and attached to the fabric tube.

An article and method for using the same is disclosed. The article is worn on a user's head and secures a mask to the user's face without requiring loops associated with the mask to be worn over the back of the ears of the user, thereby eliminating strain and discomfort on the user's ears.

A mouth protection device for a respiratory protection system, in particular a blower respiratory protection system, comprises at least one mask base body which is configured to cover a mouth and/or nose region of a user and which delimits a breathing zone at least partially, and comprises at least one breathing air supply line, which is connected to the mask base body and delimits at least one breathing air channel that ends in the breathing zone and is configured for guiding an active breathing air flow,

wherein the mask base body is made at least largely of a flexurally soft material, the mask base body being made at least largely of a textile material.

The present invention relates to the field of air filtration, in particular to a polytetrafluoroethylene composite filter material. The polytetrafluoroethylene composite filter material comprises a supporting layer and a polytetrafluoroethylene film layer, wherein the supporting layer is a silver-plated carbon nanomaterial-modified meltblown nonwoven fabric. The polytetrafluoroethylene composite filter material is prepared by fiberizing a resin material modified by silver-plated carbon nanomaterial on the surface of a polytetrafluoroethylene film by a melt-blowing method. The polytetrafluoroethylene composite filter material of the present invention combines filtering and sterilizing functions, has higher filtering efficiency and filtering precision, has the functions of sterilizing and killing viruses, has a good isolation effect, and greatly prolongs the service life of the filter material.

A mask for covering at least a nostril and a mouth of a wearer. The mask includes a main body portion and an ear hooking portion attached to the main body portion. At least a part of the main body portion has a sheet-like piezoelectric portion, and the piezoelectric portion includes a yarn formed of an electric field forming filament.

A mouth cover includes a mouth cover body that covers at least the mouth and the nostrils of a wearer, and wearing portions that are connected to the mouth cover body and allow the wearer to wear the mouth cover body. The mouth cover body includes an opening in a downward direction from a position directly facing the mouth of the wearer.

The present invention relates to customized personality attachment devices that are configured to display customizable images, words, or phrases to non-verbally convey messages, feelings, or an individual's state of mind. The attachment devices have one surface having a message or image and an opposite surface having an adhesive, hook/loop, or magnetic layer enabling the attachment device to removably attach to one or more of at least face masks, earrings/rings, canisters/cups, shirts, hats/caps, walls, refrigerators, office/school boards, garages, and surfaces such as, but not limited to, helmets, shoes, purses, backpacks, car seats, head rests, the side of vehicles, clothes, customizable identifiers and so much more. The devices are washable and, depending upon placement of the devise, can be made from various types of material including photoluminescent, cotton, vinyl, polyester, polyethylene, polycarbonate, felt, twill, nylon, a variety of other plastics and materials.
