A nasal filtration apparatus configured to be releasably secured around a nose of a user and provide filtration of air inhaled therethrough. The present invention includes a body having a wall manufactured from a filtration material or layers thereof such as but not limited to polypropylene. The body includes a central support member extending down the middle thereof from the upper edge to the lower edge of the body. The central support member is malleable so as to permit shaping of the body to form a cavity that will accommodate a user's nose therein. The nasal filtration apparatus includes a perimeter edge that is formed and includes material thereon that provide a releasable securing thereof to the skin of the user. A first nostril insert and second nostril insert can be included to provide additional and/or application specific filtration.

Intra-nasal filter devices and methods for their manufacture and use are disclosed. An intra-nasal filter device includes: a first stage filter proximate the septum; and a second stage filter comprising a flexible material extending upwardly from the first filter stage filter; wherein the flexible material comprises: an impedance in the range of 0.02 to 0.2 cmH.sub.2O; an effective cross-sectional area in the range of 0.2 to 2 square inches; and a plurality of radially extending geometric structures disposed along an axial length of the second stage.

Face masks configured to fit over a nose and a mouth of a user wearing an eyewear article. The face masks include a cover and an eyewear coupler. The cover is configured to the cover the nose and the mouth of the user. The eyewear coupler is attached to the cover and configured to selectively attach to the eyewear article to couple the cover to the eyewear article. In some examples, the face mask includes the eyewear article to define a face-and-eye-mask.

Proposed is a mask inserted into a nasal cavity, and more particularly, to a nose mask equipped with a filter that can be inserted into a nose to filter various fine dust contained in external air that is inhaled into the nose during respiration, and provide antibacterial and far-infrared emitting effects to improve health of a respiratory tract.

A breathing filter assembly for filtering breathing air includes a breathing unit that includes a mouthpiece that can be placed in a user's mouth. The breathing unit includes a pair of nose tubes that can each be positioned in a respective one of the user's nostrils when the mouthpiece is positioned in the user's mouth. A filter is removably insertable into the breathing unit. The filter is comprised of an air permeable material to pass air therethrough for breathing. The filter extends into the mouthpiece and each of the nose tubes to filter air inhaled through the user's mouth or the user's nose.

An intranasal cannula apparatus for use to filter air that enters a nasal cavity of a user is provided. The apparatus includes a pair of elongated bodies coupled together and designed to insert in the nasal cavity of the user. Each elongated body has a front portion, a rear portion, a top portion, a bottom portion and side portions that form an internal cavity therein. Each elongated body has a nasal opening disposed on the bottom portion of the elongated body that aligns with one of the nostrils of the user. A dorsal opening is disposed on the top portion of each elongated body. A pair of filters is disposed within the pair of elongated bodies. The apparatus is designed to permit air from the nostrils of the user to pass entirely through the nasal openings and dorsal openings in the elongated bodies to the nasal cavity of the user.
