A nasal air filtration device for filtering air inhaled by a user is disclosed. The nasal air filtration device includes a pair of nostril tubes including a filter at one end and an ionic plate at other end. Each of the nostril tubes includes a cup having a plurality of openings. The nasal air filtration device includes a base tube coupled to the nostril tubes. The base tube includes an exhaust channel. The base tube includes a first housing having a battery and a second housing having a fan. In order to filter the air inhaled by a user, the nostril tubes are placed inside nostrils of the user. When the user inhales, the fan is operated to draw the air into the base tube, and the air is made to pass through the filter and the ionic plate provided at the nostril tubes into the nostrils via the openings. When the user exhales, the air is released into the atmosphere through the exhaust channel via the nostril tubes.

Disclosed is a nasal mask assembly. An example mask assembly includes a first part, a filter, a second part, and at least two straps attached to the second part. The first part includes a base configured to engage the face surface around a nose of a user and a filter support extending from the base and defining a breathing chamber. The filter support includes a first outlet and at least one first inlet. The filter is placed over the filter support and covers the first inlet. The second part can be configured to engage the base and a portion of the filter support around the first outlet and to cover a combination of the filter support and the filter. The second part includes a second outlet and a second inlet configured to be positioned against the first outlet.

A nasal insert may include a wall in the shape of a tube, the wall including a first end defining a first orifice and a second end defining a second orifice. The first end may have a diameter, diagonal measurement, or cross-sectional area larger than that of the second end. The first end may define at least one break in the wall, so that the first end incompletely encircles the first office. The second end may completely encircle the second orifice.

Respiratory devices and methods for their manufacture and use are disclosed. The device features a resiliently deformable element configured to form a perimeter seal with the inner nostril wall and to swab the distal portion of the internal nostril region with a disinfectant during device installation. A first filter stage includes a first filter layer characterized by first geometric convolutions and a first MPPS1 value; and a second filter stage includes a second filter layer characterized by second geometric convolutions and a second MPPS2 value.

Devices and methods of inhibiting the inhalation of particulates using a resiliently deformable filter packaged in a sealed envelope containing a liquid medium. The method includes opening the sealed package to thereby expose the filter to ambient air; removing the filter from the package; inserting the filter into a distal region of a nostril; and urging the filter from the distal region to a proximal region of the nostril while simultaneously swabbing the distal region with the liquid disinfectant. The filter includes: an initial stage characterized by a first pore size; an intermediate stage characterized by a second pore size; and a final stage characterized by a third pore size, wherein the third pore size is a smaller than the first and second pore sizes.
