Personal inhalation filter
View Patent ↗A cylindrical or other suitably shaped filter container for insertion into a user's nares to filter inhaled air to remove airborne items. The filter container has two open ends forming a container surrounding filter material. Polypropylene may be used to form the container or tube. Other suitable material such as rubber or other softer material may also be used. The present disclosure further includes a respiration mask having a peripheral seal composed of treated and fluffed polypropylene fibers. An edge seal according to the present disclosure lowers the respiratory resistance of a mask and improves the filtration efficiency. Treated, fluffed, polypropylene may also be used to form a respiration mask, such a mask may also include an edge seal to improve filtration and comfort. Treated, meltblown, polypropylene may also be used to form a filter napkin or handkerchief that may be carried and used in short term or unexpected situations.
1. A personal inhalation filter for attracting and capturing bacteria and virus comprising:
a generally planar layer of first filter fibers;
a generally planar layer of second filter fibers having a positive electrical charge, the first filter fibers and the second filter fibers overlapping to form a multilayer filter with the first filter layer forming an exterior side and the second filter layer forming a contact side;
the second filter fibers further comprising polypropylene fibers, wherein the polypropylene fibers have a diameter of about 25 μm;
the polypropylene fibers treated with hexadecytriethylaminonium bromide or dimethyldioctadecylammoniuxn bromide;
an edge filter of fluffed polypropylene fibers having a contact side and an attachment side, the attachment side of the edge filter securing the edge filter along the perimeter of the contact side of the multilayer filter; and
means for securing the multilayer filter to the face of a user.
2. A personal inhalation filter according to claim 1 further comprising:
an adhesive layer coating the contact side of the edge filter.
3. A personal inhalation filter for attracting and capturing bacteria and virus comprising:
a generally planar layer of filter fibers having a positive electrical charge, and an exterior side and a contact side;

the polypropylene fibers treated with hexadecytriethylammonium bromide or dimethyldioctadecylammonium bromide;
an edge filter of fluffed polypropylene fibers having a contact side and an attachment side, the attachment side of the edge filter securing the edge filter along the perimeter of the contact side of the filter fibers; and
means for securing the filter fibers to the face of a user.
