Publication number: 20150182766Abstract: A nasal air filtration device includes a pair of either planar or concave-convex filters, a support structure incorporating a pair of generally annular bases or sleeves for supporting the filters, and a bridge that couples the bases or sleeves to maintain them in a desired spaced-apart relation and to determine a desired angular relationship. The support structure is insertable into the nasal cavities to position the filters within corresponding nasal cavities. Flexible rims maintain the support structure and the filters in spaced-apart relation to the surrounding nasal wall. The filters may be placed within the bases at an angle with respect to the walls of the bases. Also, the filtration device may be flesh tone in color, thereby blending with the skin tone of the user. In some embodiments, a post structure is supplied for supplying a scent or aroma to the wearer.Type: ApplicationFiled: September 15, 2014Publication date: July 2, 2015Inventors: David M. Dolezal, John D. Wilder, Daniel M. Gelfman

Patent number: 8424526Abstract: A holder for a nasal air filtration device or dilation device. A holder for a nasal device may be a thin, generally “Z” or “S” shaped device that holds a nasal device in a substantially secure and stable position. Each of a nasal device's nasal bases can be placed or secured on a placement limb of the holder while a connecting member of the nasal device can be secured on the opposite side of the holder from where the nasal bases are positioned along a vertical portion of the holder relative to the placement limbs. There may be securing notches in the holder that help secure a nasal device at generally the point where the bases of the nasal device attach to the connecting member of the nasal device. The notches may allow a nasal device to be securely attached to the holder.Type: GrantFiled: December 31, 2009Date of Patent: April 23, 2013Assignee: AirWare, Inc.Inventor: David M. Dolezal

The support structure is insertable into the nasal cavities to position the filters within corresponding nasal cavities. Flexible rims maintain the support structure and the filters in spaced-apart relation to the surrounding nasal wall. The rims conform to surrounding nasal tissue to form seals. The rims can be selectively inclined to facilitate insertion and resist accidental removal. In certain embodiments the device is combined with a filter that covers the mouth to provide an air filtration system.Type: GrantFiled: September 29, 2005Date of Patent: April 5, 2011Assignee: AirWave, Inc.Inventors: David M. Dolezal, John D. Wilder, Daniel M. Gelfman

Patent number: 7156098Abstract: A nasal air filtration device includes a pair of concave-convex filters, and a support structure incorporating a pair of generally annular bases for supporting the filters, and a bridge that couples the bases, to maintain them in a desired spaced-apart relation and to determine a desired angular relationship between the bases and between the associated filters. The support structure is positionable against the anterior nares to direct the filters into their corresponding nasal cavities. The support structure maintains each of the filters in spaced-apart relation to the surrounding nasal wall. In alternative embodiments, an open frame is mounted to each base and positioned between its associated filter and the nasal wall.Type: GrantFiled: March 19, 2004Date of Patent: January 2, 2007Assignee: Dolezal Creative Innovations, LLCInventors: David M.
