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.
