A method of manufacturing a respiratory nasal filter comprising: laying down a base layer which has a first side including an adhesive, and a second side; laying down a non-woven fabric filter layer; cutting a skin-safe pressure sensitive adhesive into two strips; affixing the two strips of skin-safe pressure sensitive adhesive to the non-woven fabric filter layer; cutting the non-woven fabric filter layer bonded to the two strips of skin-safe pressure sensitive adhesive into an oval; cutting an inner oval out of the base layer whereby the inner oval cut out of the base layer is smaller than the oval cut out of the non-woven fabric filter layer; aligning and laying down the base layer onto the oval cut filter layer concentrically such that the filter layer covers the inner oval that was cut out of the base layer; and cutting an outer oval out of the base layer whereby the outer oval cut out of the base layer is larger than the oval cut out of the non-woven fabric filter layer creating a nostril filter.
