Definitions

  • the object of the present invention is a new oral-nasal hygienic mask equipped with independent and interchangeable nasal and oral filters.
  • CoVid-19 disease An important route of transmission of the CoVid-19 disease occurs through the inhalation of contaminated particles from body fluids that are released involuntarily when talking, coughing or sneezing. Due to their very small size, these particles remain suspended in the air for long periods of time, being able to later be inhaled by other people who, in this way, are infected with the disease.
  • hygienic masks are made up of a single piece that covers the user's mouth and nose. Naturally, being a single piece, these masks also cover a large part of the user's face around the mouth and nose.

This new mask thus reduces the covered area of the wearer's face. Furthermore, by having interchangeable fixing means of independent filters for mouth and nose, it is possible to replace said filters separately depending on the specific needs of each case. Furthermore, this allows the use of different filters for the user's mouth and nose if the user's respiratory characteristics so advise.
