Reusable head gear with replaceable microfilter assemblies powered air circulation, earthing and communication protocol

A reusable headgear (100), the headgear comprising:

• a) a fan and filter assembly (102) configured to encircle an ambient air in the entire headgear, wherein the fan and filter assembly (102) comprising a multilayered filter assembly (104);
• b) a fan inlet (108) connected to a rechargeable battery and configured to be disposed on a waist of a user;
• c) a strain gauge mechanism (112) comprising a sensor situated below the multilayered filter assembly (104);
• d) a tube housing (114) configured to provide clear visibility;
• e) a head band (116) configured to keep the headgear (100) in place;
• f) a neck band (118) configured to seal the neck and prevent flow of incoming air;
• g) a filter (202) positioned above the neck band (118) and configured to maintain net positive air pressure;
• h) a micro plug and socket assembly (122) positioned at a backside of the headgear (100);
• i) a microcircuit amplifier (128) configured to amplify incoming and outgoing voice signals;
• j) a plurality of external speakers (130);
• k) a pair of dual speakers (132);
• l) a microphone (134) for peer communication;
• m) a foamed earthing cover with metal impregnation, configured to provide aerial earthing for earthing of electrostatic charges through moist air;
• and
• n) a micro plug to connect an anti-static wire mesh tape (124), wherein the anti-static wire mesh tape (124) is configured to ground anti-static charges.
