Abstract: Disclosed is a re-usable an integrated wearable suit (100) including battery powered ventilation for providing protective shield with complete safety from viral and bacterial loads, and a transparent head shield (102), a microphone (116) with dual speakers (118) for peer communication, a microsensor (107) for filter clogging sensing, alarm display device and amplifier connected to re-chargeable battery backup (108), a torso (120) including chain covered with a sealable flap facilitating the opening and closing of the kit, a lower body part (136) extending from mid hip to ankle and shaped for movement comfort of both legs and bending and sitting freedom, a pair of shoes covers (138) with a gripped bottom (140), with earthed anti-static and low voltage safety and a plurality of restricted one way air outlets (142).

Abstract: The present invention relates to a re-usable head gear (100). The re-usable head gear (100) includes a fan and filter assembly (102), a replaceable multi-layered filter assembly (104), air leakage proof housing (106), a fan inlet (108) a strain gauge mechanism (112), a tube housing (114), a head band (116), a neck band (118), a low voltage wiring (120), a micro plug and socket assembly (122), an anti-static wire mesh tape (124), a customized hybrid microcircuit amplifier (128), external speakers (130), high clarity hi-fidelity dual speakers (132), and a microphone (134).

Abstract: A multi-layered replaceable filter assembly (100) and a microfilter assembly (200) for providing safety from external exposure. The multi-layered micro filter assembly includes plurality of filter membranes. A first filter membrane (104) prevents particles greater than 10 micron from entering the multi-layered replaceable filter assembly (100). A second filter membrane (106) has embedded activated carbon that destroys micro-organisms including viruses and bacteria. As we go further downstream, the fiber density per cm keeps increasing with the filter membranes. A fifth filter membrane (112) made up of a combination of crabyon fiber and electro-spun nano fibers provides comfort and anti-allergic effect. A sixth filter membrane (114) lowers the velocity of air that occurs from breathing and a method thereof.
