Title:
RESPIRATOR AND AIR PURIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/089465
Kind Code:
A1
Abstract:
A respirator(100) includes a face mask (130), a porous filte r(230) comprising a filtration material, an air flow system (120) in fluid communication with the porous filter(230) and the face mask (130), and an oxidant generator(850) configured to produce at least one oxidant. The air flow system (120) includes an enclosed container (121) and a blower (310) housed within the enclosed container (121). The air flow system (120) is configured to generate a flow of air such that ambient air passes through the porous filter (230) to the face mask (130). At least one contaminant in the flow of air is adsorbed by the porous filter (230), and the filtration material catalyzes an oxidation reaction between the oxidant and the contaminant to promote decomposition of the contaminant on the porous filter (230). According to another aspect, provided is an air purification system including at least one respirator (100) and a decontamination device (800).
