The present invention relates to a protective face mask and filtration article, a method for using a protective face mask and filtration article, and a design for manufacturing. In particular, the invention relates to a self-contained, mobile, battery-powered bioactive and filtering breathing appliance that provides broad spectrum antimicrobial and allergic protection via an atomized biocidal agent steam/vapor and a torturous hydrophilic filtration article that sterilizes incoming air and captures debris. To this end, antimicrobial activity and filtration functions leverage a redundancy of means/methods comprised of antimicrobial hydrogen peroxide liquid/vapor/steam and an iodized salt containing hydrophilic filtration article. The present invention is a wearable apparatus that sterilizes incoming air by capturing, neutralizing and destroying airborne pathogens and other particulate matter and pumps sterilized oxygen/air for natural, unlabored breathing by the wearer. The present invention further relates to a production method thereof.

The invention relates to the respiratory organs protection technical means that provide human with life support in the atmosphere unsuitable for breathing. Insulating breather with closed breathing mixture circulation loop (self-contained self-rescue, SCSR) is equipped with a cylinder (15) containing pressurized oxygen. The breather has increased effectiveness of the treatment of the exhaled gas mixture and improved quality of the inhaling gas mixture by using the breathing mixture circulation loop of the present invention and using means for simultaneous mechanical pressing on the breath-out bag (4) and the breath-in bag (8) and the additional cooling.
