An ultraviolet disinfecting cartridge system comprising:
- an ultraviolet disinfecting cartridge comprising:
- a) a flow channel extending from an inlet to an outlet for receiving a flow of breathing air and comprising an interior surface that has dimples;
- wherein the inlet and the outlet are aligned along a length axis of the ultraviolet disinfecting cartridge;
- b) a UV light emitter configured along said interior surface of the flow channel and configured to emit ultraviolet light into the flow channel;
- c) an inlet adapter configured to couple with a ventilator hose;
- d) an outlet adapter configured to couple directly with an inlet opening of a face mask;
- e) an inlet filter configured proximal to the inlet of the flow channel;
- f) an outlet filter configured proximal to the outlet of the flow channel;
- g) an ionizer that emits charged particles and is configured proximal to the inlet of the flow channel;
- h) an ionizer collector configured proximal to the outlet of the flow channel that removes charged particles from the flow of breathing air;
- wherein the ionizer collector is detachably attachable to the ultraviolet disinfecting cartridge;
- i) a reactive material configured in the flow channel, said reactive material comprising a photocatalyst configured to react with pathogens in the presence of the ultraviolet light emitted by the UV light emitters to increase pathogen disinfection;
- j) six or more baffles extending from the interior surface of the flow channel substantially orthogonal to the length axis of the ultraviolet disinfecting cartridge to produce orthogonal flow channels within the flow channel to increase the resonance time of the flow of breathing air from the inlet to the outlet;
- k) a flow assist fan configured to produce said flow of breathing air through the flow channel and wherein the flow assist fan is configured proximal to the inlet of the flow channel;
- wherein a portion of the plurality of UV light emitters are configured within the orthogonal flow channels and configured to emit ultraviolet light into the orthogonal flow channels;
- wherein a first UV light emitter of the plurality of UV light emitters emits a first UV light having a narrow band wavelength of 220 nm +/−5 nm to neutralize pathogens and a second UV light emitter of the plurality of UV light emitters emits a second UV light having a second wavelength between 250 nm and 280 nm to destroy pathogens;
- wherein the UV light is configured to destroy or neutralize pathogens in said flow of breathing air;
- wherein the dimples on the interior surface are configured to produce a random dispersion of reflected UV light;
- and
- wherein the ultraviolet disinfecting cartridge system has an allergen removal efficiency of 99.9% or more air purification;
- wherein the ultraviolet disinfecting cartridge system utilizes a combination of two UV wavelengths, ionization and ozone by-product to achieve a disinfection of 99.9% or more of pathogens.
