Air purifier apparatus with flexible filter modules

A portable air purification apparatus comprising:

• an air supply module configured to provide a stream of compressed air;
• a facial mask;
• at least one toxin sensor configured to evaluate an ambient environment for a presence of at least one toxin and generate a toxin signal in response to a detected presence of the at least one toxin;
• an air supply conduit, wherein the air supply conduit includes a plurality of integrated membrane filter devices, wherein each of the plurality of integrated membrane filter devices having a first interface and a second interface, the first interface configured to be selectively coupled to either the air supply module or the second interface of another one of the plurality of integrated membrane filter devices, and the second interface configured to be selectively coupled to the facial mask or the first interface of another one of the plurality of integrated membrane filter devices, each of the plurality of integrated membrane filter devices having an air-impermeable flexible housing disposed between the first interface and the second interface of each of the plurality of integrated membrane filter devices, the flexible housing encasing one or more filtering fibers suitable for filtering one or more contaminants from the stream of compressed air;
• and
• an oxygen supply module, wherein the oxygen supply module includes at least a solid oxygen sequestration composition and an oxygen liberation device, the oxygen liberation device selectively activated by an oxygen generation signal to provide oxygen from the oxygen sequestration compound to an oxygen inlet port of the air supply module;
• wherein the oxygen generation signal is generated by one or more control processors, wherein the one or more control processors are configured to generate the oxygen generation signal in response to:
• receiving the toxin signal from the at least one toxin sensor,
• comparing the detected toxin against a stored record of toxins that are filterable by at least one of the plurality of integrated membrane filter devices, and
• determining that the detected toxin is not suitable for filtering by at least one of the plurality of integrated membrane filter devices.
