Presented is a portable hand held e-cigarette shaped oxygen generator and air purifier. The device includes a suction body through which atmospheric air is forcibly introduced within a main body of the device during respiration, a solid oxygen filter adapted for holding solid oxygen, and a solid oxygen filter support having a dual cylindrical structure for housing and supporting the solid oxygen filter. The device further includes a solid oxygen filter support lid mountable over the solid oxygen filter support and is adapted for discharging device generated inhalable oxygen from the main body to a micro filter, a casing embodying the micro filter and operationally connected to a mouthpiece having an extension for mounting a straw. The atmospheric air introduced in the device reacts with the solid oxygen to generate inhalable oxygen after passing the atmospheric air through the dual cylindrical structure of the solid oxygen filter support.

A process for converting post-explosion gases of an inhabitable level, low-oxygen ambient environment to a breathable mixture for human consumption comprises receiving a flow of post-explosion gas with oxygen, carbon dioxide, carbon monoxide, nitrogen, and methane. The oxygen, carbon monoxide, and carbon dioxide are removed from the from the flow of post-explosion gas to create both a mixture including oxygen, carbon monoxide, and carbon dioxide; and a residual stream including nitrogen and methane. The oxygen is removed from the mixture of oxygen, carbon monoxide, and carbon dioxide, and concentrated in a primary oxygen storage canister. The nitrogen is removed from the residual stream and stored in a nitrogen storage canister separate from the oxygen storage canister. The methane is vented back to the inhabitable level, low-oxygen ambient environment. The stored oxygen and nitrogen are metered through a breathing mask at a habitable level of 19-21% oxygen to a user.
