    • A disposable portable mask for emergency use in a contaminated atmosphere is disclosed, which mask comprises a sponge of adequate size to cover a user's mouth and nostrils. The sponge is impregnated with water or an aqueous solution of an acidic salt, or weak alkali salt, for adsorption of toxic acidic gases passed therethrough. Perfume may be included in the sponge to mask any disagreeable odors of the sponge or liquid materials employed. The liquid-containing sponge is compressed and sealed within a fluid-tight container of plastic, or the like, to prevent evaporation of the liquid from the sponge. The overall package is of small size for ease in carrying in a person's pocket, handbag, or the like, so as to have a mask available for ready use at all times with a minimum of inconvenience. For use in case of an emergency, the mask is removed from the container and placed over the person's mouth and nostrils for adsorbing toxic gases breathed therethrough, preventing inhalation thereof. Securing means for attaching the mask to the user's face may be provided to free the hands of the user for other uses. The entire mask simply is disposed of after use.
