The present invention relates to a water-soluble effervescent solid perfume comprising a high content of fragrance which does not include organic solvents such as surfactants, preservatives, and alcohols. In addition, additional components may be carried for cleaning and sterilizing effects, and the effects of fragrance, cleaning, sterilization, and the like may be increased by impartation of an effervescent property. Furthermore, there is no generation of residual by-products after effervescent, and may be processed into a solid formulation, thereby improving stability and improving portability and convenience of use.

A composite virucidal filter media is described. The filter media comprises a fibrous substrate comprising a plurality of intermingled fibers, a low cost, nontoxic, hydrophilic polymer without acidic functional groups deposited on a surface of the fibers without the formation of a continuous coating layer on the substrate, and a virucidal metal, a virucidal metal-containing compound, or combinations thereof deposited on the surface of the fibers comprising the hydrophilic polymer without acidic functional groups. The hydrophilic polymer without acidic functional groups can be charged or non-charged. Methods of making virucidal fibrous filter media are also described.
