Kits for consumer activated hydrogel air fresheners are provided, comprising an acrylic resin, a fragrancing material, and a coloring agent. The kit may take various forms, such as a container in which are packaged the appropriate amounts of resin, fragrance, and colorant, to which a volume of water is to be added. In another form, the kit may comprise a sachet or pad containing the above materials, to which water may be added to form a gel air freshener device. Further, a pad or sachet, containing the hydrogel resin and a coloring agent if desired, may be subjected to the controlled continuous feed of a water solution of a fragrance, whereby a long term, consistent fragrancing is obtained.
