The present invention relates generally to methods for the delivery of beneficial respirable compounds such as moisture, anti-inflammation compounds, anti-irritants, fragrances, aromatherapy compounds, and low dose medications slowly and continuously over time using a mask containing a thickened aqueous gel media delivery system combined with, supported by, and coating solid bodies inside the filter. The present invention also relates generally to methods for the removal of harmful industrial gasses from inhaled air using a disposable filtration mask containing a fluid filter media composed of a thickened aqueous gel that can be readily modified by means of additives to enhance its filtration properties for specific gasses individually, or in combination. The fluid filter media is combined with, supported by, and coats solid bodies inside the filter which optimize contact between the fluid filtration gel and the incoming air containing harmful industrial gasses. The present invention also relates generally to methods for the removal of hydrophilic bio-particulates from inhaled air using a disposable filtration mask containing a fluid filter media composed of a thickened aqueous gel that wets the bio-particulates, increasing their effective size and mass, and then retains them using the surface tension and viscosity of the thickened aqueous gel.La présente invention concerne de manière générale des procédés d'administration de composés respirables bénéfiques comme de l'humidité, des composés anti-inflammatoires, des anti-irritants, des fragrances, des composés d'aromathérapie et des médicaments à faible dose, lentement et en continu au cours du temps au moyen d'un masque contenant un système d'administration fait d'un milieu de gel aqueux épaissi combiné avec, supporté par, et recouvrant des corps solides à l'intérieur du filtre. La présente invention concerne également de manière générale des procédés d'élimination de gaz industriels dangereux de l'air inhalé au moy
