Embodiments of passive air pollution filters designed for providing efficient adsorption of fungal spores, airborne bacteria, small hydrocarbons, viruses, prions, insect parts, hyphal parts, pollens, other allergens, radon gas, and other small air pollutants, both gaseous and particulate, from cool air are disclosed. Each embodiment comprises a filter bag portion, attractant mineral, a filter container, and a means of supporting the filter assembly. Stationary filters must be replaced and reprocessed periodically. Permanent passive air filtration coatings for building materials, which prevent condensation and growth of mold from occurring in building walls and in other structures, are disclosed. Automated temperature pump passive filtration devices, which automatically remove excess humidity, odors, particulate air pollutants, both mineral and biological, gaseous air pollutants, and allergens from enclosed volumes of air at a temperature of less than 26-27° C., about 80° F., are also disclosed.
