An improved air-conditioner filter, including a planar element for entrapping dust particles, and an additional planar porous element impregnated with a bacteriostat, the filter being arranged in an air-handler unit such that inducted air is first filtered for dust, and subsequently treated for remaining micro-sized organic material. A frame element peripherally encloses the element for entrapping dust particles and the additional porous element so that the components of the filter may be readily replaced as a unit.
