A maintenance free automatic odor control system comprises a flow through fabric sheet having an attachment end to attach to a forced air heating and cooling register. The attachment end may be a magnetic strip of it may be half of a Velcro(R) pull with the other half mounted on the register. As air is forced through the register, the scent is dispersed throughout the room. Additionally, the fabric is porous and also filters particulates and other impurities from being released into the room by capturing them in the weave of the fabric. The sheets are disposable and are simply replaced and discarded when no longer effective. Because the filter fabric is chosen to be aesthetically pleasing, otherwise unattractive registers may be hidden.
