Abstract: The presently disclosed subject matter is generally directed to a device that is releasably or permanently mountable on at least one blade of a conventional ceiling fan to reduce the number of particulates in the air. Specifically, the device cooperates with a filter to remove a wide variety of impurities from the air, such as dust, pollen, smoke, pet dander, and the like. The disclosed system comprises a device and a filter. The device includes a support that provides a base for the attachment of the filter. The device further includes an adaptor that cooperates with a series of joints to allow the size and shape of the support to be customized for a particular ceiling fan blade. Advantageously, the device can be coupled to a wide variety of ceiling fan blades to enable an associated filter to clean the air as the fan blades rotate, thereby reducing the number of particulates in the air.
