  • Air purifier with dual exit paths
    Patent number: 10926210
    Abstract: An air purifier including an air filter, an air movement device configured to move air at least partially in an axial direction and through the filter, and a first exit path in fluid communication with the air movement device. The first exit path is configured such that at least part of the air moved by the air movement device exits the first exit path generally in the axial direction. The air purifier further includes a second exit path in fluid communication with the air movement device and configured such that at least part of the air moved by the air movement device exits the second exit path at an angle of between about 10 degrees and about 45 degrees relative to air exiting the first exit path.
