Abstract
A media basket assembly for use with an air purifier, such as but not necessarily limited to media basket assembly suitable for use with a vertical airflow type of air purifier. The media basket assembly may include a filter media configured to filter the airflow and a basket for positioning the filter media relative to a lower fan shroud of the air purifier.
Claims13
A media basket assembly for use with an air purifier, comprising:
- a filter media configured to filter airflow through the air purifier;
- and
- a basket configured to attach to a lower fan shroud of the air purifier, the filter media being disposed within an interior volume of the basket, wherein the basket includes a plurality of apertures to direct airflow through the filter media and the basket includes a shutter configured to selectively cover one or more of the plurality of apertures, the shutter including one or more windows interspersed between one or more shields.
A vertical airflow air purifier comprising:
- a housing;
- a divider separating an interior volume of the housing into an upper chamber and a lower chamber, the divider including a central opening to provide an airflow passageway between the upper and lower chambers;
- a motorized fan assembly disposed within the upper chamber above the central opening, the motorized fan being configured to draw air from the lower chamber;
- a fan shroud disposed between the fan assembly and the divider, the fan shroud having a covering portion configured to cover a cross-sectional area of the central opening, the covering portion including a plurality of gaps to permit airflow therethrough;
- and
- a media basket attached to the fan shroud, the media basket including a basket filter media to filter airflow passing through the gaps, wherein the media basket includes an elongated carrier top connected to a planar carrier bottom, the basket filter media being disposed within a confined space created between the carrier top and the carrier bottom, the carrier top includes a plurality of elongated arms configured to attach the media basket to the fan shroud, the arms extending longitudinally from an outer surface of the carrier top in a direction away from the basket filter media, and each arm fits through one of the gaps such that a bracket at a distal end thereof snap fits overtop of an interior surface of the fan shroud to provide a compressive fit between the outer surface of the carrier top and an exterior surface of the covering portion.
