A hand held vacuum having a tapered centrifugal chamber as its primary filter. The tapering causes the air stream within the centrifugal chamber to accelerate as it moves toward the distal end. The air steam will be able to retain more debris at higher speeds, thereby improving the efficiency of the centrifugal chamber. This will also keep more of the debris in the vicinity of the distal end of the centrifugal chamber and away from its outflow aperture. An air freshener in a filter housing is also provided. The air freshener will sublimate into the passing air stream and be emitted with the exhaust from the vacuum and / or any odor causing particles that may be in the air stream will be absorbed by the air freshener. The filter will prevent any dust and debris in the airstream from adhering to the air freshener and impeding its effectiveness.

A plant air purifying enclosure, or “PAPE,” contained within an unconditioned space, either within or outside a building, containing therein a plant air purifier, which is used to purify air using plants and microbes growing therein. The PAPE enclosure itself receives poor indoor quality air from within structure where the PAPE is located or from a structure close by along with thermal energy which keeps the plant air purifier enclosure at a suitable temperature for the plants and air cleaning microbes within the air purifier. Poor air enters the enclosure, is purified by the plants and microbes, and returns in purified form back to the habitable space from which it was taken. This lowers the amount of outside air needed for ventilation purposes and so lessens a building's overall energy consumption while providing efficiently for naturally purified air. Fundamentally, the object of this invention is to specify devices, systems and methods to house / enclose plant purifiers in such a way that they can readily be deployed on a wide scale.

An air freshener clip removably engages with a louver or slat of a vent, such as an automotive heating and air conditioner vent. The clip has a curved body that tapers from a clip bend at its proximal end to a tip at its distal end. When the clip is engaged over the louver or slat, the distal end of the curved body extends into the vent opening. The air freshener clip has an outer portion formed from one or more fragrance loaded polymers, and releases fragrance into an air stream that contacts the outer portion on the curved body and is directed out of the vent. An accessory may be removably attached or link to the clip to decorate or adorn the clip.

The present invention combines an air freshener that has a source of air freshening chemical with a fan that is controlled either by an optical device that senses light or a motion detector. When a light is turned on or motion is detected, the fan will be activated for a predetermined time period. In certain embodiments, the fan will stop turning after a predetermined time. Alternatively, the fan can continue to be powered until the light source is turned off (or all motion ceases), and only then either immediately shut down, or shut down after a predetermined time period. In certain preferred embodiments the source of air freshening chemical is disposed beneath the fan and allows fragrance to be delivered over time without the fan. The additional airflow provided by the fan causes more volatile fragrance chemicals to be removed from the source of air freshening chemical and admitted into the environment. The fan motor of the present invention is driven by a power source, such as batteries, AC line current or alternate sources such as solar cells. Preferably, a microprocessor controls the fan so that a “burst mode” is created by controlling the frequency and intensity of the pulses of air freshener that are emitted.
