An indoor unit for an air-conditioning apparatus includes a cartridge provided to an air inlet so as to be freely mountable and dismountable. The cartridge accommodates a filter so as to be freely movable in a right-and-left direction and has an opening port formed in one end portion in the right-and-left direction. A dust box is provided on a side of the end portion of the cartridge. The dust box includes a cleaning mechanism configured to clean the filter and a dust collecting portion configured to collect dust.

In general, embodiments of the present invention are related to an apparatus and method of use of such apparatus for the personal filtration of air. Particularly, embodiments of this invention relate to the filtration of air for a singular individual to inhale.

An apparatus and a method for isolating and/or preparing particles are provided.

An apparatus and a method for isolating and/or preparing particles are provided.

A method for filtering airborne particulates is described. The method includes providing an exhaust hood, and the exhaust hood defines an intake and the exhaust hood being adapted to receive airborne particulates via the intake. The method also includes conveying a portion of a filter media from a media source area to an active media area, transferring the portion of the filter media from the active media area to a media discard area, the media discard area and the media source area being disposed on substantially opposed sides of the active media area, and severing the portion of the filter media in the media discard area from a remainder of the filter media.

A system and method for automatically cleaning air filters of a medical imaging system is provided. The method includes monitoring an air filter operating condition, determining that the air filter operating condition is not within a pre-determined threshold, and providing a control signal to at least one air filter. The at least one air filter comprises a motor, drive shaft, rotatable passive shaft, continuous belt air filter, and a stationary filter brush. The drive shaft is rotatably coupled to the motor. The continuous belt air filter is coupled to the drive shaft and the passive shaft. The stationary filter brush is mounted against the continuous belt air filter. The method includes rotating, by the motor in response to the control signal, the drive shaft to translate the continuous belt air filter around and between the drive shaft and the rotatable passive shaft, and across the stationary filter brush.

Methods and systems are provided for regeneration of a particulate filter including a filter body having a filter paper looped along a plurality of rolling guides. At least one rolling guide may be a roller heater having a motor and a heater. Activation of the roller heater based on a pressure difference across the particulate filter regenerates the particulate filter during a regeneration phase and positions a regenerated section of the filter paper for trapping soot in a subsequent soot loading phase.
