Water filter having a filter use time indicator

The described embodiments of the present invention include a water filter having a float portion with a magnet that moves up and down due to water flow to activate a switch for tracking the use time of the filter.

Hinge down refrigerator water filter

A refrigerator water filter assembly is provided in the ceiling of a refrigerator and is adapted to hinge downwardly from the ceiling for changing the filter cartridge. The cartridge is normally partially recessed within the ceiling so as to minimize the use of space in the food compartment of the refrigerator. The filter assembly includes a base mounted in the refrigerator ceiling, a manifold pivotally mounted on the base, a filter cartridge attached to the manifold, and a cover pivotally mounted on the manifold so as to be movable between open and closed positions. When the cover is opened, the filter cartridge is angled downwardly from the ceiling for easy grasping by a person for replacement of the cartridge.

Dust collector with an inbuilt cyclonic water filter

A dust collector with an inbuilt cyclonic water filter, comprising a cup-shaped dust collecting unit, a water filter, a fan, a dust passage, an air flow passage, incoming and outgoing air passages; wherein, the outlets of the water filter open into the inlet of the outgoing air passage, and the outlet of the outgoing air passage is separated from the incoming air passage, passes through the outer wall of the cup-shaped dust collecting unit and is connected to the air flow passage. In operation, dust-containing air enters the dust collecting unit via the incoming air passage at a tangent, and the air flow in the dust collecting unit is whirled downwards into the water of the water filter, thereby, the dust contained in the air is wet and left in the water, while purified air is discharged.
