Abstract: A dehumidifier, which in some embodiments is a wall-mounted dehumidifier, comprising a cabinet, a compressor, an evaporator coil, a condenser coil, a fan, and a bi-polar ion generator. In some embodiments, the cabinet is configured to be installed between studs in a wall. The evaporator is installed within the cabinet above the compressor. The condenser, which may include two or more layers of microchannel condenser coils, is installed within the cabinet above the evaporator. The fan is installed between the evaporator and a back surface of the cabinet. The fan is configured to generate airflow that flows into the cabinet through the evaporator coil and out of the cabinet through the condenser coil. The airflow flows through the evaporator and condenser coils in order to dehumidify the air, and the bi-polar generator generates ions that purify the air, in part by reducing particles, including microbial particles.

Abstract: A warning device of the type that is typically employed to warn pedestrians of a wet floor operates a floor dryer into its design so that, in addition to warning pedestrians of the wet floor, the device may be employed to dry the floor. An air director element produces a beneficial air flow providing increased drying efficacy.

Abstract: A filtered water system for pets that includes two (2) gravity feed units, one (1) of which dispenses filtered water and the other which dispenses dry pet food. The filtered water gravity feed unit includes a breather tube such that when the water level drops below the breather tube level in the water bowl, air enters into the breather tube equalizing the pressure inside and outside of the water bottle. This allows water to fill the water bowl to a level where the pressure inside the water bottle is equal to or less than the pressure on the water in the water bowl and water stops flowing. The water gravity feed unit includes a filter capable of removing some contaminants from the water.
