A cleaning assembly for reusable filters comprises a housing and a pressurizing spraying assembly that receives a filter element to be cleaned. The pressurizing spraying assembly can be secured in position relative to the housing using a mount. The mount can pivot about a pivot axis between a storage position and a use position. The pivot axis can be aligned with a handle axis about which a handle is attached to the housing. The housing can collect runoff from a cleaning operation.

An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter includes a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium includes a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame includes a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

An apparatus and method for cleaning ash/soot and other particulates from diesel particulate filters (DPF), including diesel oxidative catalysts (DOC) and similar exhaust components. Section for dry and wet cleaning include conduits that connect to the filters. For dry cleaning, a filter is mounted clean side up and air pressure is applied in opposite directions so that the particulate is dislodged and falls out. For wet cleaning, the filter is floated with a slug of liquid cleaning solution which is surged back-and-forth through the filter to dislodge and remove the particulate. The dry and wet cleaning sections may be combined or collocated, or may be located separately or used one without the other.

Various embodiments of the present disclosure can include a system for filtering of contaminated fluid. The system can include a fiber manufacturing plant. The system can include a filter system which utilizes a fiber filter produced in the fiber manufacturing plant to clean and recycle a contaminated fluid.

An air conditioner indoor unit includes an electric control box, a cleaner device, and an electrical wire. The cleaner device includes a filter screen rail assembly and a cleaning assembly configured to drive a filter screen to move on the filter screen rail assembly to clean the filter screen. The cleaning assembly includes an electrical wire connection end. The electrical wire is arranged at the cleaning assembly and the filter screen rail assembly. One end of the electrical wire is connected to the electrical wire connection end, and another end of the electrical wire is connected to the electric control box.

A wash hood for a baffle-type grease filter and a pollution control system for cleaning baffle-type grease filters outside or inside without contaminating the environment or soaking the operator with cleaning solution. The hood includes ridges on the inside for supporting the filters at an angle to a rear wall. A channel around the ridges guides the effluent towards a drain hole. A separator box with a filter connected to the drain hole separates the grease from the water such that the water may be discharged into a mop sink connected to a sanitary sewer system.
