An internal combustion engine exhaust modification system for transforming exhaust emissions from an internal combustion engine into modified exhaust emissions. The exhaust modification system includes a housing extending between inlet and outlet ends thereof. The system also includes an impeller rotatably mounted in the housing, and a filter subassembly downstream from the impeller. The filter subassembly removes part of particulate matter and liquid droplets in the exhaust emissions to transform the exhaust emissions into modified exhaust emissions. The system includes a conduit extending between an inner end thereof positioned to direct cooler air exiting therefrom into the housing toward the filter subassembly, and an outer end thereof. The system also includes a funnel subassembly having a funnel body for directing the cooler air into the outer end of the conduit.

A coating material mist remover of the present disclosure includes: a first duct that discharges air containing coating material mist from an outflow port directed downward; a second duct having an inflow port opened in a horizontal direction; and an incinerable intermediate filter that is detachably connected between the first duct and the second duct and removes the coating material mist from the air. The coating material mist remover also includes: a first connection mechanism that can connect and separate the first duct and the intermediate filter; and a second connection mechanism that can connect and separate the second duct and the intermediate filter.

Provided is a cooking apparatus including: a main body; and a ventilator comprising a ventilator body including an inlet configured to inhale air containing oil mist generated in a cooking process using a heating device, a blower configured to blow the inhaled air from the inlet; and an oil mist filter positioned inside the ventilator body, and configured to remove the oil mist by filtering the oil mist from the inhaled air.

A liquid separator for separating liquid out of a gas/liquid mixture, including an inlet, an outlet, a flow path connecting the inlet to the outlet and at least one separating device arranged in the flow path, the liquid separator being designed and embodied with simple structure and a compact construction to enable reliable separation of liquids in such a way that the separating device has a fabric portion for liquid separation through which the flow path passes, the fabric portion being arranged at an angle of 1° to 15° relative to the main flow direction in the separating device.

Proposed is a multi-layer filtration system including a metal catalyst filter unit, a carbon filter unit, and an inorganic compound filter unit. The metal catalyst filter unit includes at least one among metals including Ni, Co, Fe, Cu, Cr, Mg, Zn, Ba, Au, Ag, Pd, Pt, Ru, Mn, and Ti, oxides thereof, and mixtures thereof. The carbon filter unit includes at least one of activated carbon or activated carbon fiber. The inorganic compound filter unit includes an inorganic compound capable of adsorbing toxic gas. The multi-layer filtration system has good removal effect for toxic gas. A filter module including the multi-layer filtration system and a gas mask including the multi-layer filtration system are also proposed.
