Systems and methods that utilize both UVA and UVC lamps to clean and disinfect a cabin filter of a vehicle, thereby preventing the cabin filter from becoming fouled for an extended period of time. By performing both gas filtration and cabin filter disinfection functions, these systems and methods mitigate: (1) the pressure drop (or flow reduction) experienced; (2) the smell breakthrough when the gas adsorbent becomes saturated; and (3) the presence of microbial growth. This is accomplished by the sequential application of UVC and UVA radiation to the cabin filter, with the UVC radiation being applied for a period of time upon vehicle startup to neutralize bacteria and fungus present in the cabin filter and the UVA radiation subsequently being applied continuously to filter the gas flowing through the cabin filter. A photocatalyst may be added to the cabin filter itself to enhance disinfection and gas filtration.

A honeycomb filter includes a pillar-shaped honeycomb structure body having a porous partition wall disposed to surround a plurality of cells and a plugging portion. The partition wall defining outflow cells includes an exhaust-gas purifying catalyst at least at a part of a region of 0 to 80% of a thickness of the partition wall and includes a portion that does not include the exhaust-gas purifying catalyst in a region of exceeding 80% and being 100% or less of the thickness of the partition wall, and the partition wall defining the inflow cells is not loaded with the exhaust-gas purifying catalyst on the surface, or is loaded with the exhaust-gas purifying catalyst so that a percentage of a ratio of an area of a range loaded with the exhaust-gas purifying catalyst to a surface area of the partition wall defining the inflow cells is 10% or less.

The invention relates to a method for replacing an exhaust aftertreatment component of an exhaust aftertreatment system in a vehicle or vessel. The exhaust aftertreatment system is delimited by an outer casing and comprises a first sleeve, which extends in an axial direction and contains a first exhaust aftertreatment component mounted directly in the first sleeve. The method comprises the steps of: removing the first exhaust aftertreatment component from the first sleeve, the first sleeve thereby remaining intact within the outer casing, providing a second exhaust aftertreatment component being mounted in a second sleeve, the second sleeve being configured to fit within the first sleeve, and mounting the second sleeve with the second exhaust aftertreatment component in the first sleeve by inserting the second sleeve into the first sleeve in the axial direction thereof.
