The present invention in one or more embodiments provides an oil filter adaptor to engage an oil filter, where the oil filter adaptor includes a base and a neck extending from the base in a first direction and to engage the oil filter, the neck including a wall defining therein a passageway extending at least partially in the first direction, the wall defining thereupon a through-aperture extending in a wall thickness direction. The oil filter adaptor of the present invention may pre-discharge oil flowing out thereof when the oil filter is removed, avoiding oil splashing due to an otherwise large efflux of oil in a very short period of time.

A water purifying filter has a cylindrical inner housing to receive a filter therein, and an outer housing to receive the inner housing. The inner housing and the outer housing are spaced apart from each other to form an insulation space configured to suppress heat transfer and to reduce the filter freezing inside the inner housing.
