Abstract: A water purifier and a filter for the water purifier are provided. The water purifier includes a raw water flow path formed to bring in raw water from the outside, a purified water flow path connected to the raw water flow path for the raw water to flow in a first direction, a filter located in the purified water flow path to filter the raw water, a bypass flow path branched from the purified water flow path for the raw water to bypass the filter and connected to the purified water flow path on a downstream side of the filter in the first direction, a washing flow path branched from the bypass flow path and connected to the purified water flow path on a downstream side of the filter in the first direction, and a drain flow path connected to the filter to guide the raw water flowing into the filter to a second direction. The filter includes a raw water inlet through which raw water flowing in the first direction is introduced, a purified water outlet through which purified water filtered is released, and a drain outlet through which wash water having washed the filter is discharged.
