Abstract: The present invention relates to a laundry machine and a controlling method, which can remove allergens on the laundry. A controlling method of a laundry machine includes a mite-killing step of supplying seam to a drum to make laundry exposed to a hot environment at or over a temperature and for or over a duration of time, wherein the temperature and the duration are predetermined enough to kill house dust mites on the laundry; a rinsing step of rinsing the laundry; and a spin-drying step of spin-drying the rinsed laundry. The present invention has an advantageous effect of removing allergens including house dust mites, animal hair and pollens efficiently. In addition, if the house dust mites are killed by using steam, energy efficiency is high and an effect of mite-killing is great.
