A bacteria-killing filter device is suitable for air-conditioning equipment, and includes a bacteria-killing filter screen, a macromolecular substance filter screen and a small molecule substance filter screen which are sequentially stacked. The germ-killing filter is used to eliminate pathogenic sources in the air to produce disease-free substances. The macromolecular substance filter is used to filter the macromolecular substances in the disease-free substance, and finally the small molecule substance filter is used to filter the disease-free substances. Small molecular substances can effectively filter the outside air through multi-layer filtration to achieve the effects of deodorization, virus elimination, and bacteria elimination.一種滅病菌過濾裝置，適用於空調設備，包括依序層疊設置的滅病菌過濾網、大分子物質過濾網與小分子物質過濾網。滅病菌過濾網用以消滅空氣中的致病源，以生成無病菌物質，大分子物質過濾網用以過濾無病菌物質中的大分子物質，最後由小分子物質過濾網過濾無病菌物質中的小分子物質，藉由多層過濾方式可有效過濾外界空氣，以達到除臭、滅病毒、滅細菌等功效。
