The high-tech device removes such pollutional and harmful matters as dust, germ and virus from inside room.

Its sterilizing rate is more than 95 percent and absorbing rate of dust particles not smaller than 0.5 micrometer is 90 percent or higher. It also generates a large amount of anion.

The air-conditioner is suitable for rooms which need to be kept germ-free and dust-free.

In particular, the device makes it possible for hospitals to keep their operating rooms germ-free on a very high level and remarkably shorten the period of postoperative treatment while using less or no antibiotic medicines.

Pyongyang Municipal People's Hospital No. 2, Pyongyang University of Medicine Teaching Hospital and many other medical institutions have already benefited from it.
