The present invention relates to a ventilator, and more particularly to a ventilator in which particulate contaminants are removed.

As industrialization progresses rapidly, air pollution becomes more serious.

In addition, Korea is threatening people's health due to yellow dust coming from China in spring. Yellow dust contains various fine dusts, which can increase the incidence of various respiratory and eye diseases. Therefore, air purification for the prevention of disease is important for vulnerable groups such as patients suffering from heart disease, the elderly, and newborns.

In recent years, people have increased their awareness and awareness of air pollution in the outdoors, but most people are unaware of the seriousness of air pollution in the indoors where most people live.

In particular, indoor air may adversely affect people's lives due to reduced oxygen concentration due to people's breathing or air conditioning.

Therefore, indoor air needs to be periodically ventilated, and when ventilating, it is necessary to purify the introduced air.
