INDOOR AIR QUAILITY

90% of our lives are indoors. Harmful substances in indoor air must be discharged to the outside, and fresh air must flow into the room.

Indoor Air Quality

1. Exhausting contaminated materials in indoor air

2. Supplying fresh air from outdoor into indoor after purifying by air filters

Removal of indoor harmful substances such as viruses generated in the indoor space by using natural or mechanical ventilation facilities

- Open windows and doors, maximize ventilation by using fans and ventilation equipment, etc

- Assistive help in removing harmful substances when using an air purifier

Type of building and ventilation system

  • Offices, shopping malls, hospitals, etc.

Basic principles of ventilation guidelines

  • Ventilation system operation check

  • Maximize outdoor intake

  • Emission of harmful substances before use

  • Internal circulation prohibited

  • Toilet fan always running

An appropriate mix of natural and mechanical ventilation is required.

ventilation through windows
: Days free of fine dust, days that do not consume indoor air conditioning and heating energy, such as spring and fall

Mechanical ventilation
: Days with fine dust, days when heating and cooling energy is used by using indoor air conditioners and boilers in summer and winter
