Ventilation system is a very good choice for people who are inconvenient to open windows, areas with poor air quality all year round, people who are prone to allergies, patients with respiratory diseases, the elderly, pregnant and young, people with mysophobia and those who are worried about formaldehyde pollution. If possible, ventilation system is a good choice. Just pretend.

Why install ventilation system instead of directly opening windows for ventilation?

Although it is free to open windows for ventilation, there are many problems:

1. PM2.5, dust, car exhaust, and industrial waste gas in the outside air will enter the home.

2. It’s cold outside in winter, so it’s not practical to open windows for ventilation.

3. Noise from outside enters the room directly.

4. The ventilation volume is uncontrollable, there is either no wind or too much wind.

5. Do not open windows when turning on air conditioning/heating.

6. If there are children at home, it is not safe to open the windows.
