Why do we need a fresh air system in our home?

In the cold winter when you can't open the window for ventilation, you can ventilate 24 hours a day.

Without opening the window, force the filtered fresh air from the outside in.

Efficiently prevent and remove haze to prevent haze from harming the health of your family.

Remove indoor formaldehyde through ventilation.

Prevent outdoor odors from entering and remove indoor musty odors, oil smoke and other odors.

Eliminate indoor bacteria and viruses: The indoor environment is clean and hygienic, and bacteria and viruses have nowhere to hide.

Avoid air conditioning and heating diseases: Ventilate without opening the window, and keep the room fresh and oxygen-rich at all times.

Prevent furniture and clothing from getting moldy: Keep the air circulating indoors, so that excess moisture can be evaporated and discharged, keeping it dry and comfortable.

Why not just open the window for ventilation?

Although opening the window for ventilation is free, there are many problems:

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

It is cold outside in winter, so it is not practical to open the window for ventilation;

The noise outside directly enters the room;

The ventilation volume is uncontrollable, either there is no wind or the wind is too strong;

You cannot open the window when turning on the air conditioner/heater;

It is not safe to open the window if there are children at home;
