Compared to air conditioning, fresh air systems may be a relatively new concept for many people. The reason why it can enter people’s sight is because in recent years, smog has become increasingly severe, and it has also brought a large amount of PM2.5 into people’s lives. Especially in autumn and winter, which is already a high-risk period for respiratory related diseases, coupled with severe pollution weather, the elderly, children, and even healthy adults are facing great threats! In the city, a breath of clean and fresh air is really rare.

What is a fresh air system?
Some netizens may have already installed central air conditioning in their homes and believe that there is no need to install a fresh air system, as they feel that the functions are conflicting. Actually, the fresh air system and central air conditioning are completely different things.
Simply put, central air conditioning is aimed at temperature control in enclosed spaces, which means circulating the air inside the home to solve the problem of heating and cooling. But the fresh air system takes in fresh air from outside, introduces it into the room, and exhausts the indoor air to achieve air exchange without opening windows, which is called external circulation.
Why install a fresh air system?
Can we just open the window for ventilation? Nowadays, there are more and more severely polluted weather in cities, so it is not recommended to open windows. Moreover, during the autumn and winter seasons, when cold outdoor air enters the room, it directly lowers the indoor temperature, which can easily make people sick.
