Whether the fresh air system is an IQ tax product? Let me tell you if you have installed it at home. How do you feel about using it?

The fresh air system is not as good as imagined. It only replaces the air in the house twice a day, but the fresh air system can always achieve a certain effect, especially when the windows cannot be opened. There is no way to add a fresh air system later, so it is recommended to install it during the renovation!
