The fresh air mode is a choice that allows us to breathe in fresh, moist, healthy outdoor air by opening the air duct, this advanced technology is in contrast to conventional air conditioners that only circulate indoor air.
Fresh air ventilation systems are more efficient and healthier because occupants are not at risk of encountering harmful ozone substances through the system. No air purifier can reduce the radon content in a room. At most, some models can measure the radon content in a specific area of a room.
The fresh air system is an independent air treatment system composed of an air supply system and an exhaust air system. It has two types: ducted fresh air system and ductless fresh air system.
