Is the new house fresh air system in in addition to formaldehyde?
In addition to formaldehyde doesn't need a fresh air system. The fresh air system can remove indoor formaldehyde. The fresh air system continuously exhausts indoor polluted air including formaldehyde through continuous air supply and return air, and continuously sends outdoor air into the room after cleaning, which can effectively remove formaldehyde volatilized from indoor furniture. Installing a fresh air system is equivalent to installing a green "lung" in the house, which can ventilate the room without opening the window for 24 hours, and strongly expel toxic gases such as formaldehyde, benzene and ammonia in the room to protect human health.
