First, the principle and function of the new fan

Fresh air fan is a kind of equipment that filters and purifies outdoor fresh air and introduces it into the room, and at the same time discharges the indoor dirty air. Its core features include:

Ventilation: The fresh fan introduces fresh outdoor air into the room through mechanical ventilation, and at the same time discharges the indoor dirty air to realize the circulation and exchange of indoor and outdoor air.

Air purification: Fresh air fans are usually equipped with multi-layer filtration systems, such as primary filters, HEPA filters, activated carbon filters, etc., which can effectively filter pollutants such as particles, bacteria, viruses, and harmful gases in the air.

Temperature and humidity adjustment: Some high-end fresh fans also have a heat exchange function, which can adjust the temperature and humidity of the air while introducing outdoor air to maintain the comfort of the indoor environment.

2. Sources and hazards of indoor odors

Indoor odor mainly comes from the following aspects:

Decoration pollution: In newly renovated houses, harmful gases such as formaldehyde, benzene, and TVOC are the main sources of odors, and long-term inhalation of these gases may lead to respiratory diseases, allergic reactions and even cancer.

Kitchen fumes: The fumes produced during the cooking process not only produce odors, but may also contain carcinogens, which can affect indoor air quality.

Pet odor: Odor and excrement on pets can also produce odors, which affect living comfort.

Tobacco smoke: The smoke produced by smoking contains a large number of harmful substances, which not only produce odors, but also cause serious health hazards.

Damp and musty smell: It is easy to breed mold in a humid environment, producing a musty smell, and long-term inhalation may lead to respiratory diseases.

Indoor odors not only affect living comfort, but can also cause adverse health effects, such as headaches, dizziness, nausea, allergic reactions, etc. Therefore, it is crucial to address the problem of indoor odors.
