The answer is yes. We used to say that air was free. Now it seems that fresh air is not cheap either. For the formaldehyde, PM10, PM2.5, and TVOC in indoor air, let's discuss their harm to people.
Formaldehyde is particularly common in home decoration. Floors, cabinets, wooden doors, curtains, sofas, and so on will release formaldehyde. And they continue to be released for 3 to 15 years.
Formaldehyde is particularly harmful to the respiratory tract and facial mucosa, which is easy to induce bronchial asthma and aggravation of allergic dermatitis, causing nasopharyngeal tumors. Formaldehyde poisoning can cause loss of appetite, insomnia, dream, memory loss, and other symptoms. It is especially harmful to pregnant women, young children, and the elderly, which may lead to developmental deformity and cancer in young children. It is internationally recognized as a class of carcinogens.
PM10 is particulate matter in the air with a diameter of 10μm or less. Most PM10 can be directly inhaled by the respiratory tract, but part of the body can be discharged through sputum, in addition, it will be blocked by the villi inside the nasal cavity, and the harm is relatively small.
PM2.5 refers to particulate matter in the air with a diameter of 2.5μm or less. Because it is relatively small, it can directly enter the lungs and blood, can cause respiratory diseases, light is tracheitis, bronchial infection, serious can cause pneumonia, pneumoconiosis, etc., serious can lead to lung cancer. In addition, it will also affect the endocrine system of the human body, which will have a certain impact on human immunity.
TVOC refers to total volatile organic compounds, is the VOC (indoor organic gaseous substances) general term. TVOC can cause dysregulation of the body's immune level and affect the function of the central nervous system, resulting in self-conscious symptoms such as dizziness, headache, drowsiness, weakness, and chest tightness. Also may affect the digestive system, loss of appetite, nausea, serious damage to the liver and hematopoietic system, and even cancer.
To sum up, air purifiers are necessary to use and will be paid more and more attention to.
