What should I do if formaldehyde exceeds the standard

When people are exposed to excessive formaldehyde for a long time, it will do a lot of harm to health. Long-term low-concentration exposure to formaldehyde can cause headache, dizziness, fatigue, sensory disturbance, decreased immunity, drowsiness, memory loss or neurasthenia and mental depression. Chronic poisoning is extremely harmful to the respiratory system. Long-term exposure to formaldehyde will lead to respiratory dysfunction and toxic lesions in the liver, such as liver cell damage and abnormal radiation energy in the liver.

When formaldehyde exceeds the standard, the main treatment methods can be:

1. Ventilation method: Window ventilation is a traditional and commonly used method. The existing temperature of formaldehyde needs to be above 19 degrees to effectively control the volatilization, and the higher the temperature, the faster the volatilization. Even in hot weather in summer, closing windows during the day and ventilating at night are ideal ventilation methods. When all doors and windows are opened, you can choose to use the floor fan as an assistant, start the swing mode, blow air at the window, realize direct flow, exchange indoor and outdoor air with maximum efficiency, and make formaldehyde smell faster.

2. Adsorption of formaldehyde by activated carbon: The principle of air purification by activated carbon depends on its developed pore structure and surface area, which can contact with the surrounding air to a great extent and passively adsorb some pollutants into its own pores. The advantage of activated carbon is that the price is also relatively economical. Activated carbon can only absorb harmful gases such as formaldehyde and cannot be decomposed. Under limited conditions, it is easy to cause secondary pollution after adsorption saturation, and it needs to be replaced after one month of use.

3. in addition to formaldehyde of air purifier: There is a filter screen inside the air purifier, which can adsorb formaldehyde in the air and release fresh air when the purifier is running, thus achieving the effect of removing formaldehyde. When in use, the purifier can't purify the air immediately when it is turned on, and it will take some time. Therefore, if you want good indoor air, you'd better open it in advance. Some good purifiers will automatically rest when the indoor air reaches a certain level, so our repeated switching will damage the life of the purifier. Moreover, we should pay attention when turning on the air purifier, and it is best to ensure that the indoor ventilation effect is not obvious, otherwise it will directly affect the purification effect of the machine.
