What are the effective methods to remove formaldehyde

The harm of formaldehyde is relatively large, especially when decorating a house. Some materials used are likely to contain formaldehyde. Therefore, it is generally recommended not to move in immediately after the house is decorated. In life, we should also understand some effective methods of removing formaldehyde, such as activated carbon, the use of some plants, and ventilation, which can achieve certain results in removing formaldehyde.

1. Activated carbon adsorption

Activated carbon is a relatively cheap and practical method for removing formaldehyde. It is characterized by physical adsorption, which is thorough and not prone to secondary pollution. The physical effect of activated carbon is deodorization and detoxification; it does not contain any chemical additives and has no effect on the human body.

2. Nanotechnology absorption and decomposition method recommendation index 8.5 The method after decoration is to use products with powerful formaldehyde capture, adsorption and elimination functions. Using high-tech nano and nano modification technologies, after multiple screening, formulation and activation modification, several natural nano-scale raw materials are combined with conventional oxidants to effectively remove harmful gases such as formaldehyde, ammonia, benzene, carbon monoxide, etc. in the living environment. It is not only effective in removing formaldehyde, but also in removing harmful substances such as ammonia, benzene, TOVC, etc. This method can be used if a moderately excessive amount of electricity is placed in an area of ​​30 square meters.

3. Ventilation method to remove formaldehyde

Through the circulation of indoor air, the content of harmful substances in the indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, and the air cannot circulate between indoor and outdoor spaces. Not only will the formaldehyde content in the indoor air increase, but radon gas will also continue to accumulate and even reach a very high concentration.

4. Plant deodorization method

Plant decontamination can be chosen for medium and low pollution: In general, in environments where indoor environmental pollution is light or moderate, and pollution values ​​are below 3 times the national standard, plant purification can achieve relatively good results. Choose and place plants according to the different functions and size of the room. Generally speaking, it is more appropriate to place two pots of plants 1.5 meters high in a room of about 10 square meters. (Recommended indoor pollution control method: ventilation + activated carbon + formaldehyde removal plants, suitable for medium and low pollution)
