Where does the decoration pollution mainly come from?

According to statistics, 90% of newly renovated houses have exceeded the standard of formaldehyde or benzene gaseous pollutants. How to remove formaldehyde and benzene from the new house and how to eliminate them quickly has become a very important task before moving into the new house. Formaldehyde and benzene have a stubborn characteristic, and the following methods are recommended.

1. Window ventilation is a very simple method to remove formaldehyde. The principle of purification is indoor and outdoor air circulation replacement, which releases harmful gases such as free formaldehyde in indoor air to the outside and reduces indoor formaldehyde concentration. Its aldehyde removal efficiency is directly related to outdoor wind power. Generally, the greater the outdoor wind, the higher the purification efficiency.

2. Using green plants to purify formaldehyde is a popular and promising in addition to formaldehyde method. Plants will absorb a part of formaldehyde during photosynthesis, but the absorption amount is very small, so it is suggested to use it as an auxiliary method in in addition to formaldehyde.

3. There are a lot of irregular pores in activated carbon, among which pores similar to formaldehyde molecules will adsorb formaldehyde, which can achieve the purpose of purifying the air. However, the number of pores in activated carbon is limited, which may cause secondary pollution when saturated, so it must be replaced regularly when used.

5. The fresh air system can ensure 24-hour ventilation in the home, which can greatly increase the exchange of indoor air with the outside world. Although the effect is very good, this fresh air system is expensive, and it is a better choice to install it before decoration.

6. At high temperature, it can promote the conversion of bound formaldehyde into free formaldehyde and reduce the total formaldehyde content, because formaldehyde can not be completely removed, but the effect is still obvious?
