Is there no formaldehyde in the new house in winter? Is there formaldehyde in the new house in winter?

1, no, there is formaldehyde in winter.

2. The release period of formaldehyde is as long as 3- 15 years, which is not limited by seasons, but the release amount will change according to indoor temperature and humidity. In high temperature and high humidity environment, formaldehyde emission will increase, which will lead to the increase of indoor formaldehyde concentration. For example, in winter, although the weather is relatively cold, many families often close doors and windows and use heating equipment to keep warm, which leads to an increase in indoor temperature and formaldehyde emission.

3. In this case, more formaldehyde will be released in winter, especially in the north and south. In winter, the north provides heating and the indoor temperature is high, while many places in the south do not provide heating and the temperature is low. Therefore, when winter comes, the newly renovated houses in the north have the highest formaldehyde emission, and the south is relatively better.
