When the weather gets cold and the temperature drops, will formaldehyde be released indoors?

As long as the indoor temperature is higher than 19℃, formaldehyde will volatilize, but it will volatilize slowly at the bottom of the temperature and quickly above 25℃. This is also related to the indoor pollution level. If the pollution is serious, release it quickly.

The release period of formaldehyde is 3 to 15 years, which needs to be used with ventilation and some articles that absorb formaldehyde after reaching the standard.

Indoor formaldehyde mostly comes from various artificial boards (large core board, nine-mile board, medium density board, etc.). ). Coatings and paints also contain some formaldehyde, but the content is low.
