I suggest that you choose environmentally friendly materials and furniture when decorating, install them as simply as possible, brush less paint, and control formaldehyde from the root. Window ventilation is indeed the most effective way to remove formaldehyde, but it cannot be completely removed. Prevention is the key to removing formaldehyde. Once it exceeds the standard, serious treatment will be very troublesome and ineffective for a long time. My advice to you is, first of all, to detect pollution sources and remove them. There are paints and latex paints on the surface, and the dispersion is short. It takes more than ten years for inferior plates to release formaldehyde, which has a great influence. In addition to making furniture on site, finished furniture, floors and wooden doors also need attention.
Children and the elderly are not recommended. In fact, even adults can't carry formaldehyde for a long time. It's just that most formaldehyde is produced after opening the window. If formaldehyde can be removed by opening a window, then good materials may have been sealed. After opening the window, the safety factor is high when it is opened for more than 6 months, but the formaldehyde release is slow. First, answer the question directly. There is no point in opening a window, but closing the window is the standard. Because closing doors and windows is a normal rest, the test of closing doors and windows is based on 12 hours.
First of all, why is the national standard closed for inspection 12 hours? Most people are office workers, so they leave work at 6-7 pm and go to work at 6-7 am, ready to leave. During 12 hours, the emission concentration of indoor furniture is the highest. Turn on the heating in winter and the air conditioner in summer. In this 12 hour, people's living environment is relatively closed. How much formaldehyde do they overdose? Through big data monitoring, the country has no long-term harm to people at 0. 10 mg per cubic meter. So the concentration measured by opening the window is very low. Because the air is constantly changing, it is possible to live, but it is not realistic.
