The test formaldehyde need to close the window, the test data is valuable, ventilation can quickly reduce the value of formaldehyde content in the room. Because it is not possible to open the window 24 hours a day, or 24 hours a day to blow away the formaldehyde out of the home. You can't open the window when it rains, and it's not good for your body to open the window at night if you sleep in the wind. So it is recommended not to move in. Open all the cabinets in the house, it does not rain, open the window, can help distribute formaldehyde. After a while, it is best to re-test in a closed state. It is best to test the room for a few more points. It is safe to wait until all standards are met before moving in. The choice of test points is very important. There is a lot of furniture, so choose a painted area to test. Every sleeping room should be tested. The purpose of the test is to confirm that the standards are not being exceeded.

I recommend that you choose environmentally friendly materials and furniture when decorating, installing as simply as possible, and applying less paint in order to manage formaldehyde in excess from the root. Window ventilation is indeed the most effective way to remove formaldehyde, but you can't rely entirely on window ventilation to remove formaldehyde. Removing formaldehyde is focused on prevention, and once the standard is exceeded, serious management is very troublesome and ineffective in the long run. The advice to you is, first of all, to detect the source of pollution, remove the source of pollution. Paint, latex paint exists on the surface, the dispersion is short. Inferior board internal formaldehyde release takes more than ten years, the impact is great. In addition to making furniture on site, finished furniture, flooring and wooden doors also need attention.

Having children and the elderly is not recommended to move in. In fact, even adults can not carry formaldehyde for a long time. Only most of the formaldehyde produced after opening the window, if opening the window can remove formaldehyde, then the good materials may have been closed. After opening the window, open more than 6 months to move in, the safety factor is high, but formaldehyde release to slow. First of all, to answer the question directly on the subject of the question, it makes no sense to open the windows, and it is standard to close them. Because closing the windows and doors is a normal rest, so close the windows and doors test to 12 hours shall prevail.

First of all, to say why the national standard closed 12 hours of inspection. Most of the average person is a working person, so 6 ~ 7 p.m. in the afternoon off work, 6 ~ 7 a.m. to work, ready to go. During these 12 hours, the highest concentration of furniture emissions into the room. Winter to open the heating, summer to open the air conditioning, this 12 hours people live in a relatively sealed environment, specifically breathing how much formaldehyde overdose? National monitoring through big data, 0.10 milligrams per cubic meter, there is no long-term harm to people. Therefore, the concentration measured with the windows open is very low. Because it is a constant replacement of air, it is possible to live, but not realistic.
