How much formaldehyde is enough to live in

If you have just purchased a new house, you cannot move in immediately, otherwise there will be formaldehyde in your room. You must reduce the formaldehyde content before you can move in, otherwise it will have a great impact on your body. Also, try to plant a lot of plants in your room. These plants will gradually absorb the formaldehyde in the room.

1. The standard is 0.1, and for children it is 0.08. If you want to test, it is best to wait for half a month after the decoration is completed and the furniture and appliances are installed before testing. Because even if your house is decorated to meet the standards and the formaldehyde emitted by the furniture meets the environmental protection standards, the accumulation of several items will cause the formaldehyde in the home to exceed the standard.

The simplest method is to use plants for testing: Chlorophytum. First, close the doors and windows, and place a pot of Chlorophytum at home. After a week, observe the survival status of the Chlorophytum. If its leaves start to turn yellow from the tip to the inside, it means the formaldehyde content exceeds the standard. If the leaves turn yellow from the center or from the roots, it is dead and you don't need to worry about it. First, the leaves turn yellow from the outside to the inside. If it is a slight light yellow, the formaldehyde exceeds the standard by less than 2 times. If it is light yellow on the outside, then gradually turns dark yellow, and then black on the edges, it is 3-5 times. If the leaves turn yellow directly from the outside to the inside, it is serious and is more than 5 times.

1. It is best not to move into a newly renovated house for the time being, because the first year after the renovation, especially the first half of the year, is a period of strong release of harmful gases such as formaldehyde and benzene; 2. When the indoor formaldehyde content exceeds the national standard by less than 1 times, you can use daily forced ventilation and plant flowers and plants with certain formaldehyde removal ability, such as spider plants, to solve the problem. Another good way is to place activated carbon or bamboo charcoal, but these methods act on harmful gases in the indoor air, not on the pollution source, so they are suitable for situations where the content of harmful gases such as formaldehyde is small; 3. When the indoor formaldehyde content exceeds the national standard by more than 1 times, it is necessary to remove formaldehyde from the source. 1) Recommended index for plant absorption: 2. You can grow plants to absorb harmful gases in the air, or use microorganisms and enzymes to carry out biological oxidation and decomposition. This is also a tip for eliminating decoration pollution.
