The newly renovated house is ventilated for 24 hours, and the materials used are better and environmentally friendly. It will take at least 2 to 3 months to move in. If the materials are not good, it will take about 6 months, because there will be a lot of toxic substances such as formaldehyde in the renovated house, which will endanger human health and generally cause respiratory diseases. Normal people can move in as long as 2~3 months, and pregnant women should move in as late as possible. If a baby moves in, it's best to put it in six months.
How to remove formaldehyde from newly renovated houses?
1, activated carbon adsorption.
Activated carbon in addition to formaldehyde is a cheap and practical method, which is characterized by physical adsorption and thorough adsorption, and it is not easy to cause secondary pollution. Physical function of deodorizing and detoxifying activated carbon; No chemical additives, no influence on human body.

2. Nanotechnology absorption and decomposition method.
The method after decoration is to use products with powerful functions of capturing, adsorbing and eliminating formaldehyde. High-tech nano-and nano-modification technologies are adopted, and after multiple screening, formulation and activation modification, several natural nano-raw materials are combined with conventional oxidants, which can effectively remove harmful gases such as formaldehyde, ammonia, benzene and carbon monoxide in the living environment. Not only for formaldehyde, but also for ammonia, benzene, TOVC and other harmful substances. This method can be used to put a moderately over-standard in 30 square meters.
3, ventilation method to remove formaldehyde.
Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thus reducing the harm of such substances to human body. People often close doors and windows in winter, so the indoor and outdoor air can't circulate. Not only the formaldehyde content in indoor air will increase, but also radon will accumulate continuously, even reaching a very high concentration.
4, soil tricks. 300 grams of black tea is soaked in two basins of hot tea, put it indoors, and open the window for ventilation. Within 48 hours, the indoor formaldehyde content decreased by more than 90%, and the pungent smell was basically eliminated.
5. Plant deodorization method.
Plant decontamination can be selected for medium and low pollution: generally, indoor environmental pollution is light and moderate, and the pollution value is less than 3 times of the national standard. Using plants to decontaminate can achieve better results. Choose and place plants according to different functions and areas of the room. Generally speaking, it is more appropriate to put two pots of plants with a height of 10 square meter in a room with a height of10 meter.

6, chemical method to remove formaldehyde.
Spray and other drugs are easy to cause secondary pollution, which may damage furniture, while activated carbon is physically adsorbed, which is safe and harmless to human body and has anti-mildew and anti-corrosion effects on furniture. Advocate one-time removal (experts doubt it, which is not credible), and the release of toxic gases at home is a slow process, so it will be removed today, and it will smell again in a few days, and the price is not low. The products are too miscellaneous to distinguish clearly. Although many products that control formaldehyde are under the banner of "high technology" and "environmental protection", some inferior chemical synthetic substances are used. Although these products can eliminate formaldehyde to a certain extent, they may also produce other pollutants again, leading to secondary pollution. Therefore, consumers must be vigilant when purchasing formaldehyde control products. For example, chemical air treatment products are obtained by artificial synthesis, many of which are aromatic compounds. Almost all aromatic compounds contain benzene ring compounds that have been proved or suspected to be carcinogens. In addition, many chemical products are oxidizing and corrosive, which are easy to damage utensils, as well as operators and residents. When the coating is aging and the weather is hot and humid, the coating is easily damaged, releasing harmful substances such as formaldehyde, which becomes a hidden "time bomb" in the family.
7, pure Chinese herbal medicine spray decomposition method.
This is a better, more effective and promising removal method. It combines the advantages of plant removal and chemical removal, and abandons their disadvantages. First of all, it is safer than chemical in addition to formaldehyde and there is no secondary pollution. Compared with the plant removal method, the effect is better because it is a herbal extract. With the improvement of people's living standards and the strengthening of environmental protection concept, this pure herbal method of removing decoration pollution will be more and more popular.
