1. Activated carbon adsorption method recommended index: 7
Activated carbon in addition to formaldehyde is a relatively cheap and practical method, characterized by physical adsorption, thorough adsorption, and is not likely to cause secondary pollution. The physical function of activated carbon deodorizes and detoxifies; without any chemical additives, it has no effect on the human body. Two or three dishes per room, 72 hours can basically eliminate the indoor odor. This method can be used for medium and low-level pollution, and it can also be used in combination with other chemical methods. The comprehensive treatment effect is better.
2. Nanotechnology absorption decomposition method recommendation index 8.5
The decoration method is to use a product that has a powerful function of capturing, adsorbing, and eliminating formaldehyde. Utilizing high-tech nano- and nano-modification technology, through multiple screening, compounding and activation modification, combining several natural nano-scale raw materials with conventional oxidants can effectively remove harmful gases such as formaldehyde, ammonia, benzene, and carbon monoxide in the indoor environment. . It is not only effective against formaldehyde but also effective in removing harmful substances such as ammonia, benzene and TOVC. 30 square meters to put a moderate degree of excess can use this method.
3. Ventilation method to remove formaldehyde Recommended index: 6
Through the circulation of indoor air, the content of harmful substances in the indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, indoor and outdoor air can not circulate, not only the content of formaldehyde in indoor air will increase, helium will continue to accumulate, and even reach a high concentration. . (Recommendation: Ventilation ***)
4. Tujia recommendation index: 7
300 grams of hot tea with tea and two basins of water are put into the room, and the ventilation of the windows is opened. The formaldehyde content in the room will decrease by more than 90% within 48 hours, and the pungent odor will be basically eliminated. (Recommendation: ***)
5. Plant deodorization method recommendation index: 7.5
Medium and low-level pollution can be decontaminated by plants: In general, the indoor environment is polluted with mild and moderate pollution, and the pollution value is less than 3 times the national standard. The use of plant purification can achieve better results. According to the different functions of the room, the size of the area is selected and placed on the plant.
Under normal circumstances, about 10 square meters of room, 1.5 meters high plants put two pots more appropriate. (Recommended indoor pollution control methods: Ventilation + activated carbon + addition of formaldehyde plants, suitable for low-to-medium pollution) Choose and place plants according to the different functions of the room, the size of the area. Under normal circumstances, about 10 square meters of room, 1.5 meters high plants put two pots more appropriate. (Recommendation: Chlorophytum, Tiger Piran ****)
6. Chemical removal of formaldehyde Recommended Index: 6
(1). Spraying and other drug treatment can easily cause secondary pollution and may damage furniture. Activated carbon is physically adsorbed. It is safe and harmless to the human body. It has anti-mildew and anti-corrosion effects at home.
(2). Advocate a one-time removal (expert questioning, not credible), and the release of poison gas at home is a slow process, so today it is removed, there are tastes in a few days, and the price is not low.
(3). The products are too complicated to distinguish. Many of the products that deal with formaldehyde, despite the banner of "high-tech" and "environmental protection," use some inferior chemical synthetic substances. Although these products can eliminate formaldehyde to a certain extent, it is also possible to re-manufacture other pollutants and cause secondary pollution.
7. Pure Herbal Spray Decomposition Method Recommended Index: 10
This is a removal method that is currently relatively good, effective, and has a bright future. It combines the advantages of plant removal and chemical removal to abandon their deficiencies. First, it is safer from secondary pollution than chemical removal of formaldehyde. , compared with the plant removal method, because it is an herbal extract, so the effect is better. With the improvement of people's living standards and the strengthening of the concept of the environment, such a purely herbal approach to remove decoration pollution will become more and more popular.
