Activated carbon is an internationally recognized expert on drug abuse. Activated carbon masks and gas masks are made of activated carbon. The product uses the physical function of activated carbon to deodorize and detoxify; No chemical additives, no influence on human body. Put two or three dishes in each room, and 72 hours can basically eliminate indoor odor. This method can be used for medium and low pollution, and can also be combined with other chemical methods, and the comprehensive treatment effect is better.
2, ventilation method to remove the harm of 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 content of formaldehyde in indoor air will increase, but also radon gas will accumulate continuously, even reaching a very high concentration.

3, soil recruit to remove formaldehyde hazards
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.
4, plant deodorization method to eliminate the harm of formaldehyde.
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.

5, chemical methods to remove the harm of 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.
