Method one. Removal of formaldehyde by activated carbon adsorption.

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. There is also an active ore which has the same function as activated carbon.

Method two, 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.

Method 3: Eliminate the harm of formaldehyde with indigenous methods.

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.

Method four. 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, so plant decontamination can achieve good 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.
