After home decoration, many indoor decoration pollutants are generated, which has long become a basic common sense in our daily life. Indoor decoration pollution is very harmful, and it is something that we all understand. Therefore, after the decoration of a new house, we usually leave the house to air for a period of time before moving in, thinking that it will be safer. However, in fact, the effect of removing formaldehyde by natural ventilation is very slow, so other methods are often used in combination. Green plants are considered to be able to remove formaldehyde as they can absorb carbon dioxide, and they are widely used by everyone.

A company in an office building recently completed renovation. In order to remove formaldehyde pollution as soon as possible, they placed a lot of green plants in the room. However, when the workers smiled happily into the newly renovated office, they found that all the various flowers and leaves in the 300-plus square meter office were all withered by the end of the week, not to mention the artistic floral arrangements on the workers’ desks…

In addition, many workers feel that the indoor smell is abnormal, and some workers even have symptoms such as respiratory irritation, shortness of breath, chest tightness, and dizziness. After inspecting the indoor air quality of the company’s office, 3 out of 5 items do not meet the relevant standards, among which formaldehyde exceeds the standard by 8 times!

Many people may find this strange. Isn’t green plants for removing formaldehyde? How could such a situation still occur? Indeed, green plants can take full advantage of absorption and metabolism to dissolve some indoor formaldehyde, but their most important function is to refresh and beautify the home, on this basis, they can help clean up some indoor air pollutants such as formaldehyde. Because of their low efficiency, they cannot be used as the key method for removing formaldehyde.

So how can formaldehyde be removed reasonably?

Method one: Natural ventilation. Although this method is old hat, it cannot be denied that it is indeed effective and can be used in both new and old houses. However, we should try to increase the frequency of natural ventilation rather than always keeping the windows open. Even opening the windows for a while each day is very good. But the uncertain weather limits the time for natural ventilation, which is only a temporary way to reduce the indoor formaldehyde concentration.

Method two: Using raw materials such as activated carbon, which have countless tiny pores, can remove formaldehyde based on the principle of adsorbing organic molecules. The diameter of activated carbon can accommodate harmful substance molecules, removing polar molecules such as formaldehyde and xylene, so that they cannot escape back into the air. However, it should be noted that the service life of activated carbon is relatively short, reaching saturation in 2 to 3 months, so it is necessary to replace new activated carbon regularly.

Method three: Coconut activated carbon. It is an upgraded version of activated carbon, made from coconut shell as raw material, after high-temperature activation and carbonization. It is also a new type of activated carbon containing photocatalytic deodorization and carbon fiber materials. Its adsorption capacity for organic waste gas is 5 times that of general activated carbon, with faster adsorption speed. Compared with general activated carbon, it has stronger adsorption capacity and a longer service life.
