For the indoor formaldehyde content, you should know that it cannot be completely removed, as long as the formaldehyde content is less than 0.08mg/m³, It is a safe content range, without excessive pursuit of zero formaldehyde environment. In addition to formaldehyde, you can't listen to advertisements or some folk prescriptions. If you are not careful, you will enter the misunderstanding of formaldehyde removal

myth 1: no taste, no formaldehyde

there is no taste in the room for a short time, which does not mean that the formaldehyde content meets the standard. When the formaldehyde content exceeds the standard by 2-3 times, there is no obvious odor, and it may also be covered up by other odors. Formaldehyde is a kind of gas that is extremely difficult to volatilize and can stay indoors for up to 3-15 years

Myth 2: can ventilation remove formaldehyde

generally, the windows of family rooms are designed to be more than one meter above the ground. The proportion of formaldehyde is larger than that of air, and it is easy to precipitate. Even if the windows are opened for ventilation, it is still difficult to remove formaldehyde. Moreover, most harmful substances are released slowly for 3-15 years, and ventilation cannot solve the problem in a few months

myth 3: is environmental protection decoration free of pollution

using environmentally friendly building materials can help reduce indoor harmful gases, but even if all environmentally friendly building materials are used, the final air quality will exceed the standard. Because most environmental protection building materials only contain harmful substances and emit harmful gases lower than a certain standard, and do not contain harmful substances or emit harmful gases at all. In addition, the design of decoration, room structure, ventilation and other factors, as well as the superposition effect of harmful gases, still can not guarantee that the indoor air quality can meet the standard after the decoration of the room

myth 4: can plants adsorb formaldehyde

many people hope that Chlorophytum comosum, aloe and other plants can absorb formaldehyde. In fact, the respiratory capacity of plants is quite limited, usually at the level of micrograms (one millionth of a gram) of formaldehyde. If the formaldehyde in the room exceeds the standard, thousands of pots of plants need to be placed and continuous light can have a certain effect

myth 5: formaldehyde removal with activated carbon

many people think of using bamboo charcoal and activated carbon to adsorb formaldehyde. At present, there are also many purifiers using the principle of activated carbon, which uses activated carbon to adsorb formaldehyde. How to save money in decoration? On, free design budget quotation. However, this method cannot decompose formaldehyde, and can only be temporarily captured. When the room temperature rises and the adsorption is saturated, formaldehyde will be released again, forming secondary pollution

myth 6: trust scavengers to remove pollution

formaldehyde scavenger covers the surfaces of walls and floors by brushing, smearing, spraying, etc. However, this substance can only slow down the release of formaldehyde and cannot be removed. At the same time, it is a consumable and will become ineffective over time. In addition, formaldehyde scavengers are easy to cause wall discoloration, furniture foaming, wallpaper foaming and other problems, thus damaging the decoration

myth 7: can fumigating vinegar remove formaldehyde

some consumers tried to fumigate vinegar to remove the peculiar smell in home decoration. Experts pointed out that vinegar is an acidic substance, which has a weak role in neutralizing ammonia in the air, but it will not react with formaldehyde and other harmful ingredients. Therefore, this method of removing formaldehyde is not desirable
