The weather is hot and the house has just been renovated. Will formaldehyde be released by itself?

The natural release of formaldehyde is a slow process.

Ventilation method

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 will the formaldehyde content in the indoor air increase, but radon gas will continue to accumulate and even reach a very high concentration.

Advantages: good effect and no cost.

Disadvantages: It takes a long time, and formaldehyde removal generally takes more than three years.

Deodorization method

Formaldehyde deodorant Chinese characters capture and decompose harmful pollutants of formaldehyde, benzene and purple ammonia, kill harmful microorganisms of germs and mites, purify the air and eliminate peculiar smell.

Soak in water, vinegar and black tea to remove formaldehyde.

Many people on Amethyst say that because formaldehyde is soluble in water, you can put more pots at home to absorb formaldehyde or soak it in vinegar or black tea. It is a fact that formaldehyde is easily soluble in water, alcohol and ether.

Free formaldehyde in the air will dissolve in water during exercise, which is similar to the adsorption principle of activated carbon. The contact area between a basin of water and air is only the size of a basin, while the specific surface area of internal pores of 1g activated carbon can reach the size of a football field. Even if you put a hundred pots of water in the room, the adsorption effect will not be much stronger than a small bag of activated carbon.

Therefore, it is obviously unrealistic to use water, black tea and vinegar to adsorb formaldehyde. The release of formaldehyde is closely related to indoor temperature and humidity. With the increase of temperature, the release of formaldehyde will greatly increase. The experimental results show that when the relative humidity in the air increases 10%, the indoor formaldehyde emission will increase by about 5%.
