In-depth understanding of formaldehyde: the source and three states of indoor formaldehyde

Formaldehyde, as a colorless irritating gas, is widely present in our living environment. Although it also has a natural source in nature, indoor formaldehyde is mainly associated with man-made materials and products. Understanding the source and state of formaldehyde is essential to prevent and reduce its health effects.

The main source of indoor formaldehyde

Indoor formaldehyde is a colorless irritating gas, and its main sources can be divided into the following categories:

Household items: Many household items, such as curtains, carpets, sofas, and other textiles, may have used formaldehyde-containing dyes or finishes in the production process.

Decoration materials: In the interior decoration process, the paints, coatings, wallpapers, flooring and other materials used may contain formaldehyde, which will release formaldehyde during the drying and curing process.

Furniture adhesives: Adhesives used in furniture manufacturing, especially urea-formaldehyde and phenolic resins, are one of the main sources of formaldehyde. These adhesives continuously release formaldehyde during the making and use of furniture.

There are three states of formaldehyde in the room

Indoor formaldehyde can be divided into the following three states according to the degree of its combination with the material:

Bound formaldehyde: Formaldehyde in this state is bound to other components in the material and is usually found inside furniture and decoration materials. Over time, this formaldehyde is gradually released into the indoor air.

Free formaldehyde: Free formaldehyde refers to formaldehyde that has been released from the material and is present in the indoor air. Formaldehyde in this state has the most direct impact on the human body.

Adsorbed formaldehyde: Adsorbed formaldehyde refers to formaldehyde that is adsorbed by other indoor substances, such as walls and furniture surfaces. Under certain conditions, this formaldehyde may be released back into the air.

How to effectively remove formaldehyde

In order to reduce the concentration of formaldehyde indoors and protect the health of occupants, the following measures can be taken:

Control formaldehyde at the source: When buying furniture and renovation materials, choose products that are labeled "low formaldehyde" or "formaldehyde-free" to reduce the initial release of formaldehyde.

Strengthen ventilation: Regularly open windows for ventilation, especially after renovation and when new furniture is moved in, can effectively reduce indoor formaldehyde concentration.

Professional treatment: For serious formaldehyde pollution, you can ask a professional indoor air treatment company to carry out formaldehyde treatment.

The in-depth understanding of indoor formaldehyde not only includes understanding its source and existence state, but more importantly, mastering effective removal methods. By taking these steps, we can significantly reduce indoor formaldehyde concentrations and create a healthier and safer living environment for ourselves and our families.
