How to remove formaldehyde after renovation
After the renovation of a new house, formaldehyde pollution is one of the biggest concerns for many families. Formaldehyde is a harmful gas and long-term exposure may cause serious health effects. In order to help everyone effectively remove formaldehyde, this article will combine the hot topics and hot content on the Internet in the past 10 days to provide scientific and practical methods for removing formaldehyde.
1. The hazards and sources of formaldehyde
Formaldehyde is a colorless gas with a pungent odor, mainly derived from adhesives, paints, boards, etc. in decoration materials. Long-term exposure to formaldehyde may cause respiratory diseases, skin allergies, and even increase the risk of cancer. Therefore, it is very important to remove formaldehyde in time after decoration.
| Formaldehyde sources | degree of harm |
|---|---|
| Artificial panels (such as density board, plywood) | high |
| Paints and coatings | in |
| wallpaper, carpet | low |
2. Effective methods for removing formaldehyde
The following are several scientific formaldehyde removal methods that are hotly discussed on the Internet for your reference:
| method | Principle | Effect |
|---|---|---|
| ventilation method | Dilution of formaldehyde concentration by air movement | Significant short-term effects |
| Activated carbon adsorption | Using porous structure to adsorb formaldehyde | Need to be replaced regularly |
| photocatalytic decomposition | Catalytic decomposition of formaldehyde by light | Effective for a long time |
| Phytopurification | Some plants can absorb formaldehyde | auxiliary effect |
3. Specific operational suggestions
1.ventilation method: Ventilate for at least 3-6 months after decoration. Especially when the temperature is high in summer, formaldehyde is released faster and the ventilation effect is better.
2.Activated carbon adsorption: Place activated carbon in closed spaces such as closets and drawers, and replace it once a month to avoid secondary pollution.
3.photocatalytic decomposition: A professional company can be hired for construction and spraying of photocatalyst materials, which must be used in conjunction with ultraviolet lamps.
4.Phytopurification: Plants such as pothos, spider plant, and sansevieria are recommended. Although the effect is limited, they can improve the indoor environment.
4. Common misunderstandings
1.Grapefruit peel and tea leaves remove formaldehyde: These methods can only mask the smell and cannot really remove formaldehyde.
2.Simply rely on air purifiers: The air purifier has limited adsorption capacity for formaldehyde and needs to be used in conjunction with other methods.
3.Anxious to move in: Even if the formaldehyde removal method is used, it is recommended to pass the test before moving in.
5. Formaldehyde testing recommendations
After renovation, it is recommended to use a professional formaldehyde detector or hire a testing agency to ensure that the indoor formaldehyde concentration is lower than 0.08mg/m³ (national standard). The following is a comparison of common detection methods:
| Detection method | Advantages | Disadvantages |
|---|---|---|
| Professional testing agency | Data is accurate | higher cost |
| Home detector | Convenient and fast | Accuracy varies |
| Formaldehyde test paper | low cost | Rough results |
6. Summary
Formaldehyde removal is a systematic project that requires a combination of multiple methods. Ventilation is the most basic method, activated carbon and photocatalyst can be used as assistants, and plant purification can beautify the environment. Avoid misunderstandings and conduct scientific testing to ensure the health of your family. I hope this article can help you feel comfortable moving into your new home!
