Formaldehyde is a common harmful substance in renovations, typically originating from materials such as boards, paint, and flooring. In newly renovated homes, formaldehyde levels are often high, posing potential health risks. If not dealt with promptly, prolonged exposure to formaldehyde can lead to respiratory diseases, allergic reactions, and even cancer. Therefore, addressing formaldehyde pollution after renovation is critical. So, how should we effectively resolve severe formaldehyde issues after renovation?
1. Open Windows and Ensure Ventilation
The most direct and effective method is ventilation. Formaldehyde usually requires time to evaporate, so prolonged ventilation can effectively expel formaldehyde from the indoor air. It’s recommended to keep windows open for 2 to 3 hours a day, especially during good weather, ensuring air circulation.
2. Use Air Purifiers
Air purifiers, particularly those equipped with formaldehyde removal features, can help refresh indoor air and remove harmful substances. When choosing an air purifier, opt for one that features HEPA filters and activated carbon filters for more effective absorption and removal of formaldehyde.
3. Activated Carbon Absorption
Activated carbon is widely used for its strong adsorption ability to remove formaldehyde. Place activated carbon bags in various corners of the home, especially in enclosed spaces like cabinets, wardrobes, and under the bed. Additionally, there are specialized formaldehyde-absorbing products available on the market, which can quickly absorb harmful gases in the air.
4. Plant Absorption
Certain plants, such as spider plants, aloe vera, and snake plants, have natural air-purifying functions and can absorb harmful substances like formaldehyde. These plants not only improve indoor air quality but also beautify the home environment. Although the effects of plants are relatively slow, they are a great supplementary method.
5. High Temperature to Accelerate Formaldehyde Evaporation
Raising the indoor temperature using heaters or air conditioning can speed up formaldehyde evaporation. However, this method should be used with caution, particularly in homes with pets or young children, as high temperatures can introduce other potential risks.
6. Chemical Formaldehyde Removers
There are chemical formaldehyde removal products on the market that work by breaking down formaldehyde molecules to reduce concentrations. When using these products, be sure to follow the instructions carefully and ensure good ventilation afterward to avoid introducing new air pollution.
7. Natural Decomposition Over Time
Formaldehyde naturally decomposes over time. Typically, formaldehyde levels decrease gradually within six months to a year after renovation. Therefore, maintaining long-term ventilation and air circulation, as well as periodically testing the indoor formaldehyde concentration, is a natural method to address the problem.
8. Formaldehyde Detection and Treatment
If formaldehyde contamination is severe, consider professional formaldehyde testing. Some companies offer formaldehyde treatment services, using specialized equipment and techniques to remove formaldehyde from indoor spaces. If formaldehyde levels exceed safety limits, hiring a professional is recommended.
9. Replace Contaminated Sources
If formaldehyde pollution is serious and other methods are ineffective, consider replacing certain decoration materials that contain formaldehyde. For example, replace high-formaldehyde boards or paints to reduce pollution at the source.
The issue of formaldehyde pollution after renovation should not be overlooked. However, through proper ventilation, air purifiers, and natural methods such as plants, we can effectively reduce formaldehyde levels and improve indoor air quality. To ensure a safe living environment, it’s important to choose low-formaldehyde or formaldehyde-free materials before renovation and implement formaldehyde treatment measures to guarantee a healthier home environment.
