After the renovation of a new home, one of the most urgent issues people face is the presence of formaldehyde from various building materials. In the past, the common practice was to simply ventilate for about ten days after the renovation. However, even after that short period, it was still unsafe to move in immediately. Many families had to wait months before they could actually live in their newly decorated homes—leaving them scratching their heads and feeling frustrated.
For many, buying a house is the result of years of hard work. It’s not just for the wealthy second generation; for most people, especially in cities like Dalian, where housing prices can reach up to 17,000 yuan per square meter, it's a major financial commitment. Some premium properties, like those with sea views in Xinghai, can cost even more. Even a foreigner earning 7,000 to 8,000 yuan a month would need to save for years just to afford such a home.
A house is more than just a structure—it's the culmination of family effort and emotional investment. Chinese people have a deep connection to their homes, wanting them to be warm, comfortable, and full of love. But the process of renovating often ends up being both financially and emotionally draining. After finishing the renovation, the next challenge is dealing with the lingering odors and potential health risks from formaldehyde.
Everyone knows that many of the materials used in home decoration contain formaldehyde. The stronger the smell after renovation, the worse the pollution. Living in a home with excessive formaldehyde levels can be dangerous and even life-threatening over time.
Formaldehyde is colorless and has a strong, irritating odor. Breathing in low concentrations can cause poisoning, and long-term exposure may lead to serious illnesses like cancer or leukemia. Symptoms of formaldehyde poisoning include coughing, nausea, headaches, dizziness, fever, and skin rashes. These symptoms vary depending on an individual’s sensitivity and overall health.
After a renovation, proper treatment of formaldehyde is essential. Many people rely on ventilation and air fresheners, but these methods are temporary and ineffective in the long run. Once windows are closed, the formaldehyde levels can rise again. Additionally, weather conditions like rain, cold, or smog make ventilation impractical, increasing the risk of poisoning.
Another method people try is using activated carbon to absorb the harmful gases. However, traditional activated carbon has limited adsorption capacity and typically becomes saturated within a week. If not replaced in time, it can release the absorbed formaldehyde back into the air, causing secondary pollution that's even more dangerous.
To address this issue, high-temperature carbonization technology has been developed. This advanced form of activated carbon not only has a much higher adsorption capacity but also has the ability to break down formaldehyde into harmless substances like water and carbon dioxide. This means it can be used safely for up to three years without the risk of re-emission. It’s a more effective and long-term solution for ensuring a safe and healthy living environment after renovation.
