With the rapid pace of urbanization and rising living standards, indoor environments have significantly improved. However, excessive decoration has led to increased indoor air pollution, which remains a major threat to human health. It is now more critical than ever to address this issue through stronger regulations and effective measures.
Formaldehyde levels in some homes are over six times higher than safe limits, while mosquitoes and other pests are being repelled by the fumes. This alarming situation was highlighted when Mr. Zhang, who recently moved into a newly renovated luxury apartment in Longcheng, found that even flies were being smoked out of his home. Testing by the Qingxiu District Quality Supervision Station revealed that formaldehyde levels were six times above the national standard.
Similarly, Ms. Zeng's family experienced severe health issues after moving into their new home. Symptoms included dizziness, memory loss, irritability, and sore throats. After hospital visits, they were advised to test their home’s air quality. The results from the Qingxiu District Quality Supervision Station were shocking: formaldehyde, benzene, and TVOC levels were all severely exceeded, with four key pollutants monitored, including radioactivity.
Data shows that such pollution can cause serious harm, including potential links to leukemia. Inferior building materials are often the root cause. A study involving over 330 new homes found that formaldehyde, benzene, ammonia, and radioactive materials were the main sources of indoor pollution. These toxins come from wood panels, furniture, paints, adhesives, wallpapers, and carpets—common materials used in modern renovations.
Environmental pollution can lead to brain hypoxia, nerve damage, dizziness, nausea, and even death in extreme cases. Formaldehyde and benzene are especially dangerous as "invisible killers" in the air. They can cause chronic poisoning, affect the blood system, respiratory tract, nervous system, and immune system, and may even lead to mutations or birth defects.
To tackle this growing problem, experts suggest closing the supply chain for substandard materials, regulating the decoration market, and conducting strict indoor environmental monitoring. Research into biological pollution control methods should also be prioritized to cut off the source of indoor pollution.
As winter brings an increase in home renovation activity, specialists advise the public to take proactive steps. Using photocatalysts and other air purification methods can help improve indoor air quality. When signing renovation contracts, it's wise to include an air quality clause to protect your rights if problems arise. Before moving in, request a professional indoor air test to ensure that pollution levels are below national safety standards.
Only then can you truly feel at ease in your new home.
Aluminum single hung window is a relatively new type of window. Here is a detailed introduction about it:

It does not occupy the horizontal space indoors or outdoors and is particularly suitable for installation in locations with limited space, such as kitchens, bathrooms, narrow corridors, etc.
Advantages:
Good ventilation:Aluminum single hung windows can be opened to a large extent, so that indoor and outdoor air can circulate fully, effectively improving the indoor ventilation effect. In addition, some aluminum single hung windows can also realize multi-sash linkage to further increase the ventilation area.
Wide field of vision: Due to the particularity of its opening method, aluminum single hung windows will not be blocked by window frames like casement windows when opened, which can provide a wider field of vision and make the indoor space more transparent and bright.
High safety: When the window sash is closed, it fits tightly with the window frame, and with high-quality sealing strips, it can effectively prevent rain, dust, wind and sand from entering the room. At the same time, some aluminum single hung windows are also equipped with safety locks and other devices to enhance the anti-theft performance of the windows.
Easy to clean: The window sash can be tilted inward or outward, which is convenient for users to clean the inside and outside of the window, solving the problem of difficult cleaning of high-rise windows.
