When we excitedly prepare to move into a new home or renovate an old space, we often notice a faint, sharp smell indoors. Most people simply open the windows for ventilation, do some cleaning, and spray air deodorizer, thinking the problem is solved. However, a toxic gas called formaldehyde has already seeped deeply into our living environment without us realizing it.
We've all heard of formaldehyde, but how many of us truly understand what it is and where it comes from?
Formaldehyde is a type of volatile organic compound (VOC), and its primary sources include interior decor, building materials, furniture, and household items. During the manufacturing process, chemical substances like preservatives and adhesives are often used, with formaldehyde being a colorless and highly volatile toxic gas. It can silently pose serious health risks without us even noticing.
However, because formaldehyde is colorless and volatile, it’s hard to tell if it’s truly been eliminated. Where does it linger, or how does it generate new toxic gases? It’s not just large projects like renovations or furniture that leave behind formaldehyde; even new carpets, sofas, and children's toys can contain it. Once you understand where formaldehyde comes from, it’s easier to take the right steps to remove it.
