The smell of new home decoration, the "unique" odor emitted by furniture, and even the fragrance of cleaning agents These may all hide an 'invisible disruptor' - VOCs! Who exactly is it? How harmful is it? What is the relationship with formaldehyde? Explain it clearly!

Unveiling the Veil: VOCs: The Ubiquitous' Gas Evacuation '

Formaldehyde is undoubtedly the number one "star" of indoor air pollution, with high visibility and great harm. However, there are many other equally or even more harmful members in the large family of indoor volatile organic compounds (VOCs), which together constitute the "invisible killer" of our breath. Ignoring them is equivalent to leaving a huge safety loophole in indoor air quality issues.

We cannot just focus on formaldehyde, but must pay attention to 'other volatile harmful gases'

【 Key clarification 】 Formaldehyde ≠ VOCs! It's just a 'celebrity student'

VOCs are a large family of harmful substances, so in our decoration process, we cannot just focus on "celebrity students"

TVOC: This refers to "total volatile organic compounds", representing the total amount of volatile organic compounds in indoor air. Formaldehyde is just one of them (although it is usually an important one). Excessive TVOC can also have a significant impact on human health.

Excessive levels of benzene, toluene, and xylene can also have a significant impact on human health.

Special Reminder! These groups of people are more susceptible to the "surprise attack" of VOCs and need double protection:

Child: The body defense system is still under construction and is fragile and vulnerable.

Expectant mother: During special periods, the body is more sensitive and requires comprehensive protection.

Elderly people: Their physical function and resistance are not as strong as before, and they are the key protected objects.

Physically weak: People with poor resistance should also be vigilant.
