I suspect it's the smell of benzene, because benzene is fragrant, commonly known as aromatic killer. Formaldehyde is a pungent smell. A person's nose can only smell the smell of pollution exceeding the standard by more than 4 times, while the smell of pollution exceeding the standard by less than 4 times is invisible to the nose. At present, there is no simple method to remove harmful decorative pollution such as formaldehyde and benzene, and usually several methods are used together to get the effect. The volatilization period of formaldehyde is about 3- 15 years, and that of benzene and benzene series is about 3 years.

Newly renovated rooms and newly bought furniture are polluted, which are generally solved by the following methods. 1, keep good ventilation at all times to strengthen volatilization. 2. Put more flowers and plants (aloe, chlorophytum, ivy, cactus, etc. ) and activated carbon (including furniture) absorb toxic gases indoors. 3. If conditions permit, it is recommended to go to indoor air testing and ask professionals to handle it. If the above methods are adopted, the effect will be better! ! ! For the sake of the next generation, pregnant women and babies had better not live in such rooms. If they must live, it is recommended to use the above three methods, especially the third one, so as to be safe. As for putting vinegar, pineapple, perfume, onion or any other air freshener, it is a big mistake, because it only covers up and mixes the pollution sources, not cleans them up, so the pollution will actually be more dangerous, and people will unconsciously absorb various harmful compounds, which will do great harm to the human body.
