Can onions remove formaldehyde?

With the development of the economy, urban pollution has become more and more serious. People are trying every possible way to get rid of all kinds of odors. This is not only good for children, but also for the family. Of course, we all know that plants can purify the air because they can release oxygen and consume carbon dioxide. Therefore, greening in cities is extremely necessary. So, besides plants, what else has a greening effect?

Some people say that onions can remove formaldehyde. In my opinion, this is not the case. After all, onions have a strong smell, so it is possible that the smell of onions masks the smell of formaldehyde. Just like grapefruit peel, it is actually not very effective in removing formaldehyde.

Onions, orange peels, and grapefruit peels are often used to remove decoration odors. The principle is that their molecules are larger than formaldehyde molecules, so they can "cover" the odor but are not true adsorption. Pineapple only reduces the smell of formaldehyde, while formaldehyde is still volatilizing. "While pineapple removes the smell of formaldehyde, it will also react with formaldehyde, which may cause other harm to the human body. The same is true for onions and tea leaves."

Place the pot in a corner of the room, the smell will soon disappear, and add more plants. The room should be ventilated for several hours in the morning and evening. In addition, when using formaldehyde removers, be sure to choose air purifiers that will not cause secondary pollution. For example, the effect of Queganling is quite good. It can not only quickly remove harmful gases such as formaldehyde, but also quickly remove odors.

Therefore, if we want to get rid of the odor or formaldehyde in the room as soon as possible, it is better to open the window to allow the air in the room to circulate sufficiently. Of course, the purification effect of plants is still very large. It is also a good idea to put a few more potted plants. At the same time, we can also use some chemical products, such as air fresheners to remove odors.
