The best way to absorb formaldehyde is onion, which is so effective

There are many ways to absorb formaldehyde in real life, and everyone's approach is different. Studies have found that onions are also effective in absorbing formaldehyde, but it is not enough to rely solely on it. You also need to open windows for ventilation more often, use air purifiers, etc.

Can onions remove formaldehyde?

1. Formaldehyde is a chemical substance and cannot be dealt with by simply using tea leaves or onions. Although indoor ventilation can improve indoor air to a certain extent, we cannot expect it to completely eliminate indoor pollution. If the indoor harmful gases exceed the standard seriously, ventilation will be of no help.

2. 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 and may cause other harm to the human body. The same is true for onions and tea leaves."

3. Place the pot in the corner of the room, the smell will soon disappear, and place more plants. The room should be ventilated for several hours in the morning and evening. In addition, when using formaldehyde remover, be sure to choose an air purifier 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.

What are the methods for removing formaldehyde?

1. Open windows for ventilation: This is really important! Open the windows of the newly renovated house to allow air to circulate, which will reduce the content of harmful substances in the indoor air. For those who are renovating their houses in winter, they should also be careful not to close the windows and doors because they are afraid of the cold. You should know that if the air is not circulated, the formaldehyde content in the city will increase and the radon gas concentration will also increase. Of course, this cannot completely drive away the formaldehyde. The effect is obvious, but after being placed for a period of time, the spider plant that has absorbed too much formaldehyde will turn withered and yellow, and will lose its re-adsorption function. ”

2. The air purifier uses a chemical method. The purifier uses an electric arc to excite negative ions to produce a strong oxidant, bromine oxygen, which oxidizes substances such as formaldehyde in the air and eventually decomposes them into carbon dioxide and water.

After reading the introduction in the above article, now you know whether onions can remove formaldehyde? What are the methods to remove formaldehyde? You should have some understanding of it. Because newly purchased furniture will slowly release formaldehyde, it is better to ventilate frequently for safety, and then use a purifier to let the smell of formaldehyde dissipate as soon as possible and minimize the damage. I hope my introduction can help you.
