Can onion and vinegar remove formaldehyde?

Nowadays, more and more people are buying houses. In many areas, even if you have money, you cannot buy a house, so the housing prices are very high. The first thing to do after buying a house is to decorate it. No matter it is high-end decoration or ordinary decoration, the house needs to be aired for a period of time after the decoration is completed because there will be formaldehyde in it. So the question is, can onion and vinegar remove formaldehyde?

There are many methods for removing formaldehyde on the Internet. Although some methods are relatively old, they are still very effective. The following decoration foreman will recommend the old methods of removing formaldehyde to everyone.

Needless to say, ventilation can effectively remove formaldehyde, but it takes too long. The most effective long-term method is to use green plants. They can convert polluted gases in the air into oxygen needed by humans. Many green plants also have a strong ability to absorb formaldehyde, such as spider plants, tiger tail plants, green radish and ivy, etc., which can reduce the formaldehyde content in the home. However, due to the low adsorption capacity of green plants, it is impossible to effectively remove formaldehyde by relying solely on green plants. You can use activated carbon in combination to utilize its adsorption effect to remove formaldehyde. However, after our activated carbon absorbs formaldehyde, it is possible for it to evaporate again. Moreover, activated carbon is no longer stable when exposed to high temperatures, and its adsorption effect will be greatly reduced.

The last one is formaldehyde removal by photocatalyst. Under the action of ultraviolet light, photocatalyst can effectively degrade toxic and harmful gases in the air; it can effectively kill a variety of bacteria, and can decompose and harmlessly treat toxins released by bacteria or fungi; at the same time, it also has the functions of formaldehyde removal, deodorization, anti-fouling, and air purification.

However, when using photocatalysts, there are some issues that must be paid special attention to. The first is the durability of the effect. Formaldehyde has an extremely long volatilization period, which can be up to fifteen years. Therefore, when choosing formaldehyde removal products, you must pay attention to their effectiveness. Many inferior photocatalysts have a short effective period and will become ineffective or fall off after a short period of time. However, high-quality photocatalysts will electrostatically absorb substances on the surface to form a protective film, which can achieve the effect of long-term pollution elimination.
