There is a formaldehyde odor after interior decoration, can you remove formaldehyde with onions

1. Can onions remove formaldehyde?

Formaldehyde is a chemical and cannot be dealt with simply by using natural plants - tea, onions, etc. Indoor ventilation, although it has a certain effect on improving indoor air, can not be expected to completely remove indoor pollution, indoor harmful gases exceed the standard, ventilation is useless.

The principle of onion, orange peel, and grapefruit peel, which is often used to remove the smell of decoration, is that its molecule is larger than the formaldehyde molecule, so it can "cover" the smell but is not really adsorption. Pineapple only reduces the smell of formaldehyde, formaldehyde is still volatile, "pineapple in addition to the smell of formaldehyde at the same time, will also have some reaction with formaldehyde, may cause other harm to the human body, onion and tea is the same."

I don't know when the method of "onion to remove formaldehyde" came out, and some people think that onions can be "sterilized", so they can "kill formaldehyde". In response to this problem, experts were consulted, and the statement about the removal of formaldehyde from onions is simply nonsense. Formaldehyde is a chemical product, and onions do not have the ability to break down formaldehyde.

The reason why the onion no longer smells of formaldehyde when placed indoors is because the smell of the onion covers the formaldehyde. Covering up the odor does not mean that formaldehyde is eliminated, and this practice of avoiding the heavy and lightening it has no effect on the treatment of formaldehyde at all.
