Can onions remove formaldehyde? How to fight against formaldehyde

Colorless and odorless formaldehyde is indeed a pollutant hidden around us that is not easy to be found. According to national standards: when a home is closed for 1 hour, the liquid concentration of free formaldehyde in the air must be less than or equal to 0.08 ml/cubic meter. There are many "air formaldehyde self-test kits" on the market. Such a box costs only a dozen yuan and can detect the formaldehyde concentration in the room.

Many families like to use wallpaper when decorating their homes. Wallpaper itself does not contain formaldehyde, but the glue used to paste wallpaper contains a lot of formaldehyde. Many people like to lay wooden floors in their bedrooms. However, wooden floors are not pure solid wood, and glue containing formaldehyde is used during the pressing process.

After talking about the furniture and floors in the house, let’s turn our attention to the car. After buying a new car, there will be a strong smell inside the car, especially for lower-priced cars. The use of inferior materials causes serious exceeding of the standard of formaldehyde, benzene and other pollutants inside the car. Ms. Gao, a citizen, reported that she had bought the car for more than half a year, but there has always been a pungent smell that cannot be removed. Ms. Gao suspected that the car might contain excessive amounts of harmful substances such as formaldehyde and benzene, so she should ventilate the car more often and place bamboo charcoal bags in the car.

Many car owners are accustomed to putting a bamboo charcoal bag in their cars, but if the bamboo charcoal bag is not used correctly, it will not be able to remove formaldehyde. After a few days of use, the bamboo charcoal should be taken out of the car and exposed to the sun before being put back into the car for use. If it is always left in the car exposed to the sun, it will be counterproductive. For families who have the means, it is recommended to use herbal Dialin to spray to remove formaldehyde in the car, which will be more effective. In order to cover up the pungent smell in the car, some car owners choose to use perfume, because benzene has a aromatic smell, if perfume is placed again, it will aggravate the pollution in the car. In summer, ventilate the car before getting in, which not only cools it down but also removes odors. If you are still worried, remove the formaldehyde from the entire car to make your driving more secure.
