How to remove formaldehyde from new sofa
We all know that formaldehyde is particularly harmful, so we will remove formaldehyde from all aspects. We usually don't think that there is formaldehyde in the sofa at home. So we can remove formaldehyde by some small methods. Wood-based panels in in addition to formaldehyde, due to the use of adhesives in the manufacturing process of wood-based panels, it is necessary to carry out formaldehyde treatment on the wood-based panels under the sofa, so that they can be moved out for airing and ventilation. This in addition to formaldehyde method is very good.
The main reason why formaldehyde exists in the new sofa is that it is adsorbed on the surface of the material. Because the main material of sofa cover is cloth, it is easy to absorb volatile formaldehyde. Because formaldehyde is water-soluble, we need to clean sofa cover regularly, and then dry it for ventilation, which can effectively reduce the formaldehyde content. This method is very effective in removing formaldehyde.
I bought it by mistake. This sofa is made of formaldehyde. The skeleton of the sofa is made of wood-based panels, which contain formaldehyde, so the sofa also contains formaldehyde. We can buy fresh onions, cut them a few times, put them in a small dish, and put half a dish of water around the fabric sofa. It should be improved in a week or so!

What absorbs formaldehyde?
The things that absorb formaldehyde are chlorophytum, aloe and other plants and activated carbon. The main methods of absorbing formaldehyde are: plant elimination method and adsorption method.
Adsorption method (activated carbon)
Adsorption is a solid surface phenomenon. It uses porous solid adsorbent to treat gaseous pollutants, so that one or more components are adsorbed on the solid surface under the action of molecular attraction or chemical bond force on the surface of the solid adsorbent, thus achieving the purpose of separation.
Commonly used solid adsorbents are coke and activated carbon, of which activated carbon is the most widely used. Activated carbon can adsorb benzene, toluene, xylene, ethanol, ether, kerosene, gasoline, styrene, vinyl chloride and other substances.
Plant exclusion method (chlorophytum, aloe)
Chlorophytum, Aloe Vera and Eupatorium adenophorum can absorb a lot of indoor formaldehyde and other pollutants to eliminate and prevent indoor air pollution. Germicides secreted by flowers such as jasmine, clove, honeysuckle and morning glory can kill some bacteria in the air, inhibit the growth of tuberculosis, dysentery and typhoid, and make the indoor air clean and hygienic.
Most plants carry out photosynthesis during the day, absorbing carbon dioxide and releasing oxygen; Breathe in oxygen at night and release carbon dioxide. Some plants, such as cactus, release carbon dioxide during the day and absorb carbon dioxide at night to release oxygen, so that cactus can replenish oxygen in the room at night, which is beneficial to sleep.
