The general people all know that after the house is decorated, we should let out the air to live, because we need to smell, but after that, we are sure that there will still be formaldehyde in the room, how should we get rid of it?
Plant absorption method: plants have strong ability to absorb formaldehyde, such as cactus, Chlorophytum, reed, ivy, iron tree, chrysanthemum, etc.
Many plants do have the function of purifying the air. However, this does not mean that plants can completely remove formaldehyde in the air. The absorption of formaldehyde by plants can only play an auxiliary role in the whole process of air purification. If the formaldehyde content in the air is too high, it may even cause the death of the plant itself. Generally speaking, the effect of formaldehyde absorption of plants with large leaf surface and vanilla is better, such as Chlorophytum, Huwei orchid, etc.
Folk way: put tea dregs, grapefruit peel, onion slices and pineapple pieces in the newly decorated room or fumigate the whole room with white vinegar.

In fact, onion slices, pineapple pieces and other soil methods can only play a role of covering, such as covering the peculiar smell of toilets. But these things don't absorb formaldehyde in the air. In addition to these things, some people also like to use perfume and air freshener. This is not advisable, because the chemical materials in perfume and air fresheners may react with the substances in the air, resulting in two pollution.
Activated carbon adsorption method: solid activated carbon has many pores, which has strong adsorption and decomposition effect on formaldehyde and other harmful substances. The smaller the particles of activated carbon, the better the adsorption effect.
The adsorption of formaldehyde by activated carbon is obvious, but the amount of activated carbon is different according to the size of space. In addition, the activated carbon needs to be replaced after adsorption to a certain extent. Although the effect of activated carbon is good, but like other methods, it can not completely remove formaldehyde in the air.
Photocatalyst decomposition method: under the stimulation of light, the catalyst in the photocatalyst generates negative ions and oxyhydrogen radicals with oxygen and water in the air, which can oxidize and decompose various organic and inorganic pollutants, and finally degrade into harmless substances such as carbon dioxide, water and corresponding acids, so as to achieve the function of decomposition of pollutants and purification of air.
Experiments show that photocatalyst is effective in absorbing formaldehyde. As a new type of material, photocatalyst will not cause secondary pollution in theory. However, due to the different process of photocatalyst production, it can not be said that photocatalyst will not cause secondary pollution. In addition, the operation of photocatalyst is complex, which is generally provided by a special service company.
Purifier treatment method: the air purifiers on the market are divided into anion type, ozone type, filtration adsorption type, electrostatic integrated type and photocatalyst type. Different air purifiers have different working principles. For example, the anion type is to produce anion, decompose the peculiar smell and attached smoke in the air, so as to achieve the purpose of purifying indoor air.
Air purifier has certain effect in absorbing formaldehyde, but it is only effective in closed space. If the air purifier is used with the windows open, it will not only have little effect but also waste electricity.
Chemical purification method: at present, there are two kinds of formaldehyde capture agents on the market: one is to purify the air by neutralizing formaldehyde and generating harmless substances; the other is to purify the air by blocking formaldehyde and preventing its volatilization.
Formaldehyde catcher is also an effective way to absorb formaldehyde. At present, some people think that formaldehyde sealer completely limits the volatilization of formaldehyde, in fact, formaldehyde sealer can not completely seal formaldehyde, only reduce the emission of formaldehyde, so it is not correct to think that the sealed formaldehyde will erupt at some time.
