① Green plants
Many green plants have the ability to absorb formaldehyde, such as Phyllostachys pubescens, cyclamen, aloe, aloe, Anthurium and so on. In practical application, it is found that the adsorption capacity of green plants to indoor formaldehyde is limited. An experiment was made with Bambusa bambusa. More than 400 pots of Bambusa bambusa were placed in the room, and the initial formaldehyde was 0.23, which was left for 24 hours. It is found that the indoor formaldehyde value is 0.22, and the ability of green plants to absorb formaldehyde is far from being as strong as expected.
② pericarp
Orange peel, grapefruit peel and other peels can adsorb indoor formaldehyde, for the simple reason that the surface of the peels has a porous structure, which can adsorb formaldehyde and other substances. This kind of peel has the function of adsorbing formaldehyde in the air, which is similar to the in addition to formaldehyde principle of activated carbon and has different effects.
③ Window ventilation
Formaldehyde in indoor air can be removed because air has fluidity. Open the window, fresh air flows into the room, while indoor air containing formaldehyde flows out of the room, thus achieving the purpose of purifying indoor air.
