Can charcoal remove formaldehyde?

Decoration will inevitably leave formaldehyde. For the sake of human health, you need to remove formaldehyde before check -in. There are many commonly used formaldehyde methods. The physical adsorption method is one of them. charcoal is one of the commonly used adsorption tools.

The reason why charcoal can be used to remove formaldehyde is mainly because it has adsorption effects. charcoal has a large amount of micropores and transition holes, so that it not only has a high ratio of surface area, but it will be very good after the cavity is excluded from the exclusion of the holes.Adsorption performance can adsorb indoor formaldehyde to remove formaldehyde.

2. Is the effect of charcoal adsorption of formaldehyde?

charcoal can be used to adsorb formaldehyde, but its dehumination effect is relatively general:

1. Ordinary charcoal has a certain adsorption effect, but its adsorption ability is unstable, and it is vulnerable to changes in the environment. It may absorb other substances. When reaching saturationEssence

2. There is a product in charcoal that is activated carbon. Its formaldehyde removal effect is better than ordinary charcoal, but the adsorption capacity of activated carbon is less adsorbed. Generally, it will be fully absorbed, and if there is too little, it will not work.

In general, charcoal can adsorb formaldehyde, but in many methods of removing formaldehyde, the effect of removing formaldehyde in charcoal is not particularly good. removing formaldehyde can still be ventilated by opening windows.

Third, how long is the charcoal removing formaldehyde to change again

charcoal uses adsorption to remove formaldehyde. When charcoal is filled, it needs to be replaced, otherwise it will release the formaldehyde inside. How often do the charcoal removed formaldehyde?

Generally, the replacement time of charcoal is related to the formaldehyde concentration of the house. The formaldehyde volatilization will be more powerful. It is recommended to change it once a week. If you change it, you can place it under the sun and reuse it.Consider change every 3-6 months.
