What are in addition to formaldehyde's methods?

1. Window ventilation: Window ventilation is the simplest and most direct method in in addition to formaldehyde, but in addition to formaldehyde is a long-term work, and the effect of window ventilation is slow, so it can only be used as an auxiliary method.

2, activated carbon adsorption: activated carbon is cheap, simple and practical, harmless to human body. There are many small holes and gaps in it. This method of physical adsorption of formaldehyde has a certain effect, but the adsorption effect will disappear after 1 month. After adsorption saturation, the activated carbon will release some harmful gases that have been adsorbed and need to be replaced regularly.

3. Purification of green plants: plants such as Chlorophytum, Crotalaria, and Chlorella can purify the air through photosynthesis, and can also purify some formaldehyde gas. However, the adsorption capacity of plants is limited after all, and photosynthesis has no effect at night.

4. Air purifier: The air purifier can remove a certain amount of formaldehyde in a certain period of time, but formaldehyde exists in the decoration materials and is continuously released, so this method treats the symptoms rather than the root cause.

5. Photocatalyst in addition to formaldehyde: Photocatalyst in addition to formaldehyde technology is generally selected by professional in addition to formaldehyde companies at present. The principle is to directly decompose formaldehyde into harmless substances such as water and carbon dioxide through photosynthesis. This technology is efficient, safe, comprehensive and sustainable.
