The decoration of new houses needs to pay attention to the superposition of formaldehyde, that is, the formaldehyde content of single furniture, coatings, etc. is qualified, but the formaldehyde content in the interior is exceeded. Inhaling excessive amounts of formaldehyde in a short period of time may cause you to feel dizzy, nausea, eyes, nose and throat discomfort, itching, etc. Exposure to excessive formaldehyde for a long time can lead to decreased immunity and even have a malignant effect on physical health.

If you want to stay healthy and secure, effective aldehyde removal is essential

1. Ventilation is the universal law, to ensure a long time of ventilation, and at the same time it is best to ensure high temperature and high humidity.

2. Aldehyde removal spray: select some high-quality photophyll that decomposes the source of formaldehyde pollution to achieve the effect of removing decomposition. This section has no requirements for light and ultraviolet rays, and will not decompose incompletely.

3. Ye Guang mud, activated carbon. This kind of formaldehyde can be physically adsorbed, but activated carbon has the problem of easy saturation and frequent replacement. Ye Guangni is more trouble-free, has stronger adsorption, and can also decompose adsorbates, and will not be released twice.

4. Green plants and flowers. Theoretically, it is effective for the removal of aldehydes. However, it cannot remove aldehydes in large quantities and quickly, so it is mainly used for landscaping the indoor environment.

5. Air purifier. We need to understand that the main function of air purifiers is to deal with outdoor problems rather than indoor aldehyde removal, therefore, this is not as effective as ventilation in terms of aldezha removal, and I personally feel that it is not very necessary.

Above, choose the removal method according to your actual situation, and move into a new home after it is safe.
