Formaldehyde release in laminate flooring is a long-term process that usually takes years to significantly reduce. Depending on the source, this release period can range from a few months to 15 years. 12

Initial rapid release period: Newly laid laminate flooring will release most of the formaldehyde within the first 1-3 months. This stage is the peak of formaldehyde release, the concentration of formaldehyde in the indoor air is high, and special attention needs to be paid to ventilation.

Long-term slow release: Over time, the release rate of formaldehyde will gradually slow down. After 1-3 years, formaldehyde release in laminate flooring usually reaches a lower level. However, the complete dispersion of formaldehyde can take up to 15 years or more.

In summary, although most of the formaldehyde in laminate flooring may be released within 1-3 months, its complete dispersal may take up to 15 years. In this process, appropriate measures can reduce the concentration of indoor formaldehyde and protect the health of occupants.
