How to remove formaldehyde after house decoration?

1 First, we can start with the characteristics of formaldehyde. Formaldehyde is a volatile substance, so the first thing to do after the renovation of a new house is to keep the house ventilated for at least 2 months, and then treat it when the smell is gone. At the same time, because the volatilization speed of formaldehyde is very slow, the volatilization speed of formaldehyde can be accelerated by adjusting the indoor temperature and humidity.

2. The method of adsorbing in addition to formaldehyde by activated carbon is also very good. Activated carbon has a good adsorption to formaldehyde, and the newly renovated house has a high formaldehyde concentration. Therefore, 50g of activated carbon per square meter can adsorb formaldehyde well indoors, but at the same time, attention should be paid to the replacement of activated carbon, which is usually replaced once every 7-8 months.

3. It is also possible to remove formaldehyde with Maya Blue, which has the same adsorption function. Different from activated carbon, Maya Blue can not only adsorb pollution, but also decompose pollution into harmless gases to prevent secondary pollution. Generally speaking, Maya Blue can be used for three to five years, and it doesn't need to be replaced immediately.
