Lin Nan: It's better to produce formaldehyde-free activated carbon package for urgent delivery to mother and baby. Do I need to open a window when I use it?

The function of activated carbon is auxiliary, and no amount of activated carbon can compare with the self-purification ability of nature.

Because its adsorption mode is passive adsorption, there is no pressure difference inside and outside the micropore, and only harmful gases near it can be adsorbed.

Therefore, in a room with a relatively large space, it is necessary to increase the dose.
