When decorating a new house, what mask should I choose

Now the life of the mask is essential, haze days travel need to wear masks, chemical laboratory also need gas masks. There are many kinds of facial mask. Activated carbon mask is widely used in facial mask. Activated carbon mask has the functions of anti-virus, deodorizing, filtering bacteria and dedusting.

So the question is, can activated carbon masks prevent formaldehyde? In fact, the protective effect of activated carbon on formaldehyde is not very obvious. A good way to prevent formaldehyde is not to contact objects containing formaldehyde, and open windows to maintain indoor ventilation. In addition, some activated carbon can be placed at home to adsorb formaldehyde in the air to the room
Why activated carbon mask can prevent formaldehyde, so how to prevent formaldehyde? The gas mask can prevent formaldehyde, and the filter matched with the function of preventing formaldehyde can effectively prevent formaldehyde gas.
Formalin is a toxic gas, long-term inhalation has great harm to human body, such as cancer. For this kind of harmful gas, more advanced protection measures must be adopted. It is recommended to use gas mask to prevent formaldehyde vapor, but not gas mask. If the formaldehyde concentration exceeds 10 times or less, it is recommended to use the half face mask with formaldehyde filter box. 1
Please select the protection level and look at the dust in the environment:
If it only contains harmful gas, the selection of general tank can meet the requirements; If there is dust, the tank should be integrated. Comprehensive filter can determine the performance level of filter ash according to the filter level
Filtration efficiency of general capacity: ≥ 95.0%;
Medium volume filtration efficiency: ≥ 99.0%;
High filtration efficiency: ≥ 99.99%.
The higher the dust-proof level of the filter cartridge, the smaller the particle diameter, the better the filtering effect.
In a word, the way to choose a pot is to see the type of protection, the level of protection and whether there is dust.
