Discussion on whether active carbon mask can prevent formaldehyde
All the active carbon masks can't prevent formaldehyde. Ordinary four-layer active carbon mask can only prevent peculiar smell and dust, while some high-performance active carbon masks, such as 3m8247 active carbon mask, can prevent organic gas and 3m8246 active carbon mask can prevent acid gas.
Masks are a necessity in our daily life. We need to wear masks in haze days. Chemical laboratories also need gas masks. There are many kinds of masks. The active carbon masks are widely used in masks. The active carbon masks have the functions of anti poison, deodorization, bacteria filtration and dust prevention.
Active carbon mask can prevent formaldehyde. In fact, the effect of active carbon mask is not very obvious. The best way to prevent formaldehyde is not to touch the object containing formaldehyde, and open the window to keep indoor ventilation. In addition, some active carbon can be placed at home to absorb formaldehyde in the air. These methods are more effective than wearing active carbon mask.
Since the active carbon mask can prevent formaldehyde, how can it prevent formaldehyde? The gas mask can prevent formaldehyde. The gas filter box with anti formaldehyde function can effectively prevent formaldehyde gas.
Formaldehyde is a kind of toxic gas. It is harmful to human body if inhaled for a long time, such as cancer. For such a dangerous gas, a higher level of protection must be used. It is recommended to use gas mask to protect formaldehyde vapor. It is not recommended to use mask. If the formaldehyde concentration exceeds the standard by less than 10 times, it is recommended that you choose half mask respirator with formaldehyde filter box. If the formaldehyde concentration exceeds the standard by 10 times to 100 times, you can use full mask respirator with formaldehyde filter box.
Remind everyone to decide whether to prevent formaldehyde, whether to prevent formaldehyde for a long time, the filtration efficiency of formaldehyde prevention, and whether the product has a formal formaldehyde test report.
