In the early winter, fine dust once covered our country. More and more people are seeking masks from the fear of fine dust that may come again. Experts stress that wearing a government-certified mask correctly prevents the inhalation of fine dust. The use of a normal mask is useless because fine dust with a diameter of 10 micrometers or less passes through as it is. If you don't wear the certified mask properly, it becomes useless.
KF80, KF94, and KF99 are labeled as health masks certified by the Ministry of Food and Drug Safety. The higher the number, the more fine particles and fine dust are filtered out, but the more difficult it is to breathe.
Therefore, 'KF80' and 'KF94' are often used. KF stands for certified products that block dust. The number after KF means the particle blocking rate of fine dust. The 'KF94' mask blocks over 94% of 0.4㎛ microparticles, and the 'KF80' blocks 80% or more of 0.6㎛ microparticles.
There are two types of fine dust masks, folding type and cup type, and wearing methods are different.
The folding type spreads the mask with both hands and grasps the ends of both wings. Afterwards, the fixed seam or nose support with the part up, you can wear a chin, nose and mouth completely covered. The hair straps should be pulled firmly against the ear, leaving no gaps. After wearing the mask, cover the entire mask with both hands and breathe to make sure there are no voids.
Cups allow the mask to cover the nose and chin. Then grab the mask with one hand and hang the upper strap on the back of the head and the lower strap on the nape of the neck. Finally, you can wrap the entire mask with both hands to make sure there are no empty spaces. 'It's hard to breathe and stuffy' to feel the mask is wearing properly.
Be careful not to wash and reuse the mask as it will lose its functionality. Even if you reuse without washing, it should be avoided because the filter function is deteriorated and it is contaminated with dust or bacteria.
