What are the skill for choosing disposable face mask in daily life?
First, dust suppression efficiency
The dust blocking efficiency of disposable face mask is based on its blocking efficiency for fine dust, especially for respirable dust below 2.5 microns. Because the dust of this particle size can directly enter the alveoli and have a great impact on human health. Dust masks are made of activated carbon fiber mats or non-woven fabrics. Those respirable dust less than 2.5 microns pass through this filter.
Second, the degree of tightness
The anti-side leakage design of disposable face mask is a technical requirement to prevent air from being inhaled through the gap between the mask and the human face without filtering. Air is like a stream of water, where the resistance is small, it flows first. When the shape of the mask is not close to the human face, the dangerous objects in the air will leak in from the tightness and enter the human respiratory tract. So, even if you choose a mask with the best filter material, it cannot protect your health. Many foreign regulations and standards stipulate that workers should regularly test the tightness of masks. The purpose is to ensure that workers choose masks of appropriate size and wear masks in the correct steps.
Third, comfortable to wear
The maintenance-free masks in foreign countries do not need to be cleaned or replaced. When the dust barrier is saturated or the mask is damaged, it will be discarded. This not only guarantees the hygiene of the mask but also saves the workers the time and energy to maintain the mask. Moreover, many masks adopt arched shapes, which can not only ensure a good fit with the shape of the human face, but also retain a certain amount of space in the mouth and nose, and are comfortable to wear.
Through the above, everyone has learned the skills of choosing disposable face mask. However, we still need to remind consumers that the wearing time of disposable face mask should not be too long. Generally, new masks need to be replaced within 8 hours.
