Since 2020, masks have become indispensable consumables in our daily life. Many practices have proved that masks are an effective means to prevent the spread of viruses. Because masks can cover people's mouth and nose, forming a direct barrier to prevent droplets and aerosols from entering the respiratory tract through our mouth and nose.

    Masks can be divided into medical masks, industrial protective masks and daily protective masks according to their purpose. Among them, medical masks are mainly used in the medical environment, which requires high bacterial filtration efficiency to filter airborne bacteria, virus attached particles and droplets. However, in order to ensure high filtration efficiency, a problem that cannot be ignored arises, that is, the heavy respiratory resistance. The filtering efficiency and breathability of masks are a pair of contradictory. The higher the filtration efficiency, the higher the resistance. The respiratory resistance of mask will bring additional respiratory burden to the cardiopulmonary system, especially for the elderly, children and people with weak cardiopulmonary function. Wearing for a long time may cause chest tightness, dizziness or lung damage.

    Therefore, great masks need to give consideration to both high filtering efficiency and low respiratory resistance, reducing respiratory burden and improving wearing comfort. This is the original intention of the design and development of KINGFA High-breathability, Low Respiratory Resistance Mask.

    Through the test comparison data table below, we can intuitively see the air permeability, technical advantages and advanced materials of KINGFA high-breathability, low respiratory resistance masks compared with ordinary masks.

    KINGFA High-breathability, Low Respiratory Resistance Masks are made by controllable rheological technology and melt blown deep friction electret technology. Among them, controllable rheological technology includes controllable rheological degradation mechanism, degradation product detection and control technology and non-peroxide controllable rheological degradation technology; melt blown deep friction electret technology includes in-situ deep electret technology research and ultrapure water friction electret technology. The superior high-breathability and low resistance performance is mainly realized by the long-term deep friction electret technology.
