Fangdun7200B Half Face Mask Product Introduction

Material and Design: The mask body is made of food grade liquid silicone material, designed ergonomically to fit the Asian face shape. This material is more flexible than traditional rubber and maintains relatively stable physical properties in different temperature environments. The face mask adopts the encapsulation molding process to form an integrated structure between the silicone cover and the valve seat.

The cotton filter clip is made of ABS material, which has the characteristics of impact resistance and chemical corrosion resistance. The mask valve seat is made of PC material, which has strength and toughness. The cotton filter clip adopts a double-sided buckle design, which facilitates the installation and fixation of the cotton filter; Paired with a 45 ° knob interface, the disassembly process is relatively convenient. The air intake adopts a large area design, which helps to reduce suction resistance. The headband is made of adjustable soft material and can adapt to different head circumferences.

Usage and maintenance: Before wearing, check whether the mask is intact, confirm that the mask body is free of cracks, the exhalation valve is clean, and the opening and closing are normal. When wearing, buckle the bottom of the mask to the chin, pull it upward to cover the mouth and nose, put the headband behind the head, and adjust the tightness to fit the face without any looseness. Wipe the mask body with a mild cleaning agent after use.
