Negative oxygen ion mask

    The negative oxygen ion mask consists of three layers. The outermost layer is made of PT cotton-polyester fabric with three-dimensional tailoring to maximize the ventilation space. The middle layer is made of PTFE nano melt blown cloth, which can effectively filter harmful particles and bacteria in the air. The innermost layer is made of negative oxygen ion pure cotton textile type A fabric, which is gentle and close to the skin, which can be worn for a long time and remains comfortable. In the middle filter layer, the fiber composition has a pore diameter of about 0.1-0.2 microns, and the filtering effect reaches 99.7%. And the mask adopts the core technology of AMIC negative oxygen ion excitation factor to effectively prevent bacteria and harmful particles.

（1）Adopt nano-microelectric technology, PTFE nano-melt blown layer, filtration efficiency is greater than 95%.

（2）Anti-haze and anti-bacterial, filter PM2.5 harmful particles in the air.

（3）Prevent dust, car exhaust, second-hand smoke and pollen.

（4）It can be washed and cleaned and reused to reduce costs. The number of cleanings can be up to 20 times.
