1．绿盾 pm2.5 口罩，为现今市面上真正防 pm2.5 颗粒的口罩。该口罩的亮点还在于它除了能真正防 PM2.5，面料选用了康纶纤维能杀超级细菌的面料。因此具有防尘、防菌的功能。有零售百姓家用等各种类型。
1. The Green Shield PM2.5 mask is a real anti-pm2.5 particle mask on the market today. The highlight of the mask is that in addition to its real PM2.5 resistance, the fabric uses the fabric of Conlon fiber which can kill super bacteria. Therefore, the utility model has the functions of dust prevention and bacteria prevention. There are various types of retail households.
2. （N95）口罩：合符美国国家职业安全及健康协会标准（NIOSH）N95 认可，隔滤的微粒，直径可小至 0.3 微米。在测试中，隔阻直径 0.075 微米的微粒，成功率有 95%。冠状病毒肺炎（非典型肺炎）病毒的直径约 0.1 至 0.12 微米。
2. (N95) respirator: in accordance with the national occupational safety and Health Association standard (NIOSH) N95, it is a filter separated particle with a diameter as small as 0.3 μ M. In the test, 95% of the particles with a diameter of 0.075 μ m were isolated. The diameter of coronavirus pneumonia (SARS) virus is about 0.1 to 0.12 μ M.
3. 外科手术口罩：用三层“不织布（non-woven）”制造，手术室环境适合使用；可阻隔直径约 4 微米以上微粒。
3. Surgical mask: it is made of three layers of “non woven”, which is suitable for operating room environment; it can block particles with a diameter of more than 4 microns.
4. 活性碳医用口罩：加入的活性碳用料，最主要作用是隔味，不是防菌病毒，而且呼吸阻力会加大，隔菌功能 98%。
4. Active carbon medical mask: the main function of the added active carbon material is to prevent odor, not bacteria and virus, and the respiratory resistance will increase, with the function of bacteria isolation of 98%.
