SPECIFICATIONS Filter Efficiency: Up to 95%(0.075μm particles) Certification: GB2626-2006 KN95 Material: Non-woven fabric Color: White Size: Unisex, suit for women and men Package: 10 Pack Mask The KN95 face mask was made of premium cotton and non-woven fabric provides the feature of soft texture, you can sit on the face comfortably, seal correctly around mouth and face, Built-in an adjustable nose clip with soft foam fits almost any size/shape face, Elastic earloop has enough elasticity to make a good seal, not tight. It’s ideal for: fog and cold weather, anti-flu, virus, wild fires, garden mowing, asthma, house decoration, pollen allergy and other outdoor activities. Healthy Breathing – 5 Layer Protection, can filter out fine dust,pollen,allergies and almost 95% particles in the air. 3D Design – M-shaped nose clip, dust mask is cut in 3D fits almost any size/shape face, High elastic ear strap has enough elasticity to make a good seal, not tight. 95% Filter Efficiency – KN95 mask is made of non-woven fabric, which is non-irritating and non-allergenic to the skin. Its filtration efficiency (dust-removing rate) is more than 95% for non-oily particulate matter above 0.075 microns, and the filter material is harmless to the human body. KN95 VS N95 The N95 mask is actually a respirator, a respirator that is designed to be more tightly attached to the face than a common mask, and can filter particles in the air very effectively. where n denotes notresistanttooil, which can be used to protect against non-oil suspended particles;95 means that the filtration efficiency is greater than or equal to 95%, indicating that after careful testing, this respirator can block at least 95% of the very small (0.3 micron grade) test particles. KN95 is one of the levels specified in the Chinese Standard GB2626-2006. N95 is one of the levels specified in the US Standard 42 CFR 84. These two levels of technical requirements, testing methods and so on are basically the same, the filtration efficiency is 95% under the corresponding standard.

The coronavirus spreads from person to person, usually when someone is exposed to the secretions of an infected person. The infectious power of the virus directly affects the transmission route. Exposure to the body fluid from the infected person`s coughing or sneezing, or shaking hands with the infected person can lead to infection. If your hand touches something the infected person has touched and then touches your own mouth, nose, or eyes, it may also infect the virus. Normally, there`s about a liter of fluid in a person`s lungs, which sprays out like a squeezed mineral water bottle every time they sneeze. When they arrive in vitro, they are divided into more than 40,000 small drops, each containing a large number of viruses and bacteria. The fluid can travel up to 35 m/s and travel at a distance of 3 to 8 m due to massive thrust. Come on, this picture is more intuitive. So be sure to wear a mask to protect yourself and family! ! ! Wear a mask to stop you from inhaling the virus directly from the droplets, even if you`re in contact with an infected person.
