Respirator Free Sample Disposable filtering respirator is a kind of protective face mask which adopts PPE standard in Europe and is same with KN95. Features: KN95 masks are used for occupational respiratory protection, including protection of certain dust particles (such as dust, smoke and other non-oily particles). The biggest feature of the KN95 mask is that it can prevent droplet infection caused by the patient’s body fluid or blood splash. Packing method 1. Vacuum bag 1800 pcs/carton, 2 pcs/bag Carton size: 80*56*38 cm Gross weight: 18 kg 2. Box 1600 pcs/carton, 40 boxes/carton, 40 pcs/box (8 bags/ box, 5 pcs/bag) Carton size: 70*52* 36.5cm Gross weight: 14.5 kg How to wear a mask correctly If a good mask is used incorrectly, it will not have any anti-haze effect, so this small detail cannot be ignored. When wearing a mask, it must be close to the face. 1. Before wearing an unused mask, loosen the headband every 2 to 4 cm and pass your hand through the mask headband. The colored side of the mask faces outwards, and the side with the metal sheet faces upwards. 2. Put the mask on and close to the face, pull the upper headband behind the head, then pull the lower headband over the head, place it behind the head, and adjust the mask to a comfortable position. 3. Put your fingertips along the metal strip of the nose bridge from the middle to both sides, and slowly press inward until it is close to the bridge of the nose. Do not pinch the metal strip of the nose bridge with one hand. This will cause the metal strip to have acute angles, puncture the skin, and will As a result, the sealing is not strict enough and the protective performance is reduced. 4. Cover the mask with both hands as much as possible and conduct positive and negative pressure tests. Positive pressure test: cover the mask with both hands, and then exhale vigorously. If the air overflows from the edge of the mask, it means that it is improperly worn. The headband and the metal strip of the nose bridge must be adjusted again. Negative pressure test: cover the mask with both hands, and then inhale vigorously. The center of the mask will be sunken. If air enters from the edge of the mask, it means that it is improperly worn. The headband and the metal strip of the nose bridge must be adjusted again. Do not enter the air-polluted area before adjusting the mask to the proper position. Precautions 1. When used for oily particulate protection, the accumulative use time of class R does not exceed 8 hours at one time; the accumulative use time of class P does not exceed 40 hours, or the cumulative use time reaches 30 days from the start, whichever comes earlier. 2. Protective masks cannot be washed with water, because washing with water will destroy the filter material of the mask and the structure of the mask; if it is not contaminated or damaged, and meets the hygiene requirements, it can be considered for reuse. 3. N95 mask is not a product trademark or brand. N95 is the lowest level requirement of NIOSH (National Institute of Occupational Safety and Health) for the filtration efficiency of American occupational anti-particulate respirators. It refers to non-oily respirators under the test conditions specified in the standard. The filtration efficiency of particulate matter (such as dust, paint mist, acid mist, microorganisms, etc.) is at least 95%. 4. The higher the filtering efficiency of the mask, the greater the resistance to breathing. Therefore, wearing N95 masks for a long time is not good for the body, so do not wear them for a long time. 5. Regarding the frequency of mask replacement, no country has made clear regulations on the use time of masks. The user is required to decide how long to use the mask according to the environment and conditions of use of the mask. FAQ 1.Where is your factory located? How can I visit to your factory?
