Both N95 and KN95 masks are rated to filter 95% of 0.3-micron particles from the surrounding air. Because of the coronavirus pandemic, you use a facemask to protect yourself against most airborne particles. KN95 mask gives you respiratory protection against particles but not harmful gases and vapors as indicated on GB2626-2006 Standard. To be a certified KN95, mask manufacturers in China must pass the required government’s Mask Fit Test on humans with ≤ 8% leakage. Scope KN95 conforms to GB2626-2006 China National Standard (become GB2626-2019 on July 1, 2020) as a non-powered air-purifying respirator that provides respiratory protection against particles. The particles are such as those resulting from PM 2.5 air pollution, wildfires, volcanic eruptions, or bioaerosols like viruses. It does not protect you against harmful gases and vapors in anoxic environments, underwater operations, escape, and firefighting. KN95 mask is one of the self-absorption filtered respiratory protection products described in GB2626-2006 Standard for the protection of different types of non-oil-based particles. This article discusses the technical requirements of the reusable KN95 mask. Technical Requirements KN95 for sale KN95 complies with the technical requirements specified for non-powered air-purifying particulate respirator which includes: General requirements Visual inspection Filtration efficiency Leakability Respiratory resistance Breathing Valves Dead space Perspectives Headbands Connections and connecting parts Lenses (not applicable to KN95) Airtightness Flammability Cleaning and disinfection Information to be provided by the manufacturer Packaging General Requirements The two general requirements are the materials and structural designs. The material of the KN95 masks in direct contact with the human face is safe to the skin. It has filter media that don’t harm humans. It has sufficient strength and won’t deform or break during normal usage. The KN95 mask has the following structural designs. It provides safety to the user in terms of design, composition, and installation, and resists any structural damage. The replaceable half-mask KN95 and full mask KN95 have replaceable headband design. The headband design of KN95 is adjustable, easy to wear-and-remove, securely fastens the mask to the face, and worn without noticeable compression signs or pain. It has a small dead space and a large field of view as much as possible. When worn or it’s fogging, the lenses of the full hood don’t affect the vision. The head movement or the movement of the user don’t interfere with the fit of the mask and should not obstruct or restrict airflow when using a respiratory catheter. The disposable KN95 mask design ensures a close fit to the face and doesn’t deform during its use case. Visual Inspection KN95 mask for sale The surface of KN95 is not damaged, no deformed, and has no other visible defects. Under normal conditions of use, temperature, humidity, and encountered mechanical shock, the materials and structural parts of KN95 can stand through. The headband design of the mask is replaceable, adjustable, and with a mask lens that won’t fog and other conditions when worn affecting vision. When subject to the pre-treatment method with temperature, humidity, and encountered mechanical shock, the parts of KN95 are not ousted, damaged, or distorted. Filtration Efficiency KN95 uses a Class N filter element that detects sodium chloride (NaCl) with a filtration efficiency of ≥ 95.0%. Leakability When evaluated on TIL (Total Leakage Rate), the KN95 mask has a <8% level of leakage. Respiratory Resistance KN95 has total inhalation resistance that doesn’t exceed the maximum pressure of 350 Pa and 250 Pa too for the total exhalation resistance. Breathing Valves Breathing valve airtightness of a negative pressure system is less than 1180Pa when the pumping flow rate reaches 500mL/min. Then, the breathing valve returns to normal pressure in less than 20 seconds. When an axial pulling force is applied, the respiratory valve cover won’t move, crack, or deform. The tensile strength for a disposable face mask is 10N for 10S and 50N for 10S for a replaceable face mask. Dead Space The mean value of the results should not be greater than 1% when the dead space expressed as a volume fraction of carbon dioxide in the inhaled gas. Perspectives The field of view of the half mask (including the filter element) is ≥60° view from below. Both large-eyed and double-eyed window full masks have a general vision of ≥70%. For the binocular vision, a large-eyed window full mask is ≥80% while for a double-eye window full mask is ≥ 20%. Headbands KN95 masks for sales When subject to tension, every adjusting part like the headband and buckle of the KN95 mask won’t break or slip. Connections and connecting parts When subject to axial tension, all connecting parts should not break, slip, or deform. These connections are between the replaceable filter element and the breathing conduit of the mask. Lenses Not applicable to KN95. Airtightness Under testing conditions, the negative pressure drops not greater than 100 Pa within the 60S. Flammability testing The duration of the combustion should not exceed 5S when exposed to the flame. Cleaning and disinfection The manufacturers recommend cleaning or disinfection treatments for the KN95 mask when used more than once. So, these are the reusable KN95 masks. Information to be provided by the manufacturer The manufacturer gives correct information on the KN95 mask through GB/T 18664. 5.15.1 and summary of testing requirements. The information provided by the manufacturer should be clear with explanations, part numbers, and notations. The following requirements are to provide the minimum sales package, should have a description in Chinese, respond to any queries (about the suitability, hair under the closed frame causing the mask to leak, and air quality like pollutants, hypoxia, etc.), and should include the following information to the users: scope and limitations of the application user method for full single or half mask when using a replaceable filter the assembly method of replaceable hoods inspection method before use wearing and airtightness check method advice on when to replace filter elements maintenance methods like cleaning and disinfection methods, storage methods the meaning of any symbols and icons used Packaging KN95 masks should be visually inspected based on the technical requirements before packaging. The packaging should protect the product from mechanical damage and contamination before use. Reviews There are no reviews yet.
