KN95 knowledge
In the GB2626-2006 standard, KN95 is the standard for dust protection and is adopted by the relevant dust industry. N95 masks are used for occupational respiratory protection, including certain dust particles (such as dust, smoke and other non-oily particulate matter protection).
The biggest feature of KN95 mask: it can prevent the spread of droplets caused by patients' body fluid or blood splash.
KN95 mask use time: depending on personal use and environment, but when breathing difficulty or discomfort is found, the mask is contaminated with foreign objects such as blood stains or droplets, the user feels that the respiratory resistance becomes larger, the mask is damaged, etc. replace.

Knowledage Corner
- dusts: little solid particles suspended in the air deriving from the crushing of solid material. Example: milling, grinding, smoothing and abrasive processes;
- smokes: very little solid particles deriving from vaporizing process and then condensation in solid material due to high heat. Example: foundry, welding and flame cutting processes;
- mists: little droplets of liquid materials deriving from atomization process of liquid materials. Example: plating, blending or production of metal dust;
- gases: substances similar to air in terms of diffusion in the environment. Gases such as carbon monoxide; carbon dioxide; nitrogen and helium;
- vapours: it is the gaseous state of substances that are solid or liquid in nature, so they generate from the evaporation of solids and liquids. Petroleum, for example, is liquid but it evaporates easily producing vapour; diluents and solvents produce vapours, too.
