የአቧራ ጭምብልን እንዴት መምረጥ ይቻላል?

ስለ አቧራ ጭምብል ሲናገር በእውነቱ አንድ ዓይነት የግል መከላከያ መሣሪያዎች ነው ፡፡ የተለመዱ ጭምብሎች የጉንፋንን አካላት ጣልቃ ገብነት በብቃት ከመግታት ባለፈ የተከለከለ አተነፋፈስን ማረጋገጥ አለባቸው ፡፡ መምረጥ የተሻለ ነውነጠላ-ኮርእናባለ ሁለት ኮር disposable nose wires. Masks can better fit the bridge of the noseእናface. The filtration efficiency of disposable masks is sufficient for dust prevention. Secondly, the airtightness is good, but the airtightness cannot be too high. For example, the airtightness of KN95 masks is too high,እናit will feel breathless when worn on hot days. , Its comfort is very poor.

      This reminds the general public to treat the relevant instructions on the product packaging rationally when choosing dust masks, choose masks with high filtration efficiencyእናgood air permeability,እናdo not wear masks for a long time to avoid hypoxia damage to the lungs.
