      • Importance of fit
      Выберите ваш город

      Every time you take a breath, air rushes into your lungs. While it is easy to take breathing for granted, maintaining a healthy respiratory system is essential. Respirators are an effective means of protecting the whole of the respiratory system. Respirators work by sealing off the nose and mouth from the environment. For a respirator to fully protect you, all incoming air must pass through a set of filters which remove targeted harmful substances.

      Sadly, humans have a poor ability to ascertain if a respirator fits. Fit testing should be performed every time you get a new size or model of respirator to ensure it fits properly.

      Before each use, the user must check the correct assembly of the respirator and check its correct donning and tightness, since the effectiveness of protection significantly depends on this:

      1. Put on the assembled respirator, so that the mask fits snugly to the face without distortions and heavy pressure. Place the palm of the hand over the exhalation valve cover and exhale gently. If the mask bulges slightly and no air leakage is detected, a proper fit has been achieved.
      2. If air leakage is detected, check the tightness of the mask. Remove the filters. Cover the holes in the saddles of inhalation valve on the side surfaces with your hands. Take 2-3 deep breaths and hold your breath for a while. If it is impossible to breathe and the mask shrinks slightly, then the mask fits snugly to the face, the size of the mask is chosen correctly. If air passes under the mask and it straightens out, then you should provide additional checking or try a mask of a different size.

      Always remember that fit testing is essential. Our specialists always offer advice on the correct fitting and usage of RPE.
