Face or surgical mask – protects the environment from the virus. If you are ill and do not want to infect your children, wife, friends, you will put on a mask. The mask restrains your coughed or sneezed infectious ‘microdroplets’ so that they do not pass on. So it protects the environment from sick people. However, the virus reaches the patient from outside environment without major problems. In addition, the face mask does not provide a “tight seal” (air from the surroundings easily enters your nose etc) and therefore is not a best solution. Keep in mind that the face/surgical mask has a maximum lifetime of 2 hours, then can possibly stops functioning.
Respirator – protects a healthy person against viruses (and harmful substances) from the surroundings. Respirator – protects a healthy person against viruses like Covid-19, which are 0.3-0.5 microns in size and catch 95% of them or more.
The respirator functions in the opposite way as the cheap face/surgical mask. After it is put on, it filters the air you inhale and catches harmful substances (dust, smoke, liquid mist (so-called aerosol)) so that they do not enter your respiratory system. This is exactly what is needed when a coronavirus occurs. Respirators are available in three protection classes (FFP1, FFP2, FFP3), but for protection against viruses (incl. coronavirus), requires FFP2 or FFP3 ranges. Whether you choose a respirator with or without exhalation valve is up to you. The exhalation valve makes breathing much easier and is a great choice for a healthy person. However, if you are sick and sneezing, the valve will send the sneezed droplets to your surroundings, which you certainly don’t want to happen.
