One of highly effective filtering nonwovens of melt-blown type is an equipment designed to be used as a respiratory equipment protecting against inhaling hazardous industrial aerosols. Such equipment is often designed as disposable and as a result the cost of its utilization is a heavy burden for the employers. Due to that fact the numerous research works are undertaken to create production possibilities for nonwovens, which would include biodegradable polymers. This work presents results of research connected with applying a polylactic acid (PLA) for production of melt-blown electret nonwovens as a base in creating and filtering half-masks. The results of research on agreement with standards harmonized with the 89/686/EWG directive, indicate that the equipment fulfills the requirements as far as the highest efficiency of protection is concerned. However, due to occurrence of non-biodegradable construction elements (i.e. exhalation valve, nose clamp, head harness), further technological research in this field is necessary.
